# V-JEPA-2: Optimized for Qualcomm Devices
|
| 14 |
+
|
| 15 |
+
V-JEPA 2 (Video Joint-Embedding Predictive Architecture 2) is a self-supervised video encoder from Meta AI that uses a ViT (Vision Transformer) backbone to produce per-token video embeddings. It is used as a frozen backbone for downstream video understanding tasks such as action recognition and video retrieval.
|
| 16 |
+
|
| 17 |
+
This is based on the implementation of V-JEPA-2 found [here](https://github.com/facebookresearch/vjepa2).
|
| 18 |
+
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/v0.65.0/src/qai_hub_models/models/vjepa2) library to export with custom configurations. More details on model performance across various devices, can be found [here](#performance-summary).
|
| 19 |
+
|
| 20 |
+
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.
|
| 21 |
+
|
| 22 |
+
## Getting Started
|
| 23 |
+
There are two ways to deploy this model on your device:
|
| 24 |
+
|
| 25 |
+
### Option 1: Download Pre-Exported Models
|
| 26 |
+
|
| 27 |
+
Below are pre-exported model assets ready for deployment.
|
| 28 |
+
|
| 29 |
+
| Runtime | Precision | Chipset | SDK Versions | Download |
|
| 30 |
+
|---|---|---|---|---|
|
| 31 |
+
| ONNX | float | Universal | QAIRT 2.50, ONNX Runtime 1.30.0 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/vjepa2/releases/v0.65.0/vjepa2-onnx-float.zip)
|
| 32 |
+
| QNN_DLC | float | Universal | QAIRT 2.50 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/vjepa2/releases/v0.65.0/vjepa2-qnn_dlc-float.zip)
|

|
| 35 |
+
|
| 36 |
+
|
| 37 |
+
### Option 2: Export with Custom Configurations
|
| 38 |
+
|
| 39 |
+
Use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/v0.65.0/src/qai_hub_models/models/vjepa2) Python library to compile and export the model with your own:
|
| 40 |
+
- Custom weights (e.g., fine-tuned checkpoints)
|
| 41 |
+
- Custom input shapes
|
| 42 |
+
- Target device and runtime configurations
|
| 43 |
+
|
| 44 |
+
This option is ideal if you need to customize the model beyond the default configuration provided here.
|
| 45 |
+
|
| 46 |
+
See our repository for [V-JEPA-2 on GitHub](https://github.com/qualcomm/ai-hub-models/blob/v0.65.0/src/qai_hub_models/models/vjepa2) for usage instructions.
