Generates images from text descriptions using a multi-stage cascading diffusion architecture where a base UNet first generates low-resolution (64x64) images from noise conditioned on T5 text embeddings, then successive super-resolution UNets (SRUnet256, SRUnet1024) progressively upscale and refine details. Each stage conditions on both text embeddings and outputs from previous stages, enabling efficient high-quality synthesis without requiring a single massive model.
Unique: Implements Google's cascading DDPM architecture with modular UNet variants (BaseUnet64, SRUnet256, SRUnet1024) that can be independently trained and composed, enabling fine-grained control over which resolution stages to use and memory-efficient inference through selective stage execution
vs alternatives: Achieves better text-image alignment than single-stage models and lower memory overhead than monolithic architectures by decomposing generation into specialized resolution-specific stages that can be trained and deployed independently
Implements classifier-free guidance mechanism that allows steering image generation toward text descriptions without requiring a separate classifier, using unconditional predictions as a baseline. Incorporates dynamic thresholding that adaptively clips predicted noise based on percentiles rather than fixed values, preventing saturation artifacts and improving sample quality across diverse prompts without manual hyperparameter tuning per prompt.
Unique: Combines classifier-free guidance with dynamic thresholding (percentile-based clipping) rather than fixed-value thresholding, enabling automatic adaptation to different prompt difficulties and model scales without per-prompt manual tuning
