Overview
- Tether announced QVAC BotPsy on Wednesday, November 11, 2026, releasing an open‑weight 0.8‑billion‑parameter agent fine‑tuned from Alibaba’s Qwen3.5‑0.8B.
- Tether reported BotPsy posted a mean score of 45.0 across six agentic tool‑use benchmarks and said it beat models up to 2.5 times its size on most tests.
- The company highlighted large gains versus its base model on specific tests, including BFCL v4 rising from 23.4 to 44.0 and τ‑bench reaching 51.5, which focus on function calling and tool selection.
- Tether distributed BotPsy in GGUF format under an Apache 2.0 license and framed the release as research and education software best suited to low‑to‑medium difficulty, on‑device tasks.
- Journalists note the results come from a focused six‑test scorecard rather than broad evaluation, so independent testing is needed to confirm real‑world performance and the wider implications for moving assistants off the cloud.
