NEW Decomposing Answers into Claims for Fact-Checking

Decomposing Answers into Claims for Fact-Checking

An AI-generated answer can contain several factual claims. It only takes one unsupported claim to make the answer misleading. Instead of fact-checking the answer as a whole, what if we broke it into individual claims and checked each one separately?

NEW Fact-Checking AI Responses

Fact-Checking AI Responses

Even when an LLM has all the facts it needs, it can still get them wrong. My latest Spring AI Recipe explores FactCheckingEvaluator, including a surprising limitation that shows why fact-checking AI responses isn't always as straightforward as it seems.

NEW Securing an MCP Server with OAuth

Securing an MCP Server with OAuth

Securing an MCP server with an API key is easy, but sometimes you need something more robust. In this recipe, we’ll put OAuth 2.0 to work with Spring AI to secure an MCP server. And we’ll even apply fine-grained authorization to individual tools.
