HaozheLiu-ST/T-GATE
A training-free method that accelerates diffusion models for text-to-image generation by decomposing and gating cross-attention mechanisms.

The project provides a technique to accelerate diffusion model inference through temporal attention decomposition. T-GATE (Temporally Gating Attention) identifies that cross-attention becomes redundant in later timesteps and proposes a gating approach to skip expensive computations without retraining. The method works across multiple diffusion frameworks including original DDPM, Diffusers, and ControlNet, offering speedups while maintaining image quality.
