OpenVLA provides an open-source vision-language-action model for robotic manipulation tasks.
About OpenVLA
OpenVLA is an open-source vision-language-action (VLA) model for robotic manipulation tasks, maintained as a public GitHub repository and built on Prismatic VLMs. It provides a codebase for training, fine-tuning, and deploying generalist robotic manipulation VLAs. The project supports arbitrary RLDS-format datasets including Open X-Embodiment data, scales model training from 1B to 34B parameters via PyTorch FSDP and Flash Attention, and offers multiple fine-tuning approaches including LoRA, partial, and full fine-tuning. It includes a lightweight inference interface compatible with HuggingFace transformers, a REST API serving script for integration with existing robot control stacks, and recent optimizations such as the OFT fine-tuning recipe and FAST action tokenizer for improved inference speed.
