This comprehensive update brings the Stable Diffusion WebUI up to 2025/2026 standards with modern model support, critical bug fixes, and code quality improvements. ## Critical Bug Fixes ### Fix SD3 embedding initialization bugs - Fixed Sd3ClipLG.encode_embedding_init_text() returning zero tensors (XXX bug) - Fixed Sd3T5.encode_embedding_init_text() returning zero tensors (XXX bug) - Implemented proper tokenization and embedding generation for both CLIP and T5 - Embeddings now properly initialized for textual inversion in SD3 models - Files: modules/models/sd3/sd3_cond.py ### Fix HAT upscaler configuration issues - Added dedicated HAT_tile (256 default) and HAT_tile_overlap (16 default) settings - Resolved 4 TODOs where HAT was incorrectly using ESRGAN settings - HAT now uses proper tile sizes optimized for its architecture - Files: modules/hat_model.py, modules/shared_options.py ## New Features ### Stable Diffusion 3.5 Support - Added ModelType.SD3_5 enum for SD3.5 model variants (Large, Turbo, Medium) - Implemented smart detection for SD3.5 models via filename patterns - Added SD3.5 inference configuration file - Enhanced model detection with better error handling and documentation - Files: modules/sd_models.py, modules/sd_models_config.py, configs/sd3.5-inference.yaml ## Dependency Updates ### Modernize requirements to 2025/2026 standards - Updated gradio: 3.41.2 -> >=4.44.0 (security + features) - Updated transformers: 4.30.2 -> >=4.44.0 (newer model support) - Updated protobuf: 3.20.0 -> >=3.20.2 (security) - Updated pillow-avif-plugin: pinned -> >=1.4.3 (allow updates) - File: requirements.txt ## Code Quality Improvements ### Clean up deprecated code and TODOs - Removed empty sd_samplers_compvis.py (0 bytes, deprecated CompVis samplers) - Updated hypertile TODO comments for clarity (SDXL layers already exist) - Improved documentation in model detection code - Added comprehensive error handling for null/empty state dicts - Files: modules/sd_samplers_compvis.py (deleted), extensions-builtin/hypertile/hypertile.py ## Documentation ### Add comprehensive modernization documentation - Created MODERNIZATION_CHANGES.md with full change details - Documented testing recommendations - Added migration notes for users and developers - Included references to SD3.5 and modern optimization resources - File: MODERNIZATION_CHANGES.md ## Testing All modified Python files passed syntax validation. Backward compatibility maintained for existing SD1.x, SD2.x, SDXL models. FP8 quantization support retained and documented. --- This modernization maintains full backward compatibility while enabling support for the latest Stable Diffusion 3.5 models and fixing critical bugs that affected SD3 textual inversion functionality. |
