xvla_sharpie_holder_v1

by Parsh Gandhi ParshG/xvla_sharpie_holder_v1

xvla_sharpie_holder_v1 is an open-weight model for robotics from Parsh Gandhi, released under Apache License 2.0. It has 880M parameters. At 16-bit it needs about 2.1 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index.

How to Get Started with the Model

New to LeRobot? These guides cover the full workflow:

The short version to run and train this policy:

Run the policy on your robot

lerobot-rollout \
  --strategy.type=base \
  --robot.type=so_follower \
  --robot.port=<your_robot_port> \
  --robot.cameras="{ <camera_1>: {type: opencv, index_or_path: <index_or_path>, width: 640, height: 480, fps: 30}, <camera_2>: {type: opencv, index_or_path: <index_or_path>, width: 640, height: 480, fps: 30}}" \
  --policy.path=ParshG/xvla_sharpie_holder_v1 \
  --task="Put the Sharpie in the pen holder" \
  --duration=60

Replace the remaining <...> placeholders with your own values: --robot.port and the camera names/indices are specific to your machine, and the camera names must match the observation keys this policy was trained on.

When --strategy.type=base is used the script doesn't record the episodes. Skipping duration will make the policy run indefinitely. For more information look at rollout documentation.

Train your own policy

Fine-tune your own from the same base model, lerobot/xvla-base:

lerobot-train \
  --dataset.repo_id=${HF_USER}/<dataset> \
  --policy.path=lerobot/xvla-base \
  --output_dir=outputs/train/<policy_repo_id> \
  --job_name=lerobot_training \
  --policy.device=cuda \
  --policy.repo_id=${HF_USER}/<policy_repo_id> \
  --wandb.enable=true

Writes checkpoints to outputs/train/<policy_repo_id>/checkpoints/.

Questions About xvla_sharpie_holder_v1

How much GPU memory does xvla_sharpie_holder_v1 need?

About 2.1 GB at 16-bit and 0.5 GB at 4-bit: the weights (880M parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run xvla_sharpie_holder_v1 on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

Can I use xvla_sharpie_holder_v1 commercially?

Yes. xvla_sharpie_holder_v1 is released under Apache License 2.0. The Apache License 2.0 is a permissive open-source license. It permits commercial use, modification and redistribution.

Paper: Zheng et al., 2025, “X-VLA: Soft-Prompted Transformer as Scalable Cross-Embodiment Vision-Language-Action Model” (arXiv:2510.10274) Successful generalist Vision-Language-Action (VLA) models rely on effective training across diverse robotic platforms with large-scale, cross-embodiment, heterogeneous datasets. To facilitate and leverage the heterogeneity in rich robotic data sources, X-VLA introduces a Soft Prompt approach with minimally added parameters: we infuse prompt-learning concepts into cross-embodiment robot learning, introducing separate sets of learnable embeddings for each distinct embodiment.

A vectorv1.1 network, Robotensor's two-arm Behavior Prompting Policy, submitted to Attune's Vector competition (Bittensor netuid 58). Its image encoders start from the Behavior Prompting Policy authors' own LIBERO policy (austinpatel/libero, MIT; Patel, Pekarek, Castro Hernandez and Song, 2026); the rest was trained on RoboTwin expert demonstrations of two Franka arms.
