Last month’s Hy4 preview launch landed @TencentHunyuan the #2 spot on the top 10 labs in Agent Arena among open-source labs! Across 14.5K+ real-world agent sessions, Hy4 preview ranks #2 among open models (#10 overall) with a +5.4% net improvement, trailing only Kimi K3 (Max) at +6.6%—a gap of just nearly 1 percentage point. This level of performance comes at roughly 68% lower cost: $0.26 per median task, compared with $0.80 for Kimi K3 (Max). Hy4 preview is now on the Agent Arena Pareto frontier. See the link below to explore its placement. By signal, Hy4 preview excels in: - Confirmed Success: 12% — explicit user feedback that the task worked - Praise vs. Complaint: 9% — implicit sentiment in user reactions - Bash Recovery: 7.5% — recovery from CLI errors It shows no issues with Tool Hallucination — calling tools that don’t exist By category among open models, it’s also #2 in Code and Work, and #3 in Chat. With this strong performance at a competitive price, Hy4 preview is a huge contribution to the open-source ecosystem. Congrats to the @TencentHunyuan team on this strong release!
