TL;DR
Spring AI is an official Spring project that integrates AI models into Java using familiar patterns: auto-configuration, dependency injection, and vendor-portable abstractions.
It reached 1.0 GA in May 2025 and shipped 1.1 in November 2025 with 850+ improvements, including full MCP (Model Context Protocol) integration.
Supports 20+ AI model providers (OpenAI, Anthropic, Google, Ollama, and more) and 12+ vector stores behind a single consistent API.
If your team runs Spring Boot, you have no good reason to write raw HTTP calls to an LLM anymore.
