- R · What Makes It Special
- Meta's CM3Leon, a retrieval-augmented, token-based, decoder-only multimodal model that generates and infills both text and images, trained with a recipe adapted from text-only LLMs (retrieval-augmented pretraining, then multi-task supervised fine-tuning); Meta reports state-of-the-art text-to-image results (zero-shot MS-COCO FID of 4.88) with 5x less training compute than comparable methods, plus language-guided image editing.
