This is based on the implementation of ACT found [here](https://github.com/tonyzhaozh/act). 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/v0.58.0/src/qai_hub_models/models/act) 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 | |---|---|---|---|---| | ONNX | float | Universal | QAIRT 2.45, ONNX Runtime 1.25.0 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/act/releases/v0.58.0/act-onnx-float.zip) | QNN_DLC | float | Universal | QAIRT 2.45 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/act/releases/v0.58.0/act-qnn_dlc-float.zip) | TFLITE | float | Universal | QAIRT 2.45 | [Download](https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/act/releases/v0.58.0/act-tflite-float.zip) For more device-specific assets and performance metrics, visit **[ACT on Qualcomm® AI Hub](https://aihub.qualcomm.com/models/act)**. ### Option 2: Export with Custom Configurations Use the [Qualcomm® AI Hub Models](https://github.com/qualcomm/ai-hub-models/blob/v0.58.0/src/qai_hub_models/models/act) 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 [ACT on GitHub](https://github.com/qualcomm/ai-hub-models/blob/v0.58.0/src/qai_hub_models/models/act) for usage instructions. ## Model Details **Model Type:** Model_use_case.robotics **Model Stats:** - Model checkpoint: act - Input resolution: 480x640 - Number of parameters: 83.92M - Model size (float): 255M ## Performance Summary | Model | Runtime | Precision | Chipset | Inference Time (ms) | Peak Memory Range (MB) | Primary Compute Unit |---|---|---|---|---|---|--- | ACT | ONNX | float | Snapdragon® X2 Elite | 6.716 ms | 4 - 4 MB | NPU | ACT | ONNX | float | Snapdragon® X Elite | 12.675 ms | 63 - 63 MB | NPU | ACT | ONNX | float | Snapdragon® 8 Gen 3 Mobile | 8.627 ms | 4 - 511 MB | NPU | ACT | ONNX | float | Snapdragon® 8 Gen 1 Mobile | 19.486 ms | 4 - 320 MB | NPU | ACT | ONNX | float | Qualcomm® Dragonwing™ QCS8550 (Proxy) | 12.151 ms | 0 - 79 MB | NPU | ACT | ONNX | float | Qualcomm® QCS8450 | 19.486 ms | 4 - 320 MB | NPU | ACT | ONNX | float | Qualcomm® Dragonwing™ IQ-9075 | 18.022 ms | 4 - 10 MB | NPU | ACT | ONNX | float | Snapdragon® 8 Elite Gen 5 Mobile | 5.984 ms | 1 - 444 MB | NPU | ACT | ONNX | float | Snapdragon® 8 Elite Mobile | 6.868 ms | 0 - 408 MB | NPU | ACT | ONNX | float | Qualcomm® Dragonwing™ Q-8750 | 6.868 ms | 0 - 408 MB | NPU | ACT | ONNX | float | Qualcomm® Dragonwing™ IQ-X7181 | 12.675 ms | 63 - 63 MB | NPU | ACT | QNN_DLC | float | Snapdragon® X2 Elite | 4.804 ms | 4 - 4 MB | NPU | ACT | QNN_DLC | float | Snapdragon® X Elite | 9.198 ms | 4 - 4 MB | NPU | ACT | QNN_DLC | float | Snapdragon® 8 Gen 3 Mobile | 6.074 ms | 0 - 336 MB | NPU | ACT | QNN_DLC | float | Snapdragon® 8 Gen 1 Mobile | 16.419 ms | 3 - 253 MB | NPU | ACT | QNN_DLC | float | Qualcomm® QCS8275 | 44.71 ms | 1 - 285 MB | NPU | ACT | QNN_DLC | float | Qualcomm® Dragonwing™ QCS8550 (Proxy) | 8.531 ms | 4 - 5 MB | NPU | ACT | QNN_DLC | float | Qualcomm® SA8775P | 13.792 ms | 1 - 269 MB | NPU | ACT | QNN_DLC | float | Qualcomm® SA8650P | 13.792 ms | 1 - 269 MB | NPU | ACT | QNN_DLC | float | Qualcomm® SA8255P | 13.792 ms | 1 - 269 MB | NPU | ACT | QNN_DLC | float | Qualcomm® QCS8450 | 16.419 ms | 3 - 253 MB | NPU | ACT | QNN_DLC | float | Qualcomm® Dragonwing™ IQ-9075 | 13.728 ms | 4 - 9 MB | NPU | ACT | QNN_DLC | float | Snapdragon® 8 Elite Gen 5 Mobile | 3.745 ms | 4 - 300 MB | NPU | ACT | QNN_DLC | float | Qualcomm® SA7255P | 44.71 ms | 1 - 285 MB | NPU | ACT | QNN_DLC | float | Snapdragon® 8 Elite Mobile | 4.717 ms | 4 - 273 MB | NPU | ACT | QNN_DLC | float | Qualcomm® SA8295P | 15.254 ms | 0 - 204 MB | NPU | ACT | QNN_DLC | float | Qualcomm® Dragonwing™ Q-8750 | 4.717 ms | 4 - 273 MB | NPU | ACT | QNN_DLC | float | Qualcomm® Dragonwing™ IQ-X7181 | 9.198 ms | 4 - 4 MB | NPU | ACT | TFLITE | float | Snapdragon® 8 Gen 3 Mobile | 6.105 ms | 0 - 409 MB | NPU | ACT | TFLITE | float | Snapdragon® 8 Gen 1 Mobile | 16.37 ms | 0 - 271 MB | NPU | ACT | TFLITE | float | Qualcomm® QCS8275 | 44.735 ms | 0 - 326 MB | NPU | ACT | TFLITE | float | Qualcomm® Dragonwing™ QCS8550 (Proxy) | 8.448 ms | 0 - 3 MB | NPU | ACT | TFLITE | float | Qualcomm® SA8775P | 13.83 ms | 0 - 279 MB | NPU | ACT | TFLITE | float | Qualcomm® SA8650P | 13.83 ms | 0 - 279 MB | NPU | ACT | TFLITE | float | Qualcomm® SA8255P | 13.83 ms | 0 - 279 MB | NPU | ACT | TFLITE | float | Qualcomm® QCS8450 | 16.37 ms | 0 - 271 MB | NPU | ACT | TFLITE | float | Qualcomm® Dragonwing™ IQ-9075 | 13.582 ms | 0 - 71 MB | NPU | ACT | TFLITE | float | Snapdragon® 8 Elite Gen 5 Mobile | 3.791 ms | 0 - 324 MB | NPU | ACT | TFLITE | float | Qualcomm® SA7255P | 44.735 ms | 0 - 326 MB | NPU | ACT | TFLITE | float | Snapdragon® 8 Elite Mobile | 4.733 ms | 0 - 283 MB | NPU | ACT | TFLITE | float | Qualcomm® SA8295P | 15.739 ms | 0 - 208 MB | NPU | ACT | TFLITE | float | Qualcomm® Dragonwing™ Q-8750 | 4.733 ms | 0 - 283 MB | NPU ## License * The license for the original implementation of ACT can be found [here](https://github.com/tonyzhaozh/act/blob/main/LICENSE). ## References * [Learning Fine-Grained Bimanual Manipulation with Low-Cost Hardware](https://arxiv.org/abs/2304.13705) * [Source Model Implementation](https://github.com/tonyzhaozh/act) ## Community * Join [our AI Hub Slack community](https://aihub.qualcomm.com/community/slack) to collaborate, post questions and learn more about on-device AI. * For questions or feedback please [reach out to us](mailto:ai-hub-support@qti.qualcomm.com).
