💡 Result:
Yes. For a **synchronous** Nova Embeddings request, the schema requires `taskType: "SINGLE_EMBEDDING"`. For text input, provide either `singleEmbeddingParams.text.value` (inline text) **or** `singleEmbeddingParams.text.source` (a text file in S3). The S3 `source` uses a `s3Location`. ([docs.aws.amazon.com](https://docs.aws.amazon.com/nova/latest/userguide/embeddings-schema.html?utm_source=openai))
The docs distinguish synchronous requests from asynchronous ones: synchronous requests support S3 inputs and inline content; asynchronous requests are for longer content and require S3 inputs.

Preserve valid S3 text inputs.
Nova synchronous SINGLE_EMBEDDING requests accept singleEmbeddingParams.text.source.s3Location as well as text.value. The current branch rejects S3 text before the provider call, so native InvokeModel clients cannot embed S3 text through this route.
Preserve the native text source through canonical conversion and outbound reconstruction. Keep S3 retrieval outside the converter. Raw-body passthrough is also acceptable only if this request shape uses the repository’s native passthrough path.

## ✨ Features
- **Agent Gateway (A2A)** - Bifrost now proxies A2A agents. Register an
upstream agent by its agent card URL (`POST /api/agents`, `POST
/api/agents/inspect`, or the new top-level `agents` array in
config.json, reconciled by name at startup) and clients reach it at
`/agents/a2a/<name>/.well-known/agent-card.json`,
`/agents/a2a/<name>/json-rpc` (JSON-RPC and SSE streaming) and
`/agents/a2a/<name>/rest/...`, plus an optional shared gRPC listener
routed by `<agent>.<a2a_grpc_base_domain>:<a2a_grpc_port>`. The runtime
caches cards and clients, refreshes a stale interface on
404/405/410/426, supports header, OAuth and TLS upstream auth, runs A2A
plugin hooks, and delivers push notifications through a durable, retried
outbox (`/agents/a2a/<name>/push/callback`, authenticated with a
per-config token). Push callbacks to loopback or private addresses stay
blocked unless the new `server.a2a_allow_private_push_callbacks` is on
(default off). Access is governed per virtual key with `agent_grants`
(omit to keep, `[]` to clear, unknown agents rejected atomically) and
`allow_by_default` per agent; ungranted or disabled agents return `403`.
Every A2A operation and stream event gets its own log row (relational,
ClickHouse, or hybrid with object-store payloads) in a new Agent Logs
workspace with session grouping, raw capture and DAC-bounded filters,
LLM and MCP logs carry the A2A correlation id, and A2A client spans plus
the `a2a.client.operation.duration` metric reach connectors. The
dashboard adds an agent sheet with auth fields and a card preview,
push-config UI and an Agent Gateway settings page; Helm adds
`bifrost.agents[]`, `bifrost.client.a2aExternalClientUrl`,
`bifrost.server.a2aGrpcBaseDomain` and `bifrost.server.a2aGrpcPort`
(#7772, #7773, #7774, #7775, #7776, #7777, #7778, #7779, #7780, #7781,
#7782, #8088, #8125, #8204, #8336, #8364)
- **Warp AI Assistant (alpha)** - Warp (formerly Odin) is a new
in-dashboard agent that answers questions about the deployment's logs,
spend, latency and governance in plain language, using read-only tools
(`query_logs`, `count_logs`, `get_log_detail`, `get_request_trace`,
`query_metrics`, `query_usage_by`, `query_model_performance`,
`render_chart`, `describe_filter_space`, `describe_virtual_key`,
`describe_user_limits`, `ask_user`). It asks multiple-choice clarifying
questions, draws inline charts, links to matching rows on the Logs page,
resolves "today", "yesterday" and bare dates in the asker's time zone,
and filters by agent name and `x-bf-agent-correlation-id`. Admins set a
default model plus up to 20 more models users can switch between,
`temperature`, `reasoning_effort` and max iterations (2 to 20) at
`/api/warp/config`; chat streams from `/api/warp/chat` with history
under `/api/warp/conversations` (100-conversation cap). Warp calls the
gateway in-process, its calls are logged and governed under the app name
**Warp**, signed-in users without an access profile are served, and it
only reads rows the asker may see. Governance refusals return their own
error codes (`access_denied`, `budget_exceeded`, `rate_limited`,
`model_blocked`), and the chat panel is a resizable dock. Gated by the
`warp` feature flag, on by default in OSS and off by default in
Enterprise (#6212, #6213, #6214, #6215, #6216, #6217, #6218, #6219,
#6220, #6221, #6882, #7068, #7070, #7086, #7151, #7183, #7418, #7511,

#8401, #8416)
- **Warp Semantic Log Search** - Completed LLM logs can be embedded into
a vector store so Warp's `semantic_search_logs` finds conversations by
meaning. The embedding provider, model, dimension and namespace are set
in Warp settings; new logs are indexed live, and older logs by a
resumable, concurrent background backfill
(`/api/warp/log-index/backfill`, `/backfill/status`, `/backfill/cancel`,
`/api/warp/log-index/status`). Restricted callers get results
prefiltered to rows they can see, the similarity threshold is one 0 to 1
scale on every vector store (default 0.5, Weaviate included), and a
finished backfill is hidden once the embedding space changes (#6847,
#6848, #6849, #6850, #6851, #6852, #7186, #7740, #7805, #7973, #8180,
#8339)
- **GPT Live Sessions** - Bifrost now proxies OpenAI GPT Live sessions
over WebSocket and WebRTC at `/v1/live/sessions`, with a sideband
`/v1/live/sessions/{session_id}/attach` WebSocket and recording
downloads at `/v1/live/sessions/{session_id}/content` (logged as
`live_content`). Voice time is billed in 30-second windows from
`input_cost_per_second` on a `live` pricing row and backend Responses
calls are billed per turn, with governance checked at each window and
one session log row carrying transcript, delegations and costs. Live has
its own `live` allowed request type (`realtime` does not imply it).
Sessions are bound to the virtual key that opened them, keys are picked
only from those governance allows, later billing units on an excluded
key return `403`, and sideband attachments run through the plugin
pipeline as `live_sideband` with their own log row. Failed backend
delegations are recorded on the delegation instead of failing the
session, an upstream that ends without `session.closed` gives the client
`502 server_error`, a failed WebRTC setup still records the 15-second
minimum, `x-bf-direct-key` works on WebSocket upgrades, and `?provider=`
or `x-model-provider` picks the provider on attach and content routes
(#7721, #7722, #7723, #7724, #7725, #7726, #7727, #7728, #7999, #8011,
#8133, #8203, #8293, #8294, #8295, #8296, #8297, #8298, #8299, #8319,
#8331, #8346, #8372, #8376, #8381, #8405, #8414)
- **Cloudflare Workers AI Provider** - New first-party `cloudflare`
provider for chat completions (streaming included), Responses,
embeddings and model listing against Workers AI. Every key needs
`cloudflare_key_config.account_id` (supports `env.` references); the
base URL defaults to `https://api.cloudflare.com/client/v4`. Clef
decision models (`clef`, `clef-flash`) are served natively on
`/v1/decisions` with image input, and the Cloudflare `{result, success,
errors}` envelope is unwrapped. A migration dialog in the UI moves an
existing custom provider named `cloudflare` onto the new provider
(#8007, #8342, #8344, #8345, #8351, #8378)
- **Provider-Injected MCP Tools** - A provider can carry
`injected_tools`, a list of `{name, mcp_client_name, tool_name}`
entries. Bifrost adds each MCP tool to every chat and Responses request
for that provider (past client and request tool filters), runs it server
side when the model calls it (non-streaming, streaming chat, streaming
Responses and the Anthropic passthrough path), and returns only the
final answer with usage summed across turns. An entry named `web_search`
replaces any native web search the client sends; any other name replaces
a client tool of the same name. Configure it in the provider's new Tools
tab, the provider API or config.json. Depth is capped by
`mcp_agent_depth` (#8021, #8022, #8023, #8024, #8025, #8026, #8027,
#8028, #8029, #8030, #8366, #8367)
- **OAuth-Minted Keys for OpenAI-Compatible Providers** - Keys on
`openai` and on custom providers with an `openai` base can set
`oauth_key_config` instead of a static `value`. Bifrost mints a bearer
from the token endpoint with the `client_credentials` grant (HTTP Basic
or `auth_style: "body"`) or the `jwt_bearer` grant (RFC 7523, RSA/EC
signed assertions), caches it per credential, refreshes it a minute
before expiry and backs off on rejected credentials. A non-empty `value`
always wins. Available in the API, config.json, Helm and a new "OAuth
(minted token)" tab in the key form. Databricks OAuth M2M and GitHub
Copilot now mint through the same shared token cache, so a rejected
Databricks service principal is backed off instead of hitting the token
endpoint on every request (#8254, #8255, #8256, #8257, #8258, #8259)
- **Decisions API in OpenAI Shape** - `POST /v1/decisions` now takes
`input` (text, messages with image parts, or structured data) and an
ordered `questions` list, each with `type` (`predicate`, `choice`,
`score`), optional `name`, `instructions`, `criteria`, `choices` or
`levels`, plus `safety_identifier`. Answers come back as a list in
question order, with Laya answer fields, response `routing` and
state/truncation usage fields passed through. New `/openai/v1/decisions`
and `/openai/decisions` routes (also under `/langchain`, `/litellm`,
`/pydanticai`) accept the OpenAI SDK's native request; an OpenAI-based
provider's body is relayed unchanged and others are rebuilt into
OpenAI's response shape (#7982, #8181, #8192)
- **Native Decision Models on More Providers** - `/v1/decisions` now
reaches native decision endpoints on OpenAI (`gpt-6-luna`), Perplexity
(`pplx-decider-*`), Ollama (local System One models `nimble`, `tev1`,
`clef`, `clef-flash`, `laya` on `/v1/systemone`, with `keep_alive` and
base64 images) and OpenRouter (TypeSafe Jev models and any model the
datasheet marks `supports_decisions`, listed live with response headers
forwarded). These providers returned `unsupported_operation` before
(#7589, #8191, #8301, #8354, #8355, #8363, #8397) (thanks
[@hcavarsan](https://github.com/hcavarsan)!)
- **Decision Emulation Is Opt-In** - Decision requests to a model with
no native decisions endpoint are no longer emulated through the model's
Responses API by default. They return `unsupported_operation` with a
message naming the model and `convert_decision_to_responses`. Enable
emulation with the new compat setting `convert_decision_to_responses`
(UI: Compatibility, "Emulate Decisions API on non-decision models") or
per request with `x-bf-compat: ["convert_decision_to_responses"]`
(#8288, #8289)
- **TypeSafe as a Custom Provider Base** - Custom providers can use
`base_provider_type: "typesafe"`, so a second TypeSafe-compatible
endpoint (for example self-hosted Laya or Nimble) runs with its own
keys, name, `allowed_requests` and `request_path_overrides` for
`decisions` and `list_models`, with keyless listing. The dashboard
offers TypeSafe as a base format and adds a Decisions toggle to allowed
requests (#7948, #7949, #7950)
- **Decision Pricing Rates** - New datasheet and override fields
`input_cost_per_token_decisions` and `output_cost_per_token_decisions`
price decisions served natively by chat-row models such as `gpt-6-luna`;
rows without them fall back to the normal token rates. Decision requests
on variable-price models no longer bill a negative cost (#8249)
- **Complexity Router Decision-Model Classifier** - The complexity
router can now classify with a decision model (TypeSafe Jev by default;
Laya, Nimble, Clef and OpenAI decision models such as `gpt-6-luna` also
work), as the primary classifier or as the semantic classifier's
fallback. Only user turns are sent (`previous_message_count`,
`timeout`), per-tier guidance (definition, signals, examples) can be
edited with shipped defaults returned as `jev_defaults` on the status
endpoint, and decision calls are billed under the routing cost with a
`RequestType`. `GET /api/models?decisions=true` lists only models that
serve decisions natively, `decisions` is a request type in pricing
overrides and routing CEL rules, decision logs show their questions, and
the LLM fallback classifier no longer sends `temperature: 0`. The
dashboard has a stepped classifier setup and settings sheets (#7485,
#7605, #7647, #7690, #7749, #8059, #8080, #8193, #8303, #8385)
- **Durable Queue Framework** - New `framework/queue` package: a durable
queue with consumer groups, at-least-once delivery, per-key ordering,
retries, dead-lettering and lease heartbeats. Backends: in-memory, and a
`logstore` type that keeps queue tables in the logs database on SQLite
(single process), Postgres (multi-instance, `SKIP LOCKED` claims,
`LISTEN/NOTIFY` wakeups) and ClickHouse. Available to framework
consumers; the gateway does not use it yet (#8217, #8218, #8219, #8220,
#8221, #8222)
- **Multimodal Embeddings** - `/v1/embeddings` input now accepts content
parts (`text`, `image`, `audio`, `video`, `file`, `tokens`) and per-item
`params` overrides, served by Cohere, Gemini (including
`:batchEmbedContents`) and Vertex (including `gs://` URIs,
`multimodalembedding@001` video segments and
`embedContentConfig.documentOcr`/`audioTrackExtraction`). Bedrock gains
Nova multimodal (`amazon.nova-2-multimodal-embeddings-v1:0`) and Titan
multimodal (`amazon.titan-embed-image-v1`) embeddings, `encoding_format`
maps to Cohere `embedding_types`, and Parasail serves embeddings.
OpenAI-compatible providers get only `encoding_format` and `dimensions`
(Mistral no longer returns `422` on `task_type`), and the semantic cache
hashes `task_type`, `title` and `auto_truncate`. Embedding inputs are
stored in a new `embedding_input` log column and shown in the log view
(#2559, #3367, #7001, #7096, #7459, #7549, #7550, #7804, #8140, #8143,
#8146, #8199)
- **Shell, apply_patch and Programmatic Tool Callers** - The Responses
API now supports OpenAI's `shell` tool with
`shell_call`/`shell_call_output` items (streaming included) and the
`apply_patch` tool with `apply_patch_call`/`apply_patch_call_output`
items and diff stream events. `allowed_callers` is translated between
OpenAI's `programmatic` and Anthropic's versioned `code_execution_*`
callers on chat and Responses. Gemini
`executableCode`/`codeExecutionResult` parts map to
`code_interpreter_call` items, and `code_interpreter` reaches Gemini as
`codeExecution`. Shell, code interpreter, image generation and computer
tools are dropped for Bedrock and Bedrock Mantle, and the semantic cache
treats `shell_call` and `apply_patch_call` as tool calls (#7292, #7293,
#7301, #7668, #7711, #8093)
- **Retrieve a Single Model** - New `GET /v1/models/{model}` returns one
model's metadata, implemented for OpenAI, Anthropic (with alias
resolution), Cohere, Gemini, Mistral and Ollama, with `shutdown_date`
where the provider announces one. Gated by the `model_retrieve` allowed
request and exempt from budgets and rate limits (#7419, #7716)
- **xAI Realtime** - xAI is now a realtime voice provider on the
WebSocket gateway, including client-secret minting through
`/v1/realtime/client_secrets`. Browser clients can authenticate with the
`xai-client-secret.<token>` subprotocol as well as
`openai-insecure-api-key.<token>`; an empty, whitespace-containing or
conflicting subprotocol credential returns `400` before the upgrade, and
mint requests that carry session settings are rejected (send them with
`session.update`). Responses streaming keeps the provider stop reason
from the newest chunk that has one, and the logging plugin marks
`refusal`, `content_filter` and `safety` stops as errors of type
`model_refusal` (#8200)
- **Bedrock Passthrough** - New `/bedrock_passthrough` route forwards
the three Bedrock operations Bifrost has no native route for:
InvokeAgent (streamed as AWS sends it), knowledge-base Retrieve, and
ApplyGuardrail. Any other path, method or malformed identifier returns
`400`. InvokeAgent and Retrieve are SigV4-signed with the key's AWS
credentials (an API-key-only key is refused with `400`), and AWS status,
body and `X-Amzn-*` headers come back unchanged. Azure
`prompt_filter_results` and per-choice `content_filter_results` are now
passed through on chat responses (#7907)
- **Vertex AI Workload Identity Federation from AWS** - Vertex keys can
set `vertex_key_config.aws_workload_identity` (`audience`,
`service_account_email`, `token_lifetime_seconds`, `aws_region`,
`aws_role_arn`) to authenticate from EKS IRSA, Pod Identity, ECS task
roles or EC2 instance profiles with no stored GCP or AWS key.
gcloud-generated AWS `external_account` JSON now also resolves AWS
credentials through the AWS SDK chain. New "Workload Identity (AWS)" tab
in the key form (#7705, #7706, #7707, #7708, #7709)
- **Web Search Priced per Request** - Provider-hosted web search is now
reported as `usage.tool_usage.web_search.num_requests` (top-level
`tool_usage` on Responses) for Anthropic, Gemini, Perplexity and OpenAI
Responses, and billed with the new pricing field
`web_search_cost_per_request`. Existing values are copied over by
migration, and datasheet rows still carrying
`search_context_cost_per_query` are read as the new field (#7624, #7687)
- **Ignore Provider-Reported Cost** - New per-provider
`ignore_provider_cost` setting (UI: provider Pricing tab, default
`false`) discards the `usage.cost` a provider reports, for providers
such as Cortecs that report credits, and prices requests from the model
catalog and pricing overrides for logs, budgets, telemetry and streamed
totals. The client response keeps the provider's figure (#8052, #8053,
#8054, #8056, #8057, #8165)
- **Compat: Route Reasoning-Only Models to Responses** - New compat
setting `force_reasoning_only_models_to_responses` sends chat completion
requests with tools to the Responses API when the datasheet marks the
model as not supporting `reasoning_with_tool_calls`, and converts the
answer back to chat format, so reasoning is kept instead of turned off.
Defaults to `true`, also available per request through `x-bf-compat`
(#7806, #7807)
- **Chat reasoning.mode and reasoning.summary** - A chat request
carrying `reasoning.mode` (`standard` or `pro`) on OpenAI or Azure is
served through the Responses API so `pro` is honoured; other providers
report it as a dropped compat param. Chat requests can also set
`reasoning.summary` (`auto`, `concise`, `detailed`), forwarded when chat
is served through the Responses API (#7955, #8214)
- **DeepSeek Served Model Tracking** - When DeepSeek serves a different
model than requested (retired IDs silently upgraded), the served model
is recorded as `ServerSideFallbackModel` for pricing and routing info,
and a datasheet `server_side_model` covers the Anthropic-compatible
endpoint, which echoes the requested ID (#7811, #7822)
- **Failure Classification and Smarter Key Rotation** - Every failed
attempt now gets a `failure_class` on the attempt trail (`credential`,
`quota`, `model_access`, `model_gone`, `region_blocked`, `rate_limit`,
`transient`, `caller_fault`, `timeout`, `cancelled`, `unknown`), read
from provider error codes rather than status alone. Credential and quota
failures hold a key out for every model; keys refused for the model, a
retired model or a region block are rotated past, and permanent per-key
failures walk the key pool even at `max_retries: 0`. Attempts Bifrost
ends itself are recorded as `timeout` (504) or `cancelled` (499).
Provider retry hints (`Retry-After`, `retry-after-ms`, Gemini
`RetryInfo`) are exposed as `extra_fields.retry_after_ms`, clamped to 1s
to 5m (#7684, #8231, e90eaf465, 00ab24c66)
- **Time-to-First-Token Cutoff** - Routing rule targets accept
`ttft_timeout_ms` (1 to 300000). A streaming attempt that does not
produce its first token in time is cut off and handed to the next
fallback without cancelling the request; the last attempt is never cut
off, and non-streaming requests are unaffected. A cut-off attempt fails
with code `ttft_timeout` and status `504` on the attempt trail. The rule
editor has a "Time to first token cutoff (ms)" field per target, also in
Helm (#7503, #7504, #7505, #7506, #7507, #7996)
- **Requested Route in Routing Info** - When a routing rule, load
balancer or session router rewrites the model or provider, the caller's
original route is returned as `routing_info.requested_provider` /
`requested_model` and in the `x-bifrost-routing-info-requested-provider`
and `x-bifrost-routing-info-requested-model` response headers (#7683)
- **Gateway Request ID Header** - Every traced response now carries
`x-bifrost-request-id`, the ID the request is logged under (`GET
/api/logs/{id}`), next to `x-bifrost-trace-id`. Provider response
headers whose names start with `x-bifrost-` are no longer forwarded to
the caller (#8101)
- **Deprecated Models Hidden from Browsing** - `GET /api/models` without
a `query` now leaves out deprecated models and their counts; with a
`query` they are kept but sorted last. Pass `include_deprecated=true` to
get them all (#7257)
- **Provider Objects Bound to the Creating Virtual Key** - Files,
batches, videos, containers (and container files) and cached contents
created through a virtual key are now recorded in a new
`provider_objects` table. Retrieve, content, delete, cancel, results and
remix on another key's object return `404`, list pages are narrowed to
the caller's own objects, and indirect references (a batch on another
key's input file, a container with `file_ids`, a request naming
`cached_content`) are checked the same way under every id form the
provider accepts. A failed ownership lookup returns `500` instead of an
unchecked page, and id lists over 1000 no longer fail large list pages.
A new **Restrict Provider Objects to the Creating Virtual Key** switch
under Settings > Security (`client.enforce_vk_object_ownership`, default
`true`, applied without a restart) turns the restriction off; creators
are still recorded while it is off (#7892, #8292, #8317, #8427, #8435)
- **File-Based Batches Under Model-Restricted Virtual Keys** - A batch
defined by `input_file_id` or `input_blob` is now judged by what the
provider actually runs. On OpenAI and Azure (and custom providers built
on them), which run the models named inside the file, the virtual key
must allow every model of the provider. On Gemini, Vertex and Bedrock
the request `model` must be present and allowed. A batch create that
sends a file or blob together with inline `requests` returns `400`
(#7891, #8318)
- **Passthrough Route Hardening** - Passthrough routes
(`/openai_passthrough`, `/anthropic_passthrough`, `/azure_passthrough`,
`/genai_passthrough` and siblings) now forward only `POST` requests to a
fixed allowlist of inference paths per provider (chat, completions,
responses, embeddings, moderations, audio, images, `generateContent`,
`countTokens`, `predict` and similar). Paths that could change the
upstream host (not rooted, `//`, userinfo `@`, schemes, backslashes,
`..`, control characters, percent-encoded forms included) are refused,
the final URL must stay on the provider's host, and `x-model-provider`
can only confirm the route's provider. The model is read strictly from
the JSON body, and governance checks every model a body names, including
each task of a Runware task array (#7855, #7890, #7959, #8321)
- **Management API Refuses Unlisted Browser Origins** - While dashboard
auth is disabled or unconfigured, and on deployments with
`config_store.enabled: false`, browser requests to `/api/*` (and `/ws`
and `/metrics` without a config store) from an origin that is not
localhost, the gateway's own origin, or listed in
`client.allowed_origins` (patterns such as `https://*.example.com` work,
a bare `*` does not count) now return `403`. Requests without an
`Origin` header (CLI, SDKs), whitelisted routes and inference routes are
unchanged, and enabling dashboard auth lifts the auth-off check (#7893,
#8300)
- **Real Auth Required for Secret References and Private Targets** -
Requests admitted only because dashboard auth is off now get `403` when
they: use `env.`/`vault.` references in MCP client credential fields
(headers, connection string, OAuth, token exchange, TLS) on `POST
/api/mcp/client` or `PUT /api/mcp/client/{id}`; create, re-point or
redeliver to a webhook endpoint with `allow_private_network`; set an
outbound endpoint (`collector_url`, `metrics_endpoint`,
`push_gateway_url`, `endpoint`, `url`, `base_url`) or any
`env.`/`vault.` reference on a built-in plugin (OTEL, telemetry); set,
change or remove a Vertex key's `vertex_key_config.auth_credentials`
(the JSON names the hosts the Google client dials); or delete MCP tool
logs via `DELETE /api/mcp-logs`. config.json provisioning is not
affected (#7886, #7887, #7913, #8330, #8335) (thanks
[@xujiantop-crypto](https://github.com/xujiantop-crypto)!)
- **Auth Config Changes Need Proof of Control** - When an admin account
exists but dashboard auth is switched off, re-enabling auth or replacing
the admin username or password through `PUT /api/config` now requires
`current_password` (the stored admin password) or a valid `setup_token`
in the request. The Security page asks for the current password in that
case (#7854)
- **Request Decompression Limits** - Compressed request bodies may now
expand to at most 100 times their compressed size (1 MiB floor,
`client.max_request_body_size_mb` ceiling), and a process-wide in-flight
budget of four times the body cap bounds buffered decompression. The
budget is charged for bytes actually inflated, so ordinary concurrent
gzip traffic is not refused (#8333, #8431)
- **Access Profiles for Teams, Business Units and Customers** -
*(enterprise)* A team, business unit or customer can hold an access
profile instead of its own budgets and rate limit, and every virtual key
under it is governed by that profile. Virtual keys can now be owned by a
business unit (`business_unit_id`), and a business unit holds at most
one budget. config.json accepts `access_profile` on `governance.teams`,
`governance.customers` and `governance.business_units`, roles accept the
new `business-unit-data` and `customer-data` data access scopes, and the
dashboard hides a key's own limit editors when a profile governs it
(#7251, #7253, #7254, #7255, #7386, #7401, #7421, #7432, #7616, #7619,
#7642, #7792, #7794, #7795, #8086, #8332, #8375, #8379)
- **Per-Virtual-Key Content Logging Control** - Virtual keys have a
tri-state `disable_content_logging`: omitted or `null` inherits
`client.disable_content_logging`, `true` keeps that key's request and
response content out of the log store and strips it from OpenTelemetry
export (MCP arguments included), `false` keeps content in the log store
even when the client setting turns it off. The per-request
`x-bf-disable-content-logging` header still wins. The virtual key editor
has an Inherit / Off / On select, and the CLI has
`--disable-content-logging` (#7476, #7477, #7478, #7479, #7480, #7481)
- **Auto-Delete Expired Virtual Keys** - Virtual keys can set
`delete_after_expire` (requires `expires_at`, `400` otherwise). A daily
job deletes flagged keys once they expire and posts one notification
with the counts. The expiry picker has a matching option (#7525, #7526,
#7527, #7828)
- **Global Proxy in config.json and for All Outbound Traffic** - The
global outbound proxy can be declared as a top-level `proxy_config` in
config.json (`enabled`, `url`, `username`, `password`, `no_proxy`,
`timeout`, `skip_tls_verify`, `enable_for_scim`, `enable_for_inference`,
`enable_for_api`) and in Helm. With `enable_for_api` on, MCP
connections, MCP OAuth discovery, model catalog sync, OpenTelemetry
export, webhooks, skill fetches and plugin downloads go through it, each
keeping its own SSRF policy. With `enable_for_inference` on, providers
without their own `proxy_config` now actually send inference through it
(the flag was stored but never read before), and multi-entry `no_proxy`
lists match on both fasthttp and net/http paths (#7568, #7574, #7575,
#7799)
- **Adaptive Routing Incidents and Attempt Metadata** - *(enterprise)*
Adaptive Routing has an **Incidents** page in the sidebar. Load balancer
decisions for each attempt are written to log metadata under the
reserved `bifrost_alb_` prefix (caller headers cannot spoof them) and
hidden from the log filter sidebar and metadata grid. Docs cover held
keys, incidents and the `/api/adaptive-routing` endpoints (#7456, #7531,
#7645, #7734, #7974, #8233, #8272, #8274)
- **Governance Dashboard Updates** - *(enterprise UI)* New Org Chart
page under Governance and an enterprise Home landing page; Business
Units navigation checks its own `BusinessUnits` permission; new
`BackgroundJobs` RBAC resource; Warp follows RBAC; create, edit, delete
and rotate controls follow the viewer's permissions with a tooltip
explaining why they are disabled; the customers list shows a server-side
team count (#7404, #7675, #7954, #7998, #8046, #8132, f6f43dff4,
18b4b3f22)
- **SSO and SCIM Updates** - Every SSO provider's SCIM block accepts
`attributeProjectMappings` (add users to existing projects when an IdP
attribute matches a value or glob; memberships granted by a rule are
revoked when it stops matching) and `bulkSyncInterval` (directory
reconcile interval, default `24h`, from `1h` to `30d`), in config.json
and Helm. The generic SSO provider accepts a login `displayName`, and a
new identity sync guide aligns the IdP setup docs (#7803, #8045, #8373)
- **Audit Logs: Omit IP Addresses** - *(enterprise)* New
`audit_logs.omit_ip_addresses` (Helm `omitIpAddresses`, default `false`)
stops recording client IPs in audit logs. New events store no
`request_ip` or initiator host, older IPs are hidden from APIs, exports
and archives (not deleted), and IP search and filters are disabled. HMAC
signatures stay valid (#7671, #8269)
- **Attribution Context Keys Deprecated** - The raw attribution context
keys (`BifrostContextKeyGovernanceVirtualKeyID`, `...TeamID`,
`...CustomerID`, `...BusinessUnitID`, `...ProjectID`, `...BudgetIDs`,
`...RateLimitIDs`, `BifrostContextKeyUserID`, `...UserName`,
`...UserEmail` and related variants) are deprecated in favour of the
`ctx.Grant()` accessors. Values and behavior are unchanged (#7975)
- **MCP Client Target Validation at Connect Time** - MCP clients
registered while dashboard auth is off now carry a server-set
`require_public_target` flag, and every later dial (reconnects, per-call
connections, proxied hops) is held to public addresses, not only the
registration-time DNS check. Existing clients default to `false` (#7849)
- **MCP OAuth Server Hardening** - Bifrost's MCP OAuth authorization
server accepts remote client callback URIs only when listed in
`client.oauth2_server_config.allowed_redirect_uris` (loopback and
`cursor://anysphere.cursor-mcp` are always allowed), re-checks existing
registrations at authorization and token exchange, and shows the exact
callback on the consent page. Oversize DCR/authorize fields
(`client_name`, `scope`, `redirect_uris`, `state`, `code_challenge`)
return `400` before anything is stored (#7851, #7960)
- **MCP OAuth Private Network Allowlist** - OAuth-protected MCP servers
on localhost or a private network can now be added. List hostnames, IPs
or CIDRs in `client.mcp_oauth_private_allowlist` (or
`mcp.tool_manager_config.oauth_private_allowlist`, which wins) and the
MCP OAuth chain (discovery, dynamic client registration, token exchange,
refresh) may reach them for clients registered by an authenticated admin
or declared in config.json. Link-local and cloud metadata addresses stay
blocked, invalid entries stop boot, and edits apply to the next
connection (#8347)
- **Virtual Key Rotation Revokes MCP OAuth Grants** - Rotating a virtual
key now revokes the MCP OAuth refresh tokens minted with its old value
and any consented but unexchanged authorization code, in the same
transaction as the rotation. OAuth consent in vk mode requires the key's
current value (#7889)
- **MCP Server Instructions** - The `instructions` an upstream MCP
server returns from its `initialize` handshake are now captured,
persisted with discovered tools and refreshed with them. Bifrost
forwards them on its own `/mcp` gateway and injects them into
MCP-bearing chat (as a leading system message) and Responses (appended
to `instructions`) requests as tagged `<mcp_server name="...">` blocks,
scoped to the servers the request can see. Caps are
`mcp.tool_manager_config.max_instructions_per_client` (default 4096
bytes), `max_instructions_total` (default 16384 bytes) and a per-client
`max_instructions_length` override. In code mode the instructions appear
in the `.pyi` stubs (#7516, #7517, #7518, #7519, #7766, #7818, #8371)
- **MCP Connection Recovery and Tool Refresh** - `POST
/api/mcp/client/{id}/refresh-tools` (and a **Refresh tools** action in
the client table) re-discovers a client's tools immediately, for every
client type including per-user and per-call clients. Tool calls that
fail because the server dropped its session ("session terminated",
"session not found", "need to re-initialize") trigger an immediate
reconnect and, where safe, a retry; a failed live-connection check now
triggers the documented reconnect, and a failed make-before-break
re-dial keeps the live connection. Health probes retry timeouts but
treat dead sessions and auth rejections as permanent. `POST
/api/mcp/client/{id}/reregister` (dashboard: "Reauthorize with a new
client") registers a new dynamic OAuth client and runs consent against
it when the upstream forgot the old `client_id` (#6921, #6922, #6923,
#6924, #6927, #6928, #6929, #6931, #7228, #7229, #7230)
- **Code Mode Execution Limits** - Code mode now runs in-process on a
pinned Starlark runtime with per-execution budgets instead of child
processes. New `mcp.tool_manager_config.code_mode_limits` (also
`client.mcp_code_mode_limits` through the config API, the MCP settings
page and Helm) sets `max_source_bytes` (default 64 KiB), `max_steps`
(1,000,000), `max_memory_bytes` (64 MiB), `max_log_bytes` (64 KiB),
`max_tool_calls` (64), `max_value_bytes` (1 MiB, minimum 1024) and
`max_nesting_depth` (64, maximum 1000). Cyclic or oversized results are
rejected before serialization (#7962)
- **Disabled MCP Clients on Virtual Keys** - Each `mcp_configs` entry on
a virtual key now shows its MCP client's `disabled` value, and the docs
explain that a disabled client offers no tools even when the key lists
it (#8130, #8270)
- **MCP Library Additions** - FXMacroData and Parlel are added to the
community MCP library (#8005, #8041) (thanks
[@roberttidball](https://github.com/roberttidball)!)
- **Semantic Cache Scoped by Identity** - Semantic cache entries are now
scoped to the identity that wrote them: the request's virtual key plus
its user, when the request is attributed to one. The scope is part of
the params hash, so it covers direct hits and semantic search alike, and
a body field named `identity_scope` cannot claim another identity's
scope. The stored `cache_key` is now the raw value the caller sent (the
`vk:` / `raw:vk:` rewriting is gone), so `DELETE
/api/cache/clear-by-key/{cacheKey}` clears every identity's entries
under that key. New `disable_identity_scoping` option (default `false`,
UI switch "Scope Cache by Identity") shares entries across identities
(#8337)
- **Semantic Cache Skips Tool-Call Responses by Default** - Responses
that carry client-executed tool calls (chat `tool_calls`, Responses
`function_call`, `custom_tool_call`, `computer_call`,
`local_shell_call`, `mcp_call`, `mcp_approval_request`) are no longer
written to the semantic cache unless `cache_tool_call_responses` is
`true`. Server-side tool items such as web search are still cached
(#7852)
- **Semantic Cache Response Headers** - Responses that went through a
semantic cache lookup now carry `x-bifrost-cache-*` headers mirroring
`cache_debug`: `x-bifrost-cache-hit` (always sent when a lookup ran),
plus `-id`, `-hit-type`, `-hit-latency-ms`, `-requested-provider`,
`-requested-model`, `-similarity`, `-threshold`, `-provider-used`,
`-model-used` and `-input-tokens` when known. This works on streams and
on the Anthropic, GenAI, Bedrock and Cohere routes, whose bodies have no
`extra_fields` (#8340)
- **Trace Failure Attributes and End-to-End TTFT** - The root span now
carries `bifrost.error.type`, `error.type`, `gen_ai.error`,
`gen_ai.error.code` and the HTTP status, including for requests rejected
before dispatch, and streaming requests get an end-to-end
time-to-first-token attribute that includes queueing, plugins and key
selection (#8404)
- **Raw Payload Export to Connectors** - Connectors can receive the
exact provider request and response bodies. Set `export_raw_payloads:
true` on an OTel profile (or BigQuery) to attach `bifrost.raw_request` /
`bifrost.raw_response` to LLM spans. It requires
`store_raw_request_response` on the provider, is suppressed by
`disable_content_logging`, and drops bodies over 256 KB. Failed requests
export the raw request and the provider's error body. Exposed in the
OTel profile form and Helm (#7391, #7753, #7758, #8227)
- **Per-Connector Attribute Denylist** - New `excluded_attributes` on
OTel profiles (and the Datadog, Kafka, Pub/Sub, Splunk and BigQuery
connectors) drops listed span attributes by exact name, such as
`gen_ai.request.tools`, before export. BigQuery takes column names (for
example `tools`); `trace_id` and `timestamp` cannot be excluded. Unknown
names are ignored (#7754, #7759)
- **Cost Breakdown on Connector Spans** - LLM spans now carry a
per-category cost breakdown under `bifrost.cost.*`
(input/output/additional sides with text, audio, image, cached
read/write, request, reasoning, citation, search queries, guardrail,
MCP, semantic cache and routing). `gen_ai.usage.cost` is still emitted.
Plugins can call `ctx.CalculateCostBreakdown(resp)` for the same split
(#7371)
- **App Label on Metrics** - Requests are classified by `User-Agent`
into an `app` value (`Claude Code`, `Cursor`, `Codex CLI`, `Cline`,
`Windsurf`, `API`, `Other`), exported as the `bifrost.app` span
attribute and an `app` label on request-level Prometheus metrics (#7390)
- **Datadog Metric Dimensions** - New Datadog `metric_dimensions` lists
`x-bf-dim-*` request dimension names to add as DogStatsD metric tags.
Dimensions already reached Datadog spans; metrics stay untagged unless
listed, to bound cardinality (#7389)
- **Lower Tracing Overhead** - Tracing now does only the work attached
connectors read: attribute maps, content summaries and export snapshots
are skipped when no connector is attached, plugin spans are created only
when a connector consumes them, and LLM spans carry a typed payload
instead of an untyped attribute bag. Connectors that predate the new
interfaces still get everything (#7367, #7368, #7369, #7370, #7373)
- **OTel HTTP Semantic Conventions** - The root HTTP span now emits the
stable OTel HTTP attributes `http.request.method` (unknown methods
become `_OTHER` with `http.request.method_original`),
`http.response.status_code`, `http.route` (the matched route template),
`url.path`, `url.scheme` and `user_agent.original`. The deprecated
`http.method`, `http.url`, `http.user_agent` and `http.status_code` are
still emitted (#7810)
- **Response Headers Plugin Hook** - New
`HTTPTransportResponseHeadersHook` runs once, in reverse registration
order, just before response headers are sent, for buffered and streaming
responses alike, so plugins can set headers on SSE streams.
`Content-Length`, `Transfer-Encoding` and `Connection` cannot be changed
and the status code is read-only. Native `.so` plugins may export the
symbol optionally (#7537)
- **Session Grouping in Logs** - The grouped logs view collapses all
requests that share a `session_id` under the session's earliest root
request, with expandable session rows, session totals and a redesigned
expander (tree lines, turn and fallback labels). `GET /api/logs` gains
`group_sessions=true` (requires `roots_only=true`; ignored when
`session_id`, `parent_request_id` or `request_id` is set), and collapsed
rows carry `session_child_count`, `session_total_cost` and
`session_total_tokens` (#7298, #7299, #7300, #7970, #8273)
- **Background Jobs Panel** - New `GET /api/sidekiq/jobs` and `POST
/api/sidekiq/jobs/{id}/cancel` list every pending, running or recently
finished background job (cost recalculation, Warp log indexing) with
progress, and stop one. The notification panel has a Background jobs tab
with count badges, Cancel / Stop job and Clear finished. Access uses
View and Update on `BackgroundJobs` (#7820, #8211, #8275)
- **Exclude Request Types from Object Storage** - New
`logs_store.object_storage_exclude_request_types` lists request types
(the log `object` value, for example `list_models`, `embedding`,
`chat_completion_stream`) whose logs stay in full in the logs database
instead of being offloaded to S3/GCS. Streaming and non-streaming
variants are separate types. Logs with hidden content are still cleared
from the DB row and not uploaded (#8047, #8048)
- **Above-100k Token Pricing Tier** - The cost engine now applies the
datasheet's `*_above_100k_tokens` rates (input, output, cache read, 5m
and 1h cache write) once a prompt exceeds 100,000 tokens, as Claude
Haiku 5.5 bills. Higher tiers (128k, 200k, 272k) still take precedence.
The custom pricing override form has the new fields (#8144)
- **Guardrail Detections** - Guardrail metadata can now record
detect-only policy matches (`detections`: phase, rule, guardrail, reason
and sanitized categories, never the matched text) alongside judge calls.
Docs add the A10 Guardrails integration, regex `allowed_values`, profile
execution order, and the prompt guardrails judge model requirements
(`max_output_tokens` default 1000) (#7697, #7755, #8002, #8410)
- **Unified Provider and Model Selectors** - Every provider and model
picker in the dashboard (provider keys and deployments, CEL builder,
routing rules, pricing overrides, model catalog, limits, caching and
embedding settings, prompts, model access and the add-provider menu) now
uses one `ProviderSelector` and one `ModelSelector`, with icons,
server-side search and paging, multi-select chips and custom-provider
icon fallback. Provider lists in tables collapse into a `+N` chip
(#7247, #7258, #7259, #7272, #7408, #7410, #7427)
- **Entity Picker Infinite Scroll** - Virtual key, team, customer,
virtual MCP and MCP client pickers load further pages on scroll instead
of stopping at the first 20 results, and fetch more when excluded rows
leave the list short (#7678)
- **Responsive Toolbars** - Virtual Keys, Webhooks and provider card
toolbars collapse to icon-only buttons at narrow widths (#7621)
- **Clearer Client Tool Calls in Logs** - A Responses log that ends on a
client-side tool call labels it as a call (not a result), shows "no
arguments" for empty arguments, and links to the next request in the
session that carries the tool result (#7510)
- **Sign-In Redirect on MCP Auth Links** - When
`mcp_enable_temp_token_auth` is off, visitors opening an OAuth consent
or MCP per-user-headers link are sent to `/login` and back instead of
seeing "invalid link". A `401` now carries `error.code`
`temp_token_auth_disabled` or `temp_token_rejected` when relevant
(#7664)
- **Bifrost CLI** - The `bifrost` CLI covers the published API: `api`
(generated catalog of OpenAPI operations with search and tags), resource
commands (`models`, `responses`, `videos`, `providers`, ...), `chat`,
`infer`, `request`/`http`, `context`, `auth`, `usage`, `keys`,
`configure`/`unconfigure` (reversible native-agent setup with receipts
and rollback) and `completion`. It authenticates to the gateway (SSO in
the interactive launcher and authenticated harness launches, with its
own browser auth identity). Output is `--output table|json|yaml|raw`,
and destructive operations require `--yes` (#7279, #7280, #7281, #7282,
#7283, #7284, #7579)
- **Helm Chart 2.1.44** - The chart can now set the config fields added
since 2.1.43, including `proxy_config`, entity `access_profile`, the
`business-unit-data`/`customer-data` scopes, routing `ttft_timeout_ms`,
`storage.configStore`/`storage.logsStore` `statementTimeout` and
`idleInTransactionSessionTimeout`,
`bifrost.client.compat.forceReasoningOnlyModelsToResponses`,
`bifrost.client.deleteExpiredVirtualKeys`,
`bifrost.client.oauth2ServerConfig.allowedRedirectUris`, virtual key
`delete_after_expire`/`disable_content_logging`/`business_unit_id`,
`bifrost.mcp.clientConfigs[].requirePublicTarget`, semantic cache
`cache_tool_call_responses`, object-form routing rule `fallbacks`,
`bifrost.governance.complexityAnalyzerConfig.jev.criteria` and
`bifrost.mcp.toolManagerConfig.maxInstructionsPerClient`/`maxInstructionsTotal`.
New `topologySpreadConstraints` spreads replicas across nodes and zones,
and `extraContainers` adds sidecars (native sidecars go in
`initContainers` with `restartPolicy: Always`, refused on Kubernetes
older than 1.29) (#7791, #8187, #8188, #8189, 0d25eca96)
## ⚙️ Upgrade Notes
These entries change a default, a status code, a response shape or a Go
SDK type. The matching entries above describe each change in full.
- **Agent Gateway (A2A)** - optional; set
`client.a2a_external_client_url` for push and stable card URLs, and
`server.a2a_grpc_base_domain` + `server.a2a_grpc_port` (plus wildcard
DNS) for gRPC. Custom `schemas.Tracer` implementations must add
`ReleaseTrace`.
- **Warp AI Assistant (alpha)** - on by default in OSS; set
`feature_flags.flags.warp.enabled: false` to keep it hidden.
- **Cloudflare Workers AI Provider** - the name `cloudflare` is
reserved; migrate a custom provider named `cloudflare` with the
dashboard dialog or recreate it with `cloudflare_key_config.account_id`.
- **Decisions API in OpenAI Shape** - map-form `/v1/decisions` bodies
are deprecated (still served); update Go SDK code to the new
`BifrostDecisionRequest` fields.
- **Decision Emulation Is Opt-In** - decisions on non-decision models
return `unsupported_operation`; set
`compat.convert_decision_to_responses: true` or send `x-bf-compat:
["convert_decision_to_responses"]` to keep emulation.
- **Multimodal Embeddings** - Go SDK `BifrostEmbeddingRequest.Input` is
now `[]EmbeddingInputItem`; HTTP bodies are unchanged.
- **xAI Realtime** - refusal and content-filter stops are logged as
`model_refusal` errors; exclude that error type from error-rate alerts
if needed.
- **Web Search Priced per Request** - rename
`search_context_cost_per_query` to `web_search_cost_per_request` in
config.json overrides; read counts from
`usage.tool_usage.web_search.num_requests`.
- **Compat: Route Reasoning-Only Models to Responses** - turned on for
existing deployments; set
`compat.force_reasoning_only_models_to_responses: false` to keep the old
behavior.
- **Chat reasoning.mode and reasoning.summary** - the `/openai` chat
route strips `reasoning.summary`; send it through `extra_params` there.
- **Failure Classification and Smarter Key Rotation** - a model missing
on every key returns the provider's `404` instead of `502
upstream_credentials_exhausted`; update alerts on that error and on
`fail_reason` values.
- **Gateway Request ID Header** - read the gateway request ID from
`x-bifrost-request-id`; upstream `x-bifrost-*` headers are no longer
forwarded.
- **Deprecated Models Hidden from Browsing** - add
`include_deprecated=true` to `GET /api/models` to keep deprecated
models.
- **Provider Objects Bound to the Creating Virtual Key** - set
`client.enforce_vk_object_ownership: false` if virtual keys share files,
batches, containers or cached contents.
- **File-Based Batches Under Model-Restricted Virtual Keys** - use a `*`
model grant for OpenAI/Azure file batches, send an allowed `model` for
Gemini/Vertex/Bedrock file batches, and never mix a file with inline
`requests`.
- **Passthrough Route Hardening** - use passthrough only for `POST`
inference paths with rooted paths, the route's own provider and one
string `model` key.
- **Management API Refuses Unlisted Browser Origins** - add cross-origin
browser apps to `client.allowed_origins` or enable dashboard auth.
- **Real Auth Required for Secret References and Private Targets** -
enable dashboard auth or send `X-Bifrost-Setup-Token` for MCP
`env.`/`vault.` references, private webhooks, plugin endpoints, Vertex
`auth_credentials` and `DELETE /api/mcp-logs`.
- **Auth Config Changes Need Proof of Control** - send
`auth_config.current_password` or `setup_token` when re-enabling auth or
rotating admin credentials while auth is off.
- **Request Decompression Limits** - bodies expanding over 100x return
`413`; send them uncompressed or raise
`client.max_request_body_size_mb`.
- **Access Profiles for Teams, Business Units and Customers** - move
config.json limits of governed entities and their keys onto the access
profile.
- **Global Proxy in config.json and for All Outbound Traffic** - set
`enable_for_inference: false` to keep inference direct, and list direct
hosts in `proxy_config.no_proxy`.
- **Audit Logs: Omit IP Addresses** - make SIEM rules accept both audit
`typeURI` values.
- **Attribution Context Keys Deprecated** - read attribution in custom
plugins from `ctx.Grant()`.
- **MCP Client Target Validation at Connect Time** - register private
MCP servers as an authenticated admin or in config.json, and use `http`,
`sse` or `stdio` as `connection_type`.
- **MCP OAuth Server Hardening** - list remote OAuth callback URIs in
`client.oauth2_server_config.allowed_redirect_uris` before upgrading.
- **Virtual Key Rotation Revokes MCP OAuth Grants** - re-authorize MCP
clients after rotating their virtual key.
- **MCP Server Instructions** - bound injected instructions with
`max_instructions_per_client`, `max_instructions_total` or per-client
`max_instructions_length`.
- **Code Mode Execution Limits** - raise fields under
`mcp.tool_manager_config.code_mode_limits` for scripts that exceed the
new budgets.
- **Semantic Cache Scoped by Identity** - expect a cold cache; set
`disable_identity_scoping: true` to share entries across identities.
- **Semantic Cache Skips Tool-Call Responses by Default** - set
`cache_tool_call_responses: true` to keep caching them.
- **App Label on Metrics** - add the new `app` label to recording rules
or alerts that match exact label sets.
- **OTel HTTP Semantic Conventions** - move dashboards to
`http.request.method`, `http.response.status_code`, `http.route` and
`url.path`; the span name and `http.url` drop the query string.
- **Response Headers Plugin Hook** - Go types implementing
`HTTPTransportPlugin` must add `HTTPTransportResponseHeadersHook` (a
no-op is fine).
- **Exclude Request Types from Object Storage** - only exclude request
types whose content you do not need retained in object storage.
- **Helm Chart 2.1.44** - set
`bifrost.client.oauth2ServerConfig.issuerUrl` when `mcpServerAuthMode`
is `oauth` or `both`, or `helm template` fails.
- **Outbound Fetch Redirect Hardening** - test-fire private webhooks
with an authenticated caller; point datasheet URLs at their final
location or use `file://`.
- **Provider base_url Shape Checked** - remove userinfo, query strings
and fragments from `base_url`.
- **Direct Keys Stay on Their Provider** - pass `?provider=` or
`x-bf-model-provider` on direct-key model listings.
- **config.json Governance Limits Reconciled Correctly** - read virtual
key and provider config limits from the key's model configs after the
migration.
- **Partial Provider Key Updates** - send a field explicitly to clear
it.
- **Weights Must Be Valid Numbers** - use weights of 0 or more for keys
and greater than 0 for routing targets.
- **Duplicate Routing Rule Priority Returns 409** - treat `409` as a
request error instead of retrying on `500`.
- **Dashboard Rankings Under DAC** - treat the ranking row `id: "other"`
like `unassigned`.
- **MCP OAuth and Client Fixes** - expect `404`, not `500`, for an
unknown MCP client.
- **Implicit Prompt Caching for gpt-5.6+ Now Takes Effect** - set
`prompt_cache_options.mode: "explicit"` on the request to opt into
explicit mode.
- **Stream Errors Get a Real HTTP Status** - update retry logic and
alerts that assumed every stream error was `400`.
- **Bedrock Incomplete Converse Streams** - truncated Converse streams
now end with `502`.
- **Replicate File List Cursor** - pass the `after` cursor exactly as
returned; others get `400 invalid pagination cursor`.
- **Anthropic Error and Stop Fidelity** - branch on documented Anthropic
error types instead of `api_error`.
- **Error Metrics Report the Real Status** - repoint alerts on
`status_code="unknown"` and add `error_type` to OTel queries.
- **OTLP HTTP Metrics to https Endpoints** - set `tls_ca_cert` or keep
`insecure: true` for self-signed collectors.
- **Connector Export Gaps** - group OTel datapoints by
`bifrost_instance_id` instead of `service_instance_id`, and review
telemetry `custom_labels` for cardinality.
- **Postgres Scale Fixes** - plan IO for the background index build; set
`statement_timeout` and `idle_in_transaction_session_timeout` to `"0"`
to keep server defaults.
- **ClickHouse Large Team Scopes** - set
`logs_store.config.max_query_size` if a ClickHouse settings profile
constrains it.
- **Semantic Cache Vector Store Consistency** - on Weaviate, set
`threshold` to `2 * old - 1` to keep the old hit rate.
## 🐞 Fixed
- **Outbound Fetch Redirect Hardening** - Pricing and model-parameter
datasheets, the MCP library catalog, OAuth2 discovery, registration and
token calls, webhook delivery and the config API URL check now enforce
the private-network dial policy on every connection and redirect hop,
not only the first URL. Failed URL checks on `PUT /api/config` no longer
echo transport details (#7848)
- **Encrypted Session and Virtual Key Lookups** - The legacy plaintext
fallback for sessions and virtual keys now matches only rows stored in
plaintext, so an encrypted row's ciphertext can no longer be used as a
session token or virtual key value (#8302)
- **Virtual Key Header Redacted in Traces** - `x-bf-vk` is now treated
as a credential and redacted in captured request headers, so
observability connectors no longer export it (#8304)
- **Provider base_url Shape Checked** - Provider `base_url` on create
and update must be an origin with an optional path; URLs with
credentials, a query (including a bare `?`) or a fragment are rejected
before anything is stored or dialed (#7958)
- **Direct Keys Stay on Their Provider** - A caller's `x-bf-direct-key`
is no longer sent to every configured provider on an unscoped model
listing, and drop-in routes (`/openai/v1/models`,
`/anthropic/v1/models`, `/genai/v1beta/models`) list only their own
provider. A refused direct key returns the provider's own error (for
example OpenAI's `401`) instead of `502 upstream_credentials_exhausted`,
and no session key binding is created when the direct key serves (#8106,
#8108, #8113)
- **Every Provider Egress Path Uses proxy_config** - Side fetches (image
and document URLs), credential exchanges (Vertex OAuth, Azure Entra ID,
Databricks OAuth) and Bedrock runtime calls now go through the
provider's `proxy_config` instead of connecting directly. `https://`
proxies are reached over TLS (system roots, `ca_cert_pem`, or
`skip_tls_verify`), proxies are dialed dual-stack so IPv6 proxies work,
proxy handshakes are bounded at 30s, runtime proxy changes reach
already-created clients, and `DisablePathNormalizing` is honoured
through the proxy-aware client (#7567, #7569, #7570, #7573, #7576,
#8164)
- **No Shutdown Panic From Request-Scoped Work** - Work started while
serving a request no longer derives its context from the fasthttp
request, which could panic with "missing cancel error" during shutdown
(#8226)
- **config.json Governance Limits Reconciled Correctly** - Budgets and
rate limits declared on a virtual key or provider config in config.json
are now stored on the key's all-models model config tiers, as the rest
of governance expects, and edits to inline budgets (new `max_limit`,
added, removed or moved budgets) apply on reload instead of only at
create. Under `source_of_truth: config.json`, inline budgets and rate
limits on teams, customers, keys and provider configs survive the prune
(a linked inline rate limit no longer stops startup with a foreign key
error), calendar-aligned virtual key budgets keep their alignment after
a restart, and a governed team is no longer saved with its own inline
budgets (#8156, #8161, #8306)
- **Model Limits Match Every Spelling of a Model** - Model config limits
now resolve dated aliases, provider-prefixed, re-cased and padded model
names to the same key on both write and lookup, so one provider-less
limit covers every alias of a model (#7853)
- **Virtual Key Update Keeps Key Associations** - `PUT
/api/governance/virtual-keys/{id}` without `key_ids` no longer sets
`allow_all_keys` to false and detaches every key; an omitted `key_ids`
now means unchanged (#7362) (thanks
[@xiechimon](https://github.com/xiechimon)!)
- **Partial Provider Key Updates** - `PUT
/api/providers/{provider}/keys/{key_id}` now keeps fields left out of
the body (`value`, `weight`, provider configs) instead of resetting
them; fields sent explicitly, even as empty values, are still applied
(#7679)
- **Fallback Usage Billed After a Billed Primary** - Billing dedup no
longer drops a fallback's usage when the primary attempt was already
billed (#8111)
- **Team Calendar Alignment Kept After Restart** - Calendar-aligned team
budgets keep their alignment after a restart (d743fa175)
- **Weights Must Be Valid Numbers** - Negative or non-finite weights on
provider keys and virtual key provider configs, and routing targets with
a weight of 0 or less, are now rejected. Key selection uses float math,
so a bad stored weight can no longer panic a provider worker and tiny
weights are no longer truncated (#8102)
- **Duplicate Routing Rule Priority Returns 409** - Creating or updating
a routing rule with a priority already used in the same scope now
returns `409 Conflict` with the priority and the real scope ID, instead
of `500` with a pointer address (#8104)
- **Session Affinity and Session-Bound Key Fallback** - When a session
is bound to a key the provider rejects outright (credential, quota or
model access), the request moves to another eligible key and the session
rebinds to it, instead of failing with `502
upstream_credentials_exhausted`; keys pinned with
`x-bf-api-key`/`x-bf-api-key-id` still fail immediately. A session no
longer binds to a fallback that served a request sent with the caller's
direct key, no longer moves a request pinned with `x-bf-api-key-id` /
`x-bf-api-key` off the head provider, and drops its binding to a key
removed from a single-key pool (#8100, #8109, #8112, #8384)
- **Caller Errors No Longer Run Catalog-Inferred Fallbacks** - When the
model catalog resolver added fallbacks on its own, a
`400`/`409`/`413`/`415`/`422` from the primary (for example `logprobs`
out of range) is now returned to the caller instead of being answered by
a provider the caller never named. Caller- and routing-named fallbacks
are unchanged. The Gemini raw `generateContent` path now forwards
`logprobs` instead of stripping them (#8434)
- **Fallback Response Headers** - When the primary and every fallback
fail, the primary's error now goes out with the primary's own provider
headers instead of the last fallback's, and a stream answered by a
plugin on a fallback names that fallback in its routing headers (#8107,
#8114)
- **Routing Tree Fixes** - The Routing Tree view now shows more than 100
rules, and its CEL parser handles quotes, escapes and triple-quoted
strings without splitting operators inside string literals (#8173,
#8194) (thanks [@Shashank2985](https://github.com/Shashank2985)!)
- **Complexity Router Keeps Custom Provider Case** - Custom provider
names in the complexity router config keep their case, so a provider
such as `DeepInfra-Embeddings` is found at warmup (#7590) (thanks
[@MohammadHijjawi97](https://github.com/MohammadHijjawi97)!)
- **Complexity Router Classifier Kept on config.json Reload** - A
config.json complexity analyzer block that leaves out the classifier no
longer resets the classifier chosen in the dashboard on a keyword-only
edit. Also fixes a race where abandoning a request delivery could read a
message the worker had already released (#8440)
- **Model Limits List Respects Data Scope** - The paginated model config
list now applies the caller's query scope (#8089)
- **Dashboard Rankings Under DAC** - Under team, business unit or
customer DAC, the Team, BU, Customer and User ranking tabs now group
rows the caller may count but not name into one `Other` row, so each tab
adds up to its total and matches the Overview (#8087)
- **Code Mode Tool Discovery Scoped to the Virtual Key** -
`listToolFiles`, `readToolFile` and `getToolDocs` now show only the
tools the request's virtual key may execute (#7888)
- **MCP Output Guardrails in Code Mode** - Nested tool results in code
mode are logged only after output guardrails run, so blocked or redacted
text no longer reaches the model through the execution log, and error
results go through the plugin pipeline too (#8305)
- **MCP Agent Loop Keeps Earlier Turns** - Auto-executed tool loops now
return content and reasoning from every turn, not only the last, and
follow-up turns reuse the route turn 1 was served on instead of
re-running routing and fallbacks (#8425)
- **MCP OAuth and Client Fixes** - `POST
/api/mcp/client/{id}/reauthorize` returns a `flow_id` and `GET
/api/oauth/config/{id}/status?flow_id=` reports the live flow, so the
consent popup no longer closes on the first poll. OAuth2 `state`,
`scope` and `client_name` columns are `text`, so long values no longer
fail with `server_error` on Postgres. Switching a token exchange client
ID or secret to an `env.`/`vault.` reference is saved instead of keeping
the old plaintext. A client that has not finished admin authorization
stays in `pending_verification` after being enabled, a rejected identity
token in token exchange is reported as rejected rather than missing, and
deleting or updating an unknown MCP client returns `404` (#6926, #7041,
#7051, #7405, #8160, #8436)
- **Implicit Prompt Caching for gpt-5.6+ Now Takes Effect** - v2.2.6
announced implicit prompt caching for gpt-5.6+, but requests carrying
`cache_control` markers (Claude Code on `/anthropic/v1/messages` among
them) to OpenAI, Azure, Bedrock and Bedrock Mantle were still switched
to `prompt_cache_options.mode: "explicit"`, which re-wrote the whole
conversation at the cache-write rate every turn. They now stay in
implicit mode, with the 20-message lookback. Markers still become
`prompt_cache_breakpoint`, capped at three in implicit mode and four
when the caller sets explicit mode (#8322, #8334)
- **Encrypted Reasoning Retry Clears Paired Item IDs** - When an
upstream rejects replayed `encrypted_content`, the strip-and-retry now
also clears the item `id` on messages, function, custom tool, web
search, computer and MCP calls paired with the removed reasoning, so the
retry succeeds instead of failing with `Item 'fc_..' ... without its
required 'reasoning' item` or `404 Item with id 'rs_..' not found` (seen
from Warp on gpt-5.6-luna and load-balanced Azure keys) (#8374)
- **Stream Errors Get a Real HTTP Status** - Mid-stream SSE errors on
OpenAI-family chat, text, speech, transcription and image paths now
carry `429` for rate limits and quota, `400` for context-length errors
and `502` otherwise, Anthropic stream errors map their `type` (including
`529 overloaded_error`), unparseable Gemini stream errors get `502`, and
unexpected key-selection failures return `500` `bifrost_internal`. These
were all reported as `400`, which hid them from 5xx dashboards and
stopped key rotation (#7611)
- **OpenAI Responses Mid-Stream Errors Typed** - A provider error after
a stream has started on `/openai/v1/responses` and the litellm,
langchain, pydanticai and Azure deployment copies is now sent as `event:
error`, as the OpenAI SDKs expect (#8421)
- **Bedrock Incomplete Converse Streams** - A Converse stream that ends
without `messageStop` now returns a `502` error with the event count and
last event type instead of a silent success, with any billed usage
attached (#7797)
- **Truncated Content-Length Streams** - Streams whose body ends before
the declared `Content-Length` are now reported as errors instead of
completing silently, and the incomplete connection is discarded (#8287)
(thanks [@Constantine3](https://github.com/Constantine3)!)
- **Replicate File List Cursor** - The `after` cursor on `GET /v1/files`
for Replicate is no longer used as the next request URL; only its
`cursor` value is kept and requests stay on the configured file
endpoint. Older full-link cursors still work when they point at the
configured endpoint (#8290)
- **Azure Realtime and WebSocket Panics** - An unmapped ephemeral token
on Azure realtime returns `400 invalid_request_error` instead of
crashing on a missing key config, and a panic inside a WebSocket session
(realtime, live, Responses) drops only that connection instead of the
process (#8282)
- **Realtime Sessions Priced** - Realtime WebSocket and WebRTC turns on
models such as `openai/gpt-realtime` now use the `realtime` pricing row,
so log costs and governance budgets are no longer left at zero (#8411)
- **Compat Output Token Fitting on Fallbacks** - With
`should_convert_params` on, the output token cap and thinking budget are
now fitted to the model each attempt actually reaches (fallbacks and
aliased deployments included) instead of once before key selection, and
a lowered cap no longer leaves a thinking budget above the model's own
maximum (for example 65534 on `gemini-2.5-flash`). Each change is logged
in the routing logs (#8242)
- **Anthropic Retargeting to Smaller Models** - When a routing rule or
fallback sends a request sized for a large Claude model to a smaller
one, `max_tokens` is lowered to the target's datasheet ceiling (unless
the `output-300k` beta is on) and `adaptive` thinking becomes `enabled`
with a derived `budget_tokens` on Haiku 4.5, Sonnet 4.5 and Opus 4.5,
instead of returning `400` (#7732)
- **OpenAI Custom Tools on Older Models** - A datash…

Summary
Adds support for Amazon Nova multimodal embedding models (
amazon.nova-2-multimodal-embeddings-v1:0) in the Bedrock provider. Previously, only Titan and Cohere embedding models were supported. Nova uses a distinctSINGLE_EMBEDDINGtask type envelope and supports text, image, audio, and video modalities — including S3-sourced media and combined audio/video vectors.Changes
