Trinity Nano Preview

arcee-ai

Released: December 1, 2025
Data date: September 26, 2026

Trinity Nano Preview is the small experimental Trinity variant with 6 billion total parameters and about 1 billion active parameters. Arcee documents a 128K context, chat tuning, and only about 800 million active non-embedding parameters per token. The model card warns about instability in some uses and explicitly says this Preview will not be hosted, so it is intended to be downloaded and run locally.
