OpenVLA-OFT Fine-tuning and evaluation workflows for OpenVLA-OFT and OpenVLA-OFT+ from the official codebase. Covers blank-machine setup plus LoRA-based adaptation of OpenVLA for robot action generation with continuous action prediction heads. Quick start Clone the public repo, follow the official setup, then evaluate a pretrained LIBERO checkpoint: Core concepts What OpenVLA-OFT changes : Standard OpenVLA tokenizes continuous actions into discrete bins, losing precision. OFT replaces this with dedicated continuous action heads (L1 regression or diffusion) while keeping the VLA backbone froze…
