Tencent launched vision and computer-use capabilities for its flagship Hunyuan Hy4 model on November 4, enabling it to interpret charts and documents, reason across multiple images, and operate command-line tools and graphical interfaces on its own. The preview version released August 28 was text-only, a 770-billion-parameter mixture-of-experts system built for coding and office work. Tencent shipped Hy4 as API-only and said the model weights and system card would be released later, notable because the August preview was released under an Apache 2.0 license with downloadable weights on Hugging Face. Hy4 is available through Tencent Cloud's TokenHub, OpenRouter, and Tencent's WorkBuddy and CodeBuddy products, with a free usage quota from November 4 through November 15, after which it is priced at $0.834 per million input tokens and $2.501 per million output tokens; TokenHub also carries a 50% discount through the end of December. Training focused on office tasks, financial analysis, and game development, including operating software like Blender and CAD tools. On an internal finance evaluation covering 579 real-world tasks, Tencent says Hy4 scored 3.04 against DeepSeek-V4.1-Flash's 2.97, and reported gains of 19.1% on its GameDev benchmark and 9.8% on GameLogic. Tencent says its internal search evaluations showed Hy4's hallucination rate
