Spring AI ChatClient basics
Free Spring AI module: ChatClient, prompt templates, and model configuration for Java backends. First topics open in the browser — no sign-up.
Free Spring AI module on ChatClient, prompts, and model configuration. First topics open in the browser with no account.
Spring AI is how Java teams wrap chat models without a Python service. This guest module covers ChatClient, prompt templates, and the configuration you need before you wire RAG. It is the same foundations track paid users study.
It is not a debug lab. If you want production incidents, use HikariCP, RestTemplate, Kafka, or Actuator. Use this module when the job post lists Spring AI or Gen AI backends.
What you will cover
- ChatClient vs raw HTTP to the model
- Prompt templates and system messages
- Model and API-key configuration
- Where RAG fits after foundations
- First topics free; remaining after sign-in

Common questions
Is there a free Spring AI tutorial?
Yes. Spring AI Foundations opens the first ChatClient and prompt topics without an account. Sign in for the rest of the Spring AI track.
Do I need an OpenAI key to start?
You can read the foundations pages without a key. Calling a live model later needs your own provider credentials; this preview does not bill you.
Is this the same as a production debug lab?
No. Debug labs are broken Spring code you diagnose. This module is the Spring AI API. Both are free to start from the Try Debug hub.
