I also encountered this problem, but I solved it.
It's caused by apiKey, if you don't need apiKey, set EMPTY

OpenAiApi api = OpenAiApi.builder() .apiKey("EMPTY") .baseUrl("http://192.168.0.0.1:8001/") .build();

I set the key, it shouldn't be related to this

I found out in the VLMM project whether it is related to httpClientBuilder
The VLMM project uses HttpClient.Version.HTTP_1_1 ，Spingai uses HTTP2 ，Can you verify if there is a relationship

We adopted other people's suggestions to achieve this. Suggest adding an independent parameter to set the default request specification

@configuration
public class HttpClientConfiguration {
private HttpClient client() {
return HttpClient.newBuilder()
.version(HttpClient.Version.HTTP_1_1)
.build();
}

@Bean
@Primary
public RestClient.Builder restClientBuilder() {
    return RestClient.builder()
            .requestFactory(new JdkClientHttpRequestFactory(client()));
}

@Bean
@Primary
public WebClient.Builder webClientBuilder() {
    return WebClient.builder()
            .clientConnector(new JdkClientHttpConnector(client()));
}

}
