Sou desenvolvedor Java e sempre achei que integrar LLMs fosse coisa só do mundo Python. Este curso mostrou na prática como usar LangChain4j e Spring AI para montar um backend inteligente de verdade. Os exemplos com injeção de dependência do Spring deixaram tudo natural e fácil de aplicar no meu projeto.

Я джавист, и наконец увидел, как прикрутить LLM через LangChain4j без боли, примеры рабочие.
