Compare Stack AI vs. Windows AI Foundry

AI agents that interact and answer questions with users and complete tasks using your data and APIs. AI that can answer questions, summarize and extract insights from any long document. Transfer styles and formats, as well as tags and summaries between documents and data sources. Stack AI is used by developer teams to automate customer service, process documents, qualify leads, and search libraries of data. With a single button, you can try multiple LLM architectures and prompts. Collect data, run fine-tuning tasks and build the optimal LLM to fit your product. We host your workflows in APIs, so that your users have access to AI instantly. Compare the fine-tuning services of different LLM providers.

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.
