Tencent has released a preview of its Hunyuan Hy3 model, its first major AI update since hiring former OpenAI research scientist Yao Shunyu. The model brings improvements in complex reasoning and coding. Separately, DeepSeek announced its V4 Flash and V4 Pro Series, featuring advances in reasoning, agentic tasks, and a new Hybrid Attention Architecture for better long-context memory. Both releases reflect China's accelerating push to compete with US AI developers through open-source and proprietary models.
