I can’t help rooting for tiny open source AI model maker Arcee

Arcee, a 26-person U.S. startup, released a new reasoning model called Trinity Large Thinking.

Trinity Large Thinking is an open-source LLM with 400B parameters, released under the Apache 2.0 license.

Benchmark results show Trinity is comparable to some of the top open-source models.

Arcee offers both on-premises deployment and a cloud-hosted API for the model.

OpenRouter data ranks Trinity among top models used with OpenClaw; Anthropic subscriptions no longer cover OpenClaw, so users must pay additionally.
