Fastn AI is a web-based, composable AI middleware platform that lets enterprises integrate, configure, and deploy AI services without deep engineering work. It provides prebuilt components, called �Fastn blocks�, to chain together large language models, APIs, databases, and user inputs into usable, secure applications. Fastn focuses on orchestration: it doesn�t build models but makes it easy to operationalize them. You can build flows using drag-and-drop logic, set permissions, control latency, and monitor pipelines, all with audit trails and compliance in mind. The platform supports popular LLMs and tools like OpenAI, Claude, LangChain, Pinecone, and more, making it ideal for real-world AI use cases at scale.
