AI BriefingT2I-Adapter Support and Efficiency Improvements for SDXL
Key point
T2I-Adapter, which is much lighter and faster than ControlNet while maintaining SDXL's control performance, has been introduced into diffusers.
Details
T2I-Adapter is an efficient plugin model that provides additional guidance while keeping the pretrained text-to-image model frozen. Unlike existing ControlNet, the model size is very small, and since it runs only once throughout the entire denoising process, the computational cost is much lower.
Key Features and Performance Comparison:
- Lightweight: For SDXL, it achieves a size of 79M, reducing the parameter count by 93.69% compared to ControlNet-SDXL (1251M).
- Efficiency: Storage capacity is also reduced by about 94%, providing significant advantages in terms of memory and speed.
- Support for diverse conditions: It supports various control signals such as sketch, canny, lineart, depth, and openpose.
T2I-Adapter support for SDXL has been officially added to Hugging Face's diffusers library, and developers can immediately utilize it through StableDiffusionXLAdapterPipeline.
