CM3leon is a multimodal foundation model from Meta AI, introduced in July 2023 on ai.meta.com. Pronounced like "chameleon," it combines text-to-image and image-to-text generation in one architecture instead of separate specialized models.

Meta trained CM3leon with a recipe adapted from text-only language models: large-scale retrieval-augmented pre-training followed by multitask supervised fine-tuning. The causal masked mixed-modal (CM3) design lets the model generate sequences of text and images conditioned on mixed image and text inputs, expanding beyond earlier models that handled only one direction.

On the MS-COCO text-to-image benchmark, CM3leon reported a zero-shot FID score of 4.88 while using five times less compute than prior transformer-based text-to-image methods. Meta positions it for researchers and teams working on unified vision-language generation, editing, captioning, and visual question answering.
