Windows AI Foundry serves as a cohesive, trustworthy, and secure environment that facilitates every stage of the AI developer journey, encompassing model selection, fine-tuning, optimization, and deployment across various processors, including CPU, GPU, NPU, and cloud solutions. By incorporating tools like Windows ML, it empowers developers to seamlessly integrate their own models and deploy them across a diverse ecosystem of silicon partners such as AMD, Intel, NVIDIA, and Qualcomm, which collectively cater to CPU, GPU, and NPU needs. Additionally, Foundry Local enables developers to incorporate their preferred open-source models, enhancing the intelligence of their applications. The platform features ready-to-use AI APIs that leverage on-device models, meticulously optimized for superior efficiency and performance on Copilot+ PC devices, all with minimal setup required. These APIs encompass a wide range of functionalities, including text recognition (OCR), image super resolution, image segmentation, image description, and object erasing. Furthermore, developers can personalize the built-in Windows models by utilizing their own data through LoRA for Phi Silica, thereby increasing the adaptability of their applications. Ultimately, this comprehensive suite of tools makes it easier for developers to innovate and create advanced AI-driven solutions.
