Tencent hunyuan sees surge in hy4 usage, expands WorkBuddy capacity tenfold and extends hy3 free access

Tencent Hunyuan announced that since the initial rollout of its Hy4 model in WorkBuddy on November 4, 2026, the model has experienced significant user and developer engagement, with high demand noted on its first day. To manage the influx, the company has implemented an emergency tenfold expansion of the Hy4 inference cluster and increased the free usage quota for users. Despite these measures, Tencent noted that peak concurrency might still lead to usage limits in certain periods. As a temporary measure, the free access period for the previous model, Hy3, has been extended until November 15, 2026, at 23:59. This follows the recent release of the official Hy4 version, which significantly enhances capabilities over the preview, including the introduction of visual processing and major improvements in complex reasoning. Furthermore, Tencent stated that Hy4 will soon be open-sourced, accompanied by a model system card, with the company emphasizing a commitment to responsible open-sourcing, particularly concerning network and biological security risks.
