LLMs · RAG · Agents · Voice AI · Multi-provider orchestration
- RAG & retrieval — hybrid BM25 + dense, query rewriting, RRF fusion, evaluation
- Agents — ReAct, multi-agent pipelines, structured extraction, tool use
- Voice AI — phone-based LLM agents on telephony, async webhooks, post-call analysis
- LLM infrastructure — multi-provider orchestration (GPT-4o, Claude, Gemini) with automatic fallback and cost controls
