Stability AI Releases Stable Diffusion 3.5 Large ControlNet Models

Stability AI has today released three new ControlNet models specifically designed for Stable Diffusion 3.5 Large. These models include Blur, Canny, and Depth, providing creators and developers with more precise control over image generation.

Features of the New ControlNet Models

Blur ControlNet

Depth ControlNet

  • Supports ultra-high resolution image upscaling up to 8K and 16K resolutions
  • Particularly suitable for converting low-resolution images into large, detail-rich visual works
  • Recommended for image tiling between 128 and 512 pixels

Canny ControlNet

Depth ControlNet

  • Uses Canny edge maps to control the structure of generated images
  • Especially suitable for illustration creation, but also works well with various artistic styles
  • Enables precise control over image outlines and structure

Depth ControlNet

Depth ControlNet

  • Uses depth maps generated by DepthFM to guide image generation
  • Excellent for architectural rendering and 3D asset texturing
  • Particularly useful for scenarios requiring precise control over image composition

Stable Diffusion 3.5 Large ControlNet Licensing

These models are released under the Stability AI Community License, with key features including:

  • Free for non-commercial use, including scientific research
  • Free for commercial use for organizations with annual revenue under $1 million
  • Users retain ownership of generated content

Technical Recommendations

When using these ControlNet models, it is recommended to:

  • Start with a ControlNet strength of 0.7-0.8
  • Use the Euler sampler with increased steps (50-60) for better results
  • Higher step counts are particularly beneficial when using the Canny model

Safety Commitment

Stability AI states their commitment to safe and responsible AI practices, with measures in place to prevent model misuse. More safety-related information can be found on their safety page.
