About
This model was produced by fine-tuning the OpenVLA 7B model via LoRA (r=32) on the LIBERO-Spatial dataset from the LIBERO simulation benchmark. We made a few modifications to the training dataset to improve final performance (see the OpenVLA paper for details).
Below are the hyperparameters we used for all LIBERO experiments:
use_lora == True, lora_rank == 32, lora_dropout == 0.0grad_accumulation_steps == 1)shuffle_buffer_size == 100_000See the OpenVLA GitHub README for instructions on how to run and evaluate this model in the LIBERO simulator.

Using it via the API
Once AxForge deploys openvla-finetuned-libero-spatial for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (openvla-finetuned-libero-spatial below is illustrative; you get the exact model name on deployment.)
