@799452017 There are parts of all the images where the IP addresses are not fully obscured. (Just letting you know, just in case.)

Check the original HTTP request body using the requestInterceptor. And please share the result if you need more help.

Comment From: apappascs

here it looks like that you are using DeepSeek-R1 . So may better use the deepseek starter.

<dependency>
    <groupId>org.springframework.ai</groupId>
    <artifactId>spring-ai-starter-model-deepseek</artifactId>
</dependency>

also the dependencies needs to be updated from <spring-ai.version>1.0.0-M6</spring-ai.version> to <version>1.0.0-SNAPSHOT</version>

you are also mentioning openai4j which is not related to spring-ai in any way.

I will recomend you to follow the documentation : https://docs.spring.io/spring-ai/reference/getting-started.html https://docs.spring.io/spring-ai/reference/api/chat/deepseek-chat.html
