TL;DR Spring AI is the Spring ecosystem’s unified abstraction layer for generative AI services (LLMs, embeddings, vector stores, chat‑agents, etc.). In 2026 it matters because: It hides vendor‑specific APIs (OpenAI, Anthropic, Azure, AWS Bedrock, etc.) behind a single, type‑safe Spring interface. It integrates natively with Spring Boot, Spring Cloud, and the new spring-boot-starter-ai starter, enabling rapid prototyping and production‑grade observability. It supports the emerging AI‑first architecture patterns: RAG pipelines, tool‑calling agents, and multimodal workflows. The tutorial walks you through building a complete end‑to‑end Spring Boot application that: Configures an LLM (e.g., OpenAI GPT‑4o) via Spring properties.…
