## What it is
Spring AI is an application framework for AI engineering that provides Spring-friendly, portable abstractions for integrating AI models into Java applications. It offers unified APIs for chat completion, embeddings, text-to-image, vector stores, function calling, and structured output mapping across all major AI providers.

## Use cases
- build a chatbot in Java with Spring Boot
- switch between OpenAI, Anthropic, and Ollama with minimal code changes
- map LLM responses to Java POJOs with structured outputs
- implement RAG with vector databases like PGVector, Milvus, or Pinecone
- add function calling so a model can invoke Java methods
- build an ETL pipeline for document ingestion and embedding
- add observability to AI operations in enterprise apps

## When to choose
- you are building AI features in a Java/Spring Boot application
- you want portable abstractions to avoid vendor lock-in across AI model providers
- you need typed, POJO-based APIs instead of raw HTTP calls to AI services
- you want Spring ecosystem integration for dependency injection, configuration, and observability

## When to avoid
- you are a Python developer who prefers LangChain or LlamaIndex
- you need a lightweight, framework-free client for a single AI provider
- your project does not use the JVM or Spring ecosystem
- you need cutting-edge agent features that only exist in Python AI tooling first
