Tencent's newsroom post dated 4 November 2026 announces Tencent Hy4. It says the model adds visual understanding for the first time, including fine-grained image processing, chart analysis and mathematical visual reasoning, and adds computer use for the first time, on both command-line and graphical interfaces. It says the model was trained on professional software such as Blender and CAD. It says Hy4 is available on Tencent Cloud TokenHub, WorkBuddy, CodeBuddy, Yuanbao, WeCom's AI Assistant (Dayuan), ima and other Tencent products, and that the API is being made available on OpenRouter, Hermes and OpenCode. It says model weights and system cards are planned for the coming days. They are not in this post.
The post says the price is unchanged from Hy4 Preview: approximately US$0.90 per million input tokens, US$2.70 per million output tokens and US$0.045 per million cached input tokens. It says WorkBuddy and CodeBuddy will be available for free from 4 to 15 November, and that Hy4 on Tencent Cloud TokenHub is 50% off its standard pricing through 31 December 2026. A heading on the same page says "Hy4 Flash Recently Released". The paragraph under it says Hy4 Flash is scheduled for release soon. This story follows the paragraph.
The post says offensive materials related to exploitation are excluded from the training data, and that assessments by Tencent's Xuanwu Lab and Keen Security Lab found no significant concerns about offensive cybersecurity capabilities in the areas they evaluated. It says internal expert reviews found strong foundational biological knowledge and more limited open-ended experimental design than frontier models. Those are Tencent's statements.
Tencent Cloud's Hy API guide, last updated 2026-11-04 12:10:59, lists the model id hy4 with a context window of 1M, a maximum input of 960k and a maximum output of 64k, and says it introduces visual understanding for the first time. The guide does not state a parameter count. The newsroom post does not either.
What it means for business: Hy4 can be called as a hosted model now. The weights are not in the post. The dollar figures are the newsroom's approximate prices, and the 50% TokenHub discount runs through 31 December 2026. This describes the posts. It is not advice on a particular system.
