Palette: teaching a small model to build decks in your design language

Palette is a system that uses a small, fine-tuned model to generate slide decks adhering to a specific design language. The approach splits the task into two roles: a "designer" plans the deck's structure and content, while a "coder" generates the JavaScript code for each individual slide. This model was trained on synthetic data that includes the reasoning behind design choices, created using a larger teacher model and a check-and-repair feedback loop. The system allows users to guide the generation process with plain English directives to control specific design elements like layout or tone. This method enables a small, self-hosted model to compete with larger frontier models for creating on-brand, confidential presentations.
