Strengths & weaknesses

Strengths

  • Tool calls hold their shape across third-party agent scaffoldings instead of needing harness-specific patches
  • Recovers from a failed tool call rather than looping on it — the reliability bug Tencent set out to fix after the preview
  • Reasoning is a per-request switch, so quick answers and deep work come off one endpoint
  • Apache 2.0 with no regional carve-outs, unlike the Hunyuan releases before it

Weaknesses

  • Answers confidently where it should abstain — third-party knowledge probes catch it fabricating far more often than Tencent's own hallucination figures suggest
  • Text-only: no images, screenshots or documents
  • Thinks at length on high effort, so agentic runs consume far more output budget than the token price implies

Successor to April's Hy3 Preview; the licence moved to Apache 2.0 with this release. GPQA Diamond 90.4, SWE-bench Verified 78.0 and Terminal-Bench 2.1 71.7 are Tencent's own figures, published as an image and transcribed by launch coverage — Artificial Analysis independently measures GPQA 89.7 and Terminal-Bench 2.1 64.4. HLE 31.6% is Artificial Analysis' no-tools run; Tencent reports 53.2% with tools. Also reported: SWE-bench Pro 57.9%, SWE-bench Multilingual 75.8%, DeepSWE 28.0%, and a blind 270-expert evaluation at 2.67/4. MMLU-Pro, AIME and ARC-AGI-2 were not published. Pricing is the OpenRouter listing — Tencent publishes no first-party per-token price sheet. Speed is Artificial Analysis' median across providers serving Hy3, not a first-party Tencent endpoint measurement.
