[Tether Releases 800 Million Parameter Edge AI Agent Model BotPsy] According to a report by DeepFlow TechFlow on November 11th, Tether AI Research released the open-weight model QVAC BotPsy. This model boasts 800 million parameters, is based on Alibaba's Qwen3.5 architecture, and is designed for tool invocation and agent tasks on personal devices. Tether stated that in four benchmark tests—BFCL v4, ACEBench, τ-bench, and ToolSandbox—BotPsy scored approximately twice as high as its base model and surpassed the 2 billion parameter Qwen3.5-2B-Think. The model can translate user requests into local tool invocations, and developers can adapt and deploy its weights within their own systems.
