Understanding Attention Algorithms and Their Backends for Image and Video Generation
- 20 July 2026
ComfyUI has become a widely adopted tool for running modern generative AI workloads, from text-to-image and video generation to more advanced pipelines like WAN2.2. Its node-based workflow makes it accessible without requiring deep coding knowledge, but under the hood it still relies heavily on one of the most important building blocks in modern AI models: attention.
