Wall-X is the open-source training and inference stack for X Square Robot's WALL series of embodied foundation models (VLAs) for general-purpose robot manipulation. It includes LeRobot data preparation, model configuration, flow-matching and FAST action branches, serving/evaluation utilities, and CUDA operators compiled at install time.

Use cases

• train a vision-language-action model for robot manipulation
• fine-tune an embodied foundation model on custom robot demonstration data
• run inference on a real robot arm from a pretrained VLA checkpoint
• prepare LeRobot-format datasets for embodied model training
• evaluate robot manipulation policies in closed-loop rollouts
• adapt a pretrained VLA to new manipulation tasks

When to choose

• you need an open-source VLA training/inference stack for real-robot manipulation
• you want to fine-tune or deploy WALL-OSS models on your own robot hardware
• you work with LeRobot datasets and want a flow-matching or FAST action head

When to avoid

• you need a lightweight simulation-only robotics toolkit without GPU-heavy training
• your platform is not Linux with CUDA 12.x GPUs
• you want a plug-and-play robot controller with no model training involved
