Z Image Turbo Fun Controlnet Union 2.1 EU AI Act Compliance Profile

Z-Image-Turbo-Fun-Controlnet-Union-2.1

Update

• [2026.02.26] Update to version 2602, with support for Gray Control.
• [2026.01.12] Update to version 2601, with support for Scribble Control. Added lite models (1.9GB, 5 layers). Retrained Control and Tile models with enriched mask varieties, improved training schedules, and multi-resolution control images (512~1536) to fix mask pattern leakage and large control_context_scale artifacts.
• [2025.12.22] Performed 8-step distillation on v2.1 to restore acceleration lost when applying ControlNet. Uploaded a tile model for super-resolution.
• [2025.12.17] Fixed v2.0 typo (control_layers used instead of control_noise_refiner), which caused double forward pass and slow inference. Speed restored in v2.1.

Model Card

a. 2602 Models

| Name | Description | |--|--| | Z-Image-Turbo-Fun-Controlnet-Union-2.1-2602-8steps.safetensors | Supports multiple control conditions (Canny, Depth, Pose, MLSD, Hed, Scribble, and Gray).| | Z-Image-Turbo-Fun-Controlnet-Union-2.1-lite-2602-8steps.safetensors | Same training scheme as the 2601 version, but with control applied to fewer layers. Supports multiple control conditions (Canny, Depth, Pose, MLSD, Hed, Scribble, and Gray). |

b. 2601 Models

| Name | Description | |--|--| | Z-Image-Turbo-Fun-Controlnet-Union-2.1-2601-8steps.safetensors | Compared to the old version, this model uses more diverse masks, a more reasonable training schedule, and multi-resolution control images (512–1536) instead of single resolution (512). This reduces artifacts and mask information leakage while improving robustness. Supports multiple control conditions (Canny, Depth, Pose, MLSD, Hed, and Scribble). | | Z-Image-Turbo-Fun-Controlnet-Tile-2.1-2601-8steps.safetensors | Compared to the old version, uses higher training resolution and a more refined distillation schedule,
