Tether AI Research introduced BotPsy, a 0.8-billion-parameter model for calling tools and running workflows on a device. It is based on Qwen3.5-0.8B and is being released with open weights for research and education. The team says it led five of six tool-use benchmarks among tested models with up to 1.2 billion parameters, while acknowledging limits in open-ended search, difficult tasks, and lower-resource languages.

Why it matters

A small agent that runs locally could lower costs and keep more data on the device, but its authors rule out safety-critical or sensitive decision-making uses.

For the technical crowd

BotPsy is available in safetensors and GGUF formats at bf16, Q8, and Q4 precision. In the team's reported tests, it scored 44.0 on BFCL v4, compared with 23.4 for the base model.
