Details for 2025-12-26

• Models
  • LongCat Image in Image and Image Edit variants
    LongCat is a new 8B diffusion base model using Qwen-2.5 as text encoder
  • Qwen-Image-Edit 2511 in base and pre-quantized variants
    Key enhancements: mitigate image drift, improved character consistency, enhanced industrial design generation, and strengthened geometric reasoning ability
  • Qwen-Image-Layered in base and pre-quantized variants
    Qwen-Image-Layered, a model capable of decomposing an image into multiple RGBA layers
    note: set number of desired output layers in settings -> model options
  • Ovis Image 7B
    Ovis Image is a new text-to-image base model based on Qwen3 text-encoder and optimized for text-rendering
• Features
  • Google Gemini and Veo models support for both Dev and Vertex access methods
    see docs for details
  • Z-Image Turbo support loading transformer file-tunes in safetensors format
    as with any transformers/unet finetunes, place them then models/unet
    and use UNET Model to load safetensors file as they are not complete models
  • Z-Image Turbo support for ControlNet Union
    includes 1.0, 2.0 and 2.1 variants
  • Detailer support for segmentation models
    some detection models can produce exact segmentation mask and not just box
    to enable, set use segmentation option
    added segmentation models: anzhc-eyes-seg, anzhc-face-1024-seg-8n, anzhc-head-seg-8n
