| What’s different | Hy4 preview is a 770B-parameter Mixture-of-Experts flagship model from the Tencent Hy Team, with 49B parameters activated per token and a 1M-token context window. It uses Gated DeepSeek Sparse Attention… | Small decision model for routing and scoring; the Workers AI route currently reads only roughly the first 2K text-state tokens. | Always-on adaptive thinking defaults to medium effort; built for sustained work across large codebases and professional documents. |
