子业务空间的模型调用

Python（SDK）

    {'role': 'user', 'content': '你是谁？'}
]
response = dashscope.Generation.call(
    # 若没有配置环境变量，请用百炼API Key将下行替换为：api_key="sk-xxx"
    api_key=os.getenv('DASHSCOPE_API_KEY'),
    model="qwen-plus", # 此处以qwen-plus为例，可按需更换模型名称。模型列表：https://help.aliyun.com/model-studio/getting-started/models
    messages=messages,
    result_format='message'
    )
