Hy4 正式发布，为真实生产力而生
Tencent Hunyuan has officially released Hy4. Compared to its preview version, the model significantly scales up both pre-training and post-training while introducing vision and computer-use capabilities. Specifically optimized for complex interactive development, real-world financial scenarios, and end-to-end scientific research, its hallucination rate drops to 5.45% in internal benchmarks. It was also co-developed alongside the single-cell representation model HyCell and the physics foundation model HyPDE. Hy4 is now live on Tencent Cloud and OpenRouter and integrated into products such as Yuanbao and ima, with plans to open-source its weights and launch Hy4 Flash in the future.
The original article details benchmark data and deployment results across multimodal, computer-use, financial, and scientific research scenarios, helping developers assess the viability of open-source large models in actual production workflows.
