Spring AI

Spring AI is the application framework for AI engineering, connecting enterprise data and APIs with major AI models using familiar Spring conventions and a portable API.

Spring AI integrates generative AI into Java applications, leveraging the stability and scalability of the Spring Boot ecosystem. It provides a portable, vendor-neutral API for major AI model providers (e.g., OpenAI, Google, Amazon) and vector databases (like PostgreSQL/PGVector, PineCone): this abstraction ensures component swapping is simple. The framework streamlines complex AI engineering patterns, including Retrieval Augmented Generation (RAG), structured output mapping to POJOs, and Tool/Function Calling. Developers interact with models using the fluent `ChatClient` API, focusing on business logic instead of low-level API details, accelerating the development of enterprise-grade AI solutions.
