arena · x · 2026-07-22
Tencent’s Hy3 lands at #5 among open-weight models in Agent Arena and is also #2 among open models in Frontend Code Arena.
What the benchmark says
- Overall Agent Arena rank: #25 with -2.2% net improvement.
- Strength: tool use, especially recovering from CLI/bash errors.
- Weakness: steerability — it struggles to course-correct when users push back.
- The benchmark runs on millions of real-world long-horizon agent tasks, including web search, filesystem, terminal, slide decks, app building, and document analysis.
The result positions Hy3 as a strong open model for agentic workflows, but not a leader on overall user satisfaction or steerability.
