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, is now available, and the image generation credits from the Growth Plan can be deducted directly on it. The new model is called differently from the Hunyuan image generation 3.0 models. For migration, see Hy-Image-3.5-preview. Please complete the adaptation before the offline date.
