Abstract: We introduce Pixtral-12B, a 12--billion-parameter multimodal language model.
Pixtral-12B is trained to understand both natural images and documents,
achieving leading performance on various multimodal benchmarks, surpassing a
number of larger models. Unlike many open-source models, Pixtral is also a
cutting-edge text model for its size, and does not compromise on natural
language performance to excel in multimodal tasks. Pixtral uses a new vision
encoder trained from scratch, which allows it to ingest images at their natural
resolution and aspect ratio. This gives users flexibility on the number of
tokens used to process an image. Pixtral is also able to process any number of
images in its long context window of 128K tokens. Pixtral 12B substanially
outperforms other open models of similar sizes (Llama-3.2 11B \& Qwen-2-VL 7B).
It also outperforms much larger open models like Llama-3.2 90B while being 7x
smaller. We further contribute an open-source benchmark, MM-MT-Bench, for
evaluating vision-language models in practical scenarios, and provide detailed
analysis and code for standardized evaluation protocols for multimodal LLMs.
