Today we're releasing Trinity-Large-Thinking. Available now on the Arcee API, with open weights on Hugging Face under Apache 2.0. We built it for developers and enterprises that want models they can inspect, post-train, host, distill, and own.

Preview showed us where the demand was going. People were already running Trinity-Large-Preview in real agent workflows, with long-horizon tool use and production constraints. So over the last two months, we pushed our SFT and RL stack to meet that moment.

Our focus was clear. Build a model that stays coherent across turns, uses tools cleanly, follows instructions under constraint, and is efficient enough to serve at scale. That is the bet behind Trinity-Large-Thinking.

The benchmark picture reflects that bet:

More important than any one score, Trinity-Large-Thinking is a major step up from Preview in the places that matter most for agents: better multi-turn tool use better context coherence cleaner instruction following more stable long-running behavior

Shoutout to @OpenRouter, @digitalocean, @huggingface, @datalogyai, and @PrimeIntellect. Great models need great distribution, great data, and great infrastructure. We are grateful to be building with partners who understand that.

Trinity-Large-Thinking from Arcee: Apache 2.0 license, a 400B-parameter sparse Mixture-of-Experts with 13B active parameters. 128k/256k context window, 80k max output tokens. Very cheap API pricing: $0.25/M input tokens and $0.90/M output tokens. Text-only. I need to test this!

The US needs this. I work with agencies who need elite, trustable (read not Chinese) custom models to run in their higher impact level environments. Awesome work!
