 ## Update for 2025-01-01
 
+- [Allegro Video](https://huggingface.co/rhymes-ai/Allegro)  
+  - optimizations: full offload and quantization support  
+  - *reference values*: width 1280 height 720 frames 88 steps 100 guidance 7.5  
+  - *note*: allegro model is really sensitive to input width/height/frames/steps  
+    and may result in completely corrupt output if those are not within expected range  
 - **Logging**:
   - reverted enable debug by default  
   - updated [debug wiki](https://github.com/vladmandic/automatic/wiki/debug)
