FAQPage Schema
How do I fine-tune a Vision-Language-Action model for custom robot tasks?

Fine-tuning a Vision-Language-Action model involves a two-stage training process: pre-training on diverse robot data and post-training to adapt to specific tasks. This Skill supports fine-tuning on a single GPU.

What is the OpenPI VLA model architecture for robot control?

The OpenPI VLA model architecture uses a PaliGemma backbone combined with a dedicated action decoder. This design enables general robot control and supports variants like pi0, pi0-FAST, and pi0.5.

Can I train a pi0 robot policy using just a single GPU?

Yes, you can train a pi0 robot policy on a single GPU. The PaliGemma backbone with a dedicated action decoder is specifically designed to enable fine-tuning on custom tasks without requiring multi-GPU hardware.

Does the pi0-FAST model support adaptation across multiple robot platforms?

Yes, the pi0-FAST model supports adaptation across multiple platforms. It is trained on diverse robot data during pre-training, allowing effective post-training adaptation for custom tasks across different environments.

What is the difference between pi0 and pi0.5 variants for VLA models?

The pi0, pi0-FAST, and pi0.5 variants are all foundation models trained on diverse robot data for general robot control. They utilize a two-stage training process to adapt to specific tasks across multiple platforms.
