VLA-Adapter SO-101 Push Cube — Step 10,000

This repository contains an intermediate 10,000-optimizer-step checkpoint of VLA-Adapter fine-tuned for the SO-101 push_cube task.

Training configuration

The RLDS dataset contains 50 trajectories and 13,679 transitions. Actions and proprioceptive states follow the six-motor SO-101 representation.

Checkpoint contents

• model.safetensors: VLA model with the LoRA weights merged
• lora_adapter/: trainable LoRA adapter
• action_head--10000_checkpoint.pt: continuous action head
• proprio_projector--10000_checkpoint.pt: proprioception projector
• vla_extras--10000_checkpoint.pt: trainable VLA extras such as action queries
• training_state--10000_checkpoint.pt: optimizer, scheduler, scaler, and RNG state
• processor, tokenizer, configuration, and dataset statistics

The separate action head and proprio projector are required for the SO-101 continuous-control policy. The merged model.safetensors alone is not the complete policy.

This is an intermediate training checkpoint, not the final 20,000-step model. Review the base model, dataset, and code licenses before redistribution or deployment. Validate the policy in simulation or a controlled robot workspace before operating physical hardware.
