Notice on the Offline of Hunyuan Image Generation 3.0 Models
Both Hunyuan image generation 3.0 models — HY-Image-3.0-Plus-4090-Tob-v1.0 (text-to-image) and HY-Image-v3.0-I2I-ToB-v1.0.1 (image-to-image) — will be taken offline at 00:00 on December 1, 2026. Calls will fail after that time.
The replacement, hy-image-v3.5-preview, will be available in mid-November 2026. The new model is called differently from the Hunyuan image generation 3.0 models. The specific code changes will be communicated later. Estimate the effort and reserve time for adaptation.
