Great question — answering as the UphillTech team:
You should use langchain4j-ollama-spring-boot-starter or register your OllamaChatModel using Spring Boot @Bean annotation. So that the @AiService annotation could found the bean and auto-inject it. BTW, you should not implement the @AiService interface on your own, langchain4j will implement it using Proxy automatically. Please refer to docs .
