Tencent announces Hy4 multimodal model availability in products and cloud while promising future open weights

Tencent's 4 November 2026 corporate announcement says its Hy4 multimodal model service is available in Tencent products and cloud APIs, with capabilities including tool use and computer interaction. At the time of the announcement, the company stated that downloadable weights and system cards would be released in coming days. This event records service availability as announced, not completed release of model weights or independently verified model benchmark rankings. Corrects Post-Cutoff's earlier misleading title without inventing a second open-weight milestone.
