Arcee AI Trinity Large Thinking: one model, one job

Arcee AI contributes Trinity Large Thinking, a reasoning model priced at $0.25 input and $0.80 output per 1M tokens — unusually low for a model built around deliberation.

Arcee works on model merging and distillation, producing compact models that inherit capability from larger ones. If reasoning at volume is the requirement, this is one of the cheapest ways to get it.

• Benchmark against a comparable model from a larger vendor before committing production traffic — line-ups this size get less independent testing.
• Start with Trinity Large Thinking at $0.25 / $0.8 per 1M tokens; it is the cheapest entry point here.
• Check the context window against your longest input — the largest here is Trinity Large Thinking at 262.1K tokens.
• Confirm support terms and deprecation policy, which smaller vendors document less thoroughly.
