Tencent releases Hy4 with vision and computer-use capabilities

Tencent announced the full release of Hy4 on November 4, 2026, describing it as a major advance over the earlier Hy4 Preview. The model adds visual understanding and computer-use capabilities (CLI and GUI) for the first time, along with reported gains in instruction following, long-context handling, and long-horizon agentic tasks. It is available via Tencent Cloud TokenHub, OpenRouter, and internal products such as WorkBuddy and CodeBuddy, with weights and system cards planned for release shortly. Pricing remained unchanged from the preview with a temporary discount. The release strengthens Tencent’s position among leading open-weight models with multimodal and agent features.
