Arcee AI is moving its Trinity model family to OpenMDW-1.1, a license intended to cover the different materials supplied in an AI release together. Those materials can include model weights, configuration, code, and documentation, which developers often use as one package.
In its May 29, 2026 announcement, Arcee says the change includes previously released Trinity models and their quantizationShrinking a model by storing its numbers less precisely — like rounding — so it runs faster and fits on smaller hardware, at a small quality cost.Full definition → variants. It also says modification, self-hosting, and commercial deployment remain permitted without a separate commercial license. The stated purpose is to make the terms more consistent across the family and its distributed materials.

quantization — Shrinking a model by storing its numbers less precisely — like rounding — so it runs faster and fits on smaller hardware, at a small quality cost.
eval — A repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.
