Arcee Releases Trinity Large Thinking Model

Arcee, a 26-person U.S. startup that trained a 400B-parameter open-weight LLM on a reported $20 million budget, on April 7 released Trinity Large Thinking, a new reasoning-focused model. The model is available for download and via API under an Apache 2.0 license; benchmarks show it rivals leading open models but does not yet surpass closed-source giants, offering on-premise sovereignty options.
Scoring Rationale
Timely product release of a notable open-weight 400B-parameter reasoning LLM with direct usability and strong relevance. Scored high for novelty, actionability, and core relevance; adjusted modestly because claims rely on single-source benchmarks and do not yet overtake closed-source leaders.
