腾讯混元跻身最强开源模型！一手实测Hy4：搭配WorkBuddy，多模态Agent交付力拉满
腾讯把混元 Hy4 开源了，我实测配 WorkBuddy 跑多模态 Agent 任务，交付效果相当能打，感兴趣可以看看实测细节。
腾讯混元发布并开源了 Hy4 模型，实测中可与 WorkBuddy 搭配使用。该模型主打多模态能力，在 Agent 任务交付场景中表现突出。文章作者进行了第一手实测，展示了其在多模态 Agent 场景下的实际表现。
LMArena 这周榜单很热闹：Kimi K3.1 Pro 开源拿下 Agent 第一，腾讯 Hy4 成本才 $0.57，Gemini 视频、OpenAI 图像都有新作，一条看全。
Cost-per-task of US$0.57 with top-5 agentic performance makes Hy4 a strong price-performance option for agent workloads. Developers evaluating Chinese alternatives to US frontier models can compare it directly on Agent Arena's session-based leaderboard. The model is relevant to ASEAN teams building on Tencent's ecosystem, where Hunyuan integration is already common.
腾讯 Hunyuan 的 Hy4 在 OpenDesign 设计基准排第 4，只差 GPT-6.1 Sol 0.1 分，成本还低 41%，做设计的可以看下榜单。
The gap between Hy4 and the next open-weights model is nearly 8 points on Pass @1, which resets assumptions about where free-weights agent performance stands relative to closed models. Teams selecting models for professional-work agents—consulting, finance, legal workflows—can use the Mercor APEX-Agents leaderboard to shortlist candidates by domain rather than headline scores. Comparisons against Kimi K3.1 Pro and Qwen3.8-Max make it a practical benchmark for China open-weights options.
The upgrade comes from post-training and perception rather than scale, which means the same 770B base now handles screenshots, charts and full desktop workflows — a shift that matters more for agent builders than raw leaderboard chasers. Missing third-party evaluations mean teams should run their own tests before switching, and the free quota until 15 Nov 2026 makes a hands-on comparison against DeepSeek or Qwen low-cost to attempt.
腾讯混元 Hy4 冲到 Agent Arena 中文第一，单任务成本比 Kimi K3.1 Pro 便宜六成多，分数还几乎持平，跑智能体任务可以试试它。
