Tencent opens Hy3 globally via WorkBuddy, Miora and TokenHub

Tencent's August 5 post is about access rather than a new model. Hy3, which Tencent released on July 6 as open weights under the Apache 2.0 license, could already be downloaded and run by anyone with the hardware. This announcement puts it inside three hosted Tencent products that international users can sign up for. According to Tencent's launch announcement, Hy3 is a mixture-of-experts model, a design that holds 295 billion parameters but uses only 21 billion of them for each token, with a context window of 256K tokens.

The three routes serve different users. WorkBuddy is an agent workspace for research, data analysis, documents, presentations and office messages, with more than 100 built-in skills and remote control through Discord, Slack and Telegram; Tencent made it free for international users until August 31, 2026. Miora is a design workspace that coordinates several specialized agents to turn a plain-language request into graphics, video, 3D content or interface designs. TokenHub is Tencent Cloud's developer gateway, one API for Tencent's own Hy models and third-party models. Its product page, which now also lists the later Hy4 preview, names DeepSeek, GLM, Kimi, MiniMax and Qwen among those third-party models and offers pay-as-you-go billing, guaranteed resources or dedicated deployment.

The performance claims are Tencent's own. The company says Hy3 rivals flagship models two to five times its size and that, in internal tests, WorkBuddy running on Hy3 completed more than 90% of tasks and finished them in 34% less time than with the previous Hy model, but it does not name the tasks or comparison models. The one concrete price it gives is on OpenRouter, from US$0.1288 per million input tokens and US$0.5336 per million output tokens. For anyone choosing between these routes, the practical difference is that the hosted products remove the need to serve a 295-billion-parameter model yourself, at the cost of relying on a hosted service and on performance claims Tencent has not shown how to check.
