In this lesson

call a model through Spring AI.

Planned topics

Spring AI is a Spring project that gives one API for several model providers.
ChatClient has a fluent API: prompt(), system(...), user(...), call().
A prompt template fills placeholders, so prompts are not built by string concatenation.
Advisors wrap calls to add behavior such as logging or memory; here we only name the idea.
The provider and model come from configuration and the starter you add, not from your code.

Demonstration

java

String text = chatClient.prompt()
    .system("You write short product descriptions.")
    .user(u -> u.text("Describe: {name}, {features}").param("name", name).param("features", features))
    .call()
    .content();
