## Summary

Hugging Face trains a 20B open-weight model with a LoRA adapter to generate slide decks in a company's design language, splitting work between a designer role that writes a JSON brief and a coder role that writes pptxgenjs code per slide. The team says the model ranks first on two of three domains on PresentBench, and that per-slide coding runs about 6–7 times faster through parallel calls.
