The language model family fired by TheColliery.
Kolwen carries TheColliery's engineering discipline—measured-not-trusted, honesty over polish, safety rails by construction—into a model you can actually run.
| model | 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 discussion welcome once the first release lands.
contact@kolwen.com—for anything that does not belong in a public issue. Once the first release lands, bugs and feature discussion belong in Issues.
