# Pi0.5: Optimized for Qualcomm Devices
Pi0.5 is a vision-language-action model that co-trains on diverse data sources (robot demos, web data, semantic subtasks) to enable open-world generalization for long-horizon robotic manipulation.
This is based on the implementation of Pi0.5 found [here](https://github.com/Physical-Intelligence/openpi).
This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/main/src/qai_hub_models/models/pi05) library to export with custom configurations. More details on model performance across various devices, can be found [here](#performance-summary).
Qualcomm AI Hub Models uses [Qualcomm AI Hub Workbench](https://workbench.aihub.qualcomm.com) to compile, profile, and evaluate this model. [Sign up](https://myaccount.qualcomm.com/signup) to run these models on a hosted Qualcomm® device.
## Getting Started
There are two ways to deploy this model on your device:
### Option 1: Download Pre-Exported Models
Below are pre-exported model assets ready for deployment.
| Runtime | Precision | Chipset | SDK Versions | Download |
|---|---|---|---|---|
| QNN_CONTEXT_BINARY | mixed | Qualcomm® QCS9075 | QAIRT 2.45 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/pi05/releases/v0.54.0/pi05-qnn_context_binary-mixed-qualcomm_qcs9075.zip)
For more device-specific assets and performance metrics, visit **[Pi0.5 on Qualcomm® AI Hub](https://aihub.qualcomm.com/models/pi05)**.
### Option 2: Export with Custom Configurations
Use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/main/src/qai_hub_models/models/pi05) Python library to compile and export the model with your own:
- Custom weights (e.g., fine-tuned checkpoints)
- Custom input shapes
- Target device and runtime configurations
This option is ideal if you need to customize the model beyond the default configuration provided here.
See our repository for [Pi0.5 on GitHub](https://github.com/qualcomm/ai-hub-models/blob/main/src/qai_hub_models/models/pi05) for usage instructions.
