Tencent unveils new AI models with enhanced vision capabilities

On October 29, 2026, Tencent announced during its global digital ecosystem conference that it will soon release the Hy4 AI model. The model represents a significant upgrade from its preview version, Hy4 preview, with enhanced capabilities for long-range and real-world productivity tasks. It also introduces visual understanding for the first time. The Hy4 flash model is set to launch soon, offering a high-performance-to-cost ratio. It builds on Hy4's visual and agent capabilities through deep integration of model and product design. Earlier in August 2026, Tencent launched Hy4 preview with 770 billion parameters, 49 billion active parameters, and a 1 million token context length. The model showed improvements in size, context length, and data scale, with enhanced pre-training and post-training processes leading to a significant leap in intelligence.
