# Tencent releases Hy4 with visual understanding and computer-use capabilities Tencent Tencent released the final Hy4 model on November 4, 2026. Compared with Hy4 preview from August 28, the final release adds visual understanding and computer-use capabilities, combining command-line and graphical-interface actions while strengthening long-context, long-horizon and complex workflows. The official model list specifies a 1M-token context, up to 960k input tokens and 64k output tokens. Tencent says Hy4 is live on Tencent Cloud and OpenRouter and can be used through WorkBuddy/CodeBuddy, Yuanbao and ima. TokenHub uses the model ID hy4 and requires a Tencent Cloud account, TokenHub activation and an API key. Account and regional availability depend on each product's actual access conditions. TokenHub's pay-as-you-go list prices are CNY 6 for input, CNY 18 for output and CNY 0.3 for cache-hit tokens per million. From publication of the pricing notice through December 31, 2026 at 23:59:59 Beijing time, Hy4 usage incurred within the offer period is charged at 50% of list prices; list prices resume afterward. This is not a discount on Token Plan subscriptions, and identical pricing across all regions has not been verified. Open weights for the final model remain planned, and Hy4 flash is a future release. The preview's open-weight status and 770B/49B parameter counts are not carried over as facts about the final model. The older preview record remains unchanged. ## Availability Available on Tencent Cloud TokenHub and OpenRouter, with access through WorkBuddy/CodeBuddy, Yuanbao and ima. TokenHub API access requires a Tencent Cloud account, service activation and an API key. Open weights for the final release are planned, not yet confirmed available. - Released: Nov 04, 2026 - Review updated: Nov 04, 2026 15:20 Wed ยท Beijing Time (UTC+8) ## Sources - Source excerpt: https://hunyuan.tencent.com/research/hy4?langVersion=zh - Source excerpt: https://cloud.tencent.com/document/product/1823/130055/ - Source excerpt: https://cloud.tencent.com/document/product/1823/132252 - Source excerpt: https://cloud.tencent.com/document/product/1823/130675 Canonical entry: https://www.ailyre.com/source/?id=tencent-hy4&lang=en
