NEW Running Python with Hosted Code Interpreter

Running Python with Hosted Code Interpreter

LLMs are great at generating code, but what if they could actually run it, too? With Spring AI and OpenAI's hosted Code Interpreter, your application can turn a prompt into executable Python, run it in the cloud, and even show you the code behind the answer.

NEW Switching to the OpenAI Responses API

Switching to the OpenAI Responses API

Upgrading to a more capable AI model should make your application smarter, not break its ability to use tools. With Spring AI 2.1, switching to OpenAI's Responses API takes just one configuration property. And it unlocks capabilities that go well beyond traditional chat completions.

NEW Speeding up RAG with Faster Embeddings

Speeding up RAG with Faster Embeddings

Is your RAG application stuck in the slow lane? The embedding model might be the bottleneck. In this recipe, we'll put five embedding options to the test and see how a simple Spring AI configuration change can dramatically speed things up.
