# Quick AI Application Builder (QAI AppBuilder)
QAI AppBuilder extends the capabilities of the Qualcomm® AI Runtime SDK by facilitating the efficient deployment of AI models. QAI AppBuilder is engineered to assist developers in leveraging the Qualcomm® AI Runtime SDK for seamless model execution on Windows on Snapdragon X and X2 (WoS) platform.
It abstracts the model execution APIs into streamlined interfaces for loading models onto the NPU/HTP and performing inference, significantly reducing the complexity of deployment for developers.
For more information, see [QAI AppBuilder](https://github.com/quic/ai-engine-direct-helper/tree/main?tab=readme-ov-file).
## QAI AppBuilder Features
- Simple: Ready to use, no AI experience needed.
- Supports Python, C++, and tools like LangFlow.
- Runs locally on NPU with low latency.
- All data stays on-device, no cloud cost, and fully local.
- Works with OpenAI-style APIs for easy integration.
## More Feature Details
- - **QAI AppBuilder Launcher**: Qualcomm offers a comprehensive set of sample applications to help developers quickly explore the QAI AppBuilder capabilities.
- For some key examples, it also provides setup scripts that streamline environment configuration, enabling users to experience core functionalities in less time. These scripts can be accessed via the [QAI AppBuilder Launcher](https://github.com/quic/ai-engine-direct-helper/blob/main/tools/launcher).
- **Tutorial**: Example tutorial on how to run an AI model using QAI AppBuilder can be found at [Tutorial](https://github.com/quic/ai-engine-direct-helper/blob/main/docs/tutorial.ipynb).
- **Sample Use Cases**: Qualcomm provides many Python sample use cases <https://github.com/quic/ai-engine-direct-helper/tree/main/samples/python> and C++ Samples <https://github.com/quic/ai-engine-direct-helper/tree/main/samples/c++> C++ sample use cases which can be run directly. The models used in these samples are from AI-Hub. Qualcomm also provides several [WebUI AI applications](https://github.com/quic/ai-engine-direct-helper/blob/main/samples/webui/README.md) based on QAI AppBuilder that you can quickly try.
1. **Tools**: Langflow is a third-party development tool designed to simplify the creation and deployment of AI models. The QAI Builder Langflow package showcases how to run Langflow on Windows on Snapdragon X and X2 (WoS) platform, utilizing the NPU to accelerate AI model inference. For more information, see [QAI Builder Langflow](https://github.com/quic/ai-engine-direct-helper/tree/main/tools/langflow).
2. **OpenAI support**: QAI AppBuilder includes a feature that provides an OpenAI-compatible API service in both C++ and Python implementations. For more information, see [Python based service](https://github.com/quic/ai-engine-direct-helper/blob/main/samples/genie/python/README.md) and [C++ based service](https://github.com/quic/ai-engine-direct-helper/blob/main/samples/genie/c++/README.md).
