    token := os.Getenv("LLM_API_KEY")
    log.Println("token:" + token)
    ctx := context.Background()
    llm, err := openai.New(
        openai.WithBaseURL("https://api.siliconflow.cn/v1"),
        openai.WithModel("deepseek-ai/DeepSeek-R1-0528-Qwen3-8B"),

    )
    if err != nil {
        log.Fatal(err)
    }
    prompt := "你是谁，版本是多少?"
    completion, err := llms.GenerateFromSinglePrompt(ctx, llm, prompt)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(completion)
