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 | the free model—open weights, run it yourself |
| 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.
- Built on Qwen (Apache-2.0 base)—base attribution ships with every release.
- Model weights, when released, carry their own license per release.
- Issues and pull requests are welcome now—see CONTRIBUTING.md, which asks you to open an issue first.
