Arcee AI

Arcee AI builds open-weight foundation models optimized for deployment anywhere—edge, on-prem, or cloud. The company began in post-training before moving upstream to pre-train their own models, producing the Trinity family of foundation models released under Apache-2.0. Backed by investors including Emergence Capital, Samsung, M12, and Hitachi Ventures, Arcee focuses on performance per parameter and maintains a commitment to open-weight R&D.
