Arcee

Arcee AI is a U.S. model lab led by builders. We began in post-training, then moved upstream to pre-train our own models because we believe progress won’t be defined by size, but by efficiency, adaptability, and the ability to own what you build. Arcee AI builds open-weight foundation models that run anywhere - edge, on-prem, or cloud, so builders keep control. Our Trinity family standardizes capabilities across sizes and is released under Apache-2.0. What you adopt today runs tomorrow.
