Tether AI Research introduces BotPsy, a 0.8B on-device tool-calling model based on Qwen3.5-0.8B
Hugging Face Blog published this on Nov 11, 2026 (source: huggingface.co).
In a Hugging Face post published 11 November 2026 at 05:01 UTC (00:01 ET), Tether AI Research introduced BotPsy, a 0.8-billion-parameter model for function calling and agentic workflows, built on Qwen3.5-0.8B and intended for on-device use on low- to medium-difficulty tasks. Benchmark figures, including results versus models up to 1.2B and some comparisons with Qwen3.5-2B-Think, are the authors' own evaluations and do not establish that it comprehensively outperforms 2B-class models. The post describes a tool-use model, not a shipped complete personal-assistant application.
