Why we picked it

腾讯混元的 Hy4 在 Atlas Cloud 上线 API 了，官方演示让它看《星夜》再自查渲染结果，几轮迭代后输出一个单文件 HTML 的 3D 世界。做 3D 生成或多模态应用的开发者可以看看这个新入口。

腾讯混元 Hy4 的 API 现已在 Atlas Cloud 平台上线，开发者可以直接调用。Atlas Cloud 用梵高《星夜》做了演示：Hy4 先看到原画，随后接收自己渲染结果的截图，将其与原画逐轮比对修正。经过几轮迭代后，它产出了一个可进入浏览的 3D 世界，且全部打包在单个 HTML 文件中。

这个演示重点展示了 Hy4 的多模态能力——"Hy4 can see now"意味着模型具备视觉理解，能把生成结果截图回传给自身做视觉校验，形成渲染-检查-修正的闭环工作流。相比以往只能盲改的生成流程，这种视觉反馈机制能显著减少 3D 场景与参考图的偏差。

对开发者而言，Hy4 API 上线 Atlas Cloud 意味着腾讯混元的模型部署渠道进一步扩展到第三方云平台，做 3D 世界生成、多模态内容创作的团队多了一个可选的调用入口，不必仅依赖腾讯自家渠道。

Hy4 API is live on Atlas Cloud Atlas Cloud @atlas_cloud_ai @TencentHunyuan Hy4 - API is now live on Atlas Cloud! Hy4 can see now.💙 We gave it Van Gogh's The Starry Night, then sent back screenshots of its own renders so it could check them against the painting. A few rounds later, it shipped a 3D world you can step into. One HTML file.

Tencent Hunyuan Hy4 tops Agent Arena as best Chinese model

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.

Tencent Hunyuan's Hy4 tops APEX-Agents open-weights leaderboard

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.
