Tool use with a small model
Introduced on November 11, BotPsy is a 0.8-billion-parameter model built on Qwen3.5-0.8B. It is designed for on-device assistants using tools such as web search, files and calendars.
Model weights and GGUF packages at different precisions are available. The researchers position the model for tasks of low to medium difficulty.
Assess results in light of model size
The team reports better tool-use results than the base model in its own tests. It also explicitly notes that this small model can make mistakes and is not designed for high-risk use. Applications must separately restrict tool permissions.
