Tether AI Research posted BotPsy on Hugging Face on Nov. 11: a 0.8B-parameter, Qwen3.5-based model for on-device function calling, to be released with open weights under Apache 2.0 for research and education. It lifts BFCL v4 from 23.4 to 44.0 over its base. Authors say it suits low to medium difficulty tasks and is weak at multi-step retrieval.
