About
Unisound U2 is a native agentic large language model announced June 8, 2026, by Chinese AI company Unisound (云知声). Designed for multi-step autonomous task execution, it uses native reasoning-path distillation for task decomposition, execution, verification, and optimization. The official Token Hub page lists a sparse MoE architecture with 266B total parameters and 10B active parameters, plus API access through Unisound Token Hub. Emphasis is on coding, tool orchestration, and long-horizon agent workflows. Unisound self-reports GPQA Diamond 87.9, SWE-bench Verified 75.0, and Claw-Eval 76.9; treat those benchmarks as vendor-reported until independently verified. Context window is not disclosed.
Unisound U2 is a proprietary model. The structured metadata tracks reasoning, function calling, and tool use. This page tracks provider routes through Unisound Token Hub. Headline tracked benchmarks include Google-Proof Q&A 87.9 and SWE-bench Verified 75.0.
