Tether released 800 million parameter edge AI model BotPsy

According to Tether's official announcement, Tether AI Research has released the open-weight model QVAC BotPsy, which has 800 million parameters and is based on the Alibaba Qwen3.5 architecture, aimed at tool invocation and agent tasks on personal devices.

Tether stated that in four evaluations: BFCL v4, ACEBench, τ-bench, and ToolSandbox, BotPsy's scores are approximately twice that of its base model and surpass the 2 billion parameter Qwen3.5-2B-Think. The model can convert user requests into local tool calls, and developers can adapt and deploy its weights within their own systems.
