For local or self-hosted use, we recommend ComfyUI for node-based UI inference, or diffusers or GitHub for programmatic use.

QK Normalization: Implements the QK normalization technique to improve training Stability.
Adversarial Diffusion Distillation (ADD) (see the technical report), which allows sampling with 4 steps at high image quality.
Text Encoders：
- CLIPs: OpenCLIP-ViT/G, CLIP-ViT/L, context length 77 tokens
- T5: T5-xxl, context length 77/256 tokens at different stages of training
Training Data and Strategy:
This model was trained on a wide variety of data, including synthetic data and filtered publicly available data.
