What it does
Molmo 2, a new suite of state-of-the-art vision-language models with open weights, training data, and training code, can analyze videos and multiple images at once.
We've released the full codebase behind Molmo 2 , making it possible for researchers and developers to go beyond the checkpoints and work with the complete stack—from data prep and training to evaluation and deployment. The repository includes scripts for pretraining, supervised fine-tuning (SFT), and long-context SFT, along with data downloading and preprocessing utilities, evaluation tooling, and support for inference with both transformers and vLLM. Whether you're looking to reproduce our training setup, fine-tune Molmo 2 on your own data for new tasks, or deploy in production, everything you need to get started is in the repository.
