OpenVLA 7B (Prismatic-Compatible Version)

This is the same model as the OpenVLA 7B model, except that this checkpoint is in a format that is compatible with the training script from the original Prismatic VLMs project codebase, which the OpenVLA team built on top of to develop the OpenVLA model. See details for the OpenVLA 7B model here: https://huggingface.co/openvla/openvla-7b

This Prismatic-compatible checkpoint may be useful if you wish to fully fine-tune OpenVLA (all 7.5 billion parameters) via native PyTorch Fully Sharded Data Parallel (FSDP) using the Prismatic VLMs training script. If you instead wish to do Parameter-Efficient Fine-Tuning via LoRA, you can use the OpenVLA checkpoint linked above, which is compatible with the Hugging Face transformers library. We recommend fine-tuning via LoRA if you do not have sufficient compute to fully fine-tune a 7B-parameter model (e.g., multiple A100/H100 GPUs).

Usage Instructions

See the OpenVLA GitHub README for instructions on how to use this checkpoint for full fine-tuning.
