400 error `you must provide a model parameter.`

[yuluo-yx]

When I use the builder method of ChatModel to build the model, I get a 400 error because I don't know the model parameters.

Is this how it's supposed to be designed?

I see openai docs: https://docs.spring.io/spring-ai/reference/api/chat/openai-chat.html#_custom_api_key_configuration

@GetMapping("/call/openai")
public String call() {

    OpenAiChatModel chatModel = OpenAiChatModel.builder()
            .openAiApi(OpenAiApi.builder()
                    .apiKey("sk-xxxxx")
                    .baseUrl("https://dashscope.aliyuncs.com/compatible-mode/v1/chat/completions")
                    .build()
            ).defaultOptions(OpenAiChatOptions.builder()
                    .temperature(0.7)
                    .maxTokens(1000)
                    .build()
            ).build();

    return chatModel.call("hi");
}

log:

org.springframework.ai.retry.NonTransientAiException: 400 - {"error":{"message":"you must provide a model parameter. ","type":"invalid_request_error","param":null,"code":null},"request_id":"c39eba3c-2766-473c-a4c2-46c73d3470ee"}

maybe the options parameter should have a default value?
