🚀 **Tencent Hunyuan Hy4 is live on APIYI at \$0.85 input / \$2.55 output per 1M tokens**

Tencent released the Hy4 formal version on November 4: 770B MoE with 49B active, a 960K input window and 64K output, and for the first time vision understanding and Computer Use in one model. `hy4` is available in the `Default` and `SVIP` groups through the OpenAI-compatible `/v1/chat/completions` endpoint, with cached input at \$0.045 per 1M tokens; office tasks pass at 96.15%, finance crowdsourcing ranks first among open models, and the hallucination rate falls from 12.95% to 7.2%.

Vision input is confirmed working: pass images directly in `messages`. Computer Use is a new upstream capability — validate it with a single request in your own format before relying on it.
