Tencent expanded the Hy4preview inference cluster after the model’s WorkBuddy debut triggered heavy demand and queueing. The company also extended limited-time free access to Hy3 and other existing models through September 30, 2026, while warning that peak-time queues may recur.
Tencent has released WeMM-Embedding, a family of 2B, 4B, and 9B universal multimodal embedding models. The models support text, images, videos, visual documents, and interleaved inputs, and are trained through alignment and refinement stages. Tencent reports that the 2B variant beats a leading 8B open-source baseline on MMEB-v2, while the 9B model achieves an overall score of 80.6. The models also showed gains in internal evaluations and 14 online A/B tests, and are deployed across WeChat search, recommendation, content, and e-commerce applications. Model weights and code are available publicly.
