Stablecoin issuer Tether's AI research arm has released BotPsy, a 0.8B-parameter agent model small enough to run on a phone, built on Qwen3.5-0.8B.
Per Tether's published benchmarks (thinking mode), BotPsy strongly outperforms its base model on tool-use evals: BFCL v4 44.0 vs 23.4, ACEBench 58.7, τ-bench 51.5, and ToolSandbox 64.6 — the last beating even the 2B Qwen3.5-2B (41.2). It still trails Qwen3.5-2B on Claw-Eval (46.5 vs 48.9) and MMLU-Pro (48.9 vs 65.5).
