The language model family fired by TheColliery.
Kolwen carries TheColliery's engineering discipline—measured-not-trusted, honesty over polish, safety rails by construction—into models meant to be run by their users. None has shipped yet.
None of these models has shipped. The table names the seat each is meant to fill; nothing is downloadable yet, as the Status section says.
| model | intended seat |
|---|---|
| Kolwen | planned: a free model with open weights to run yourself; not released, no date set, nothing on sale |
| Kolwen Peat | smallest of the fired line |
| Kolwen Lignite | the workhorse |
| Kolwen Anthracite | the top—highest-grade coal, hottest and cleanest burn |
The names follow the coalification series: peat → lignite → (sub-bituminous) → bituminous → (semi-)anthracite. Kolwen names four ranks; the bracketed grades are seams, not tiers. Bituminous is a named rank with no model behind it yet—reserved, not shipped.
Pre-release. Nothing is downloadable yet. This repository is the product's public face—documentation, releases, and community—in the same shape as anthropics/claude-code: the kitchen is not here.
- Planned to be built on Qwen (Apache-2.0 base)—base attribution will ship with every release.
- No model weights have been released and no release date is set. If and when weights are released, each release will carry its own license.
- Issues and pull requests are welcome now—see CONTRIBUTING.md, which asks you to open an issue first.
