    Alibaba Cloud Model Studio:Create a response

    Last Updated:Jul 14, 2026

    Use the OpenAI-compatible Responses API to call the Qwen model. This topic describes the input and output parameters and provides a call example.

    Advantages over the OpenAI Chat Completions API:

    • Built-in tools: Get better results on complex tasks with built-in tools like web search, web scraping, a code interpreter, text-to-image, image-to-image, and knowledge base search. For more information, see tool calling.

    • More flexible input: Supports both direct string input and message arrays in the chat format.

    • Simplified context management: Avoid manually constructing a message history array by passing the previous_response_id from the last response.

    • Convenient context caching: Add x-dashscope-session-cache: enable (default value: disable) to the request header to enable automatic server-side caching of the conversation context. This reduces inference latency and costs for multi-turn conversations with no code changes required. For details, see session cache.

    Compatibility and limitations

    This API is compatible with OpenAI to reduce developer migration cost, but differs in its parameters, functionality, and behavior.

    Core Principle: Only the parameters explicitly listed in this document are processed. Any OpenAI parameters not mentioned are ignored.

    The following key differences will help you adapt quickly:

    • Unsupported Parameters: This API does not support some OpenAI API parameters, such as the asynchronous execution parameter background. The API currently supports only synchronous calls.

    • Reasoning Effort Control: Use the reasoning.effort parameter to control the model's reasoning effort. For usage details, see the description of this parameter.

    Replace {WorkspaceId} with your actual workspace ID.

    Important

    Alibaba Cloud Model Studio has released workspace-specific domains for the China (Beijing), Singapore, and China (Hong Kong) regions. The new dedicated domains deliver superior performance and higher stability for inference requests. We recommend migrating to the new domains:

    • China (Beijing): from https://dashscope.aliyuncs.com to https://{WorkspaceId}.cn-beijing.maas.aliyuncs.com

    • Singapore: from https://dashscope-intl.aliyuncs.com to https://{WorkspaceId}.ap-southeast-1.maas.aliyuncs.com

    • China (Hong Kong): from https://cn-hongkong.dashscope.aliyuncs.com to https://{WorkspaceId}.cn-hongkong.maas.aliyuncs.com

    {WorkspaceId} is your workspace ID, which can be found on the Workspace Details page in the Alibaba Cloud Model Studio console. The existing domain remains fully functional.

    Important

    The legacy URL path /api/v2/apps/protocols/compatible-mode/v1/responses for the OpenAI-compatible Responses API will be deprecated soon. Please migrate to the new path /compatible-mode/v1/responses as soon as possible.

    • none: Prevents the model from calling any tool.

    • required: Forces the model to call a tool. This is only available when the tools list contains exactly one tool.

    Object mode

    Restricts the model to a specific set of tools for selection and calling.

    Properties

    mode string (required)

    • auto: The model automatically decides whether to call a tool from the provided list.

    • required: Forces the model to call a tool from the provided list. This is only available when the tools list contains exactly one tool.

    tools array(required)

    A list of tool definitions that the model is allowed to call.

    [
  { "type": "function", "name": "get_weather" }
]

    type string (required)

    The type of tool configuration. Fixed as allowed_tools.

    temperature float (optional)

    The sampling temperature, which controls the diversity of the generated text.

    Higher values make the output more random and diverse, while lower values make it more focused and deterministic.

    Value range: [0, 2)

    Both temperature and top_p control the diversity of the generated text. We recommend using only one of these parameters at a time. For more information, see Overview.

    top_p float (optional)

    The probability threshold for top-p sampling, which controls the diversity of the generated text.

    Higher values make the output more random and diverse, while lower values make it more focused and deterministic.

    Value range: (0, 1.0]

    Both temperature and top_p control the diversity of the generated text. We recommend using only one of these parameters at a time. For more information, see Overview.

    enable_thinking boolean (optional)

    Enables or disables reasoning mode. When enabled, the model performs a reasoning step before it responds. The reasoning process is returned as an output item of type reasoning. When enabling reasoning mode, we recommend also enabling built-in tools to achieve the best results on complex tasks.

    Valid values:

    • true: Enables reasoning mode.

    • false: Disables reasoning mode.

    For default values for different models, see Supported models.

    This parameter is not a standard OpenAI parameter. In the Python SDK, pass it using extra_body={"enable_thinking": True}. In the Node.js SDK and curl, use enable_thinking: true as a top-level parameter. We recommend using reasoning.effort instead, as enable_thinking will be deprecated.

    reasoning object (optional)

    Controls the model's reasoning effort. The model performs a reasoning step before replying, and the reasoning process is returned through an output item of type reasoning.

    Properties

    effort string (optional): The level of reasoning effort. Defaults to medium.

    • none: Disables reasoning and provides a direct answer.

    • minimal: Minimizes reasoning for the fastest response.

    • medium (default): Moderate reasoning, balancing speed and depth.

    • high: Deep reasoning, optimized for complex and professional tasks.

    • high: In-depth analysis for complex, specialized problems.

    reasoning.effort takes precedence over enable_thinking. We recommend using reasoning.effort, as enable_thinking will be deprecated.

    ocr_options object (optional)

    OCR built-in task parameters. Only applicable to the qwen3.5-ocr model. Use this parameter to call built-in OCR tasks (such as information extraction and text localization). Built-in task results are returned in the ocr_result field of the response.

    This parameter is not a standard OpenAI parameter. In the Python SDK, pass it using extra_body={"ocr_options": {...}}. In the Node.js SDK and curl, use ocr_options as a top-level parameter.

    Streaming output returns a series of JSON objects. Each object includes a type field to specify the event type and a sequence_number field to indicate the event order. The response.completed event marks the end of the stream.

    type string

    The event type identifier. Possible values include:

    • response.created: The response is created, with a status of queued.

    • response.in_progress: The response starts processing, and the status changes to in_progress.

    • response.output_item.added: A new output item (e.g., a message or a web_extractor_call) is added to the output array. When item.type is web_extractor_call, this indicates the start of a web extraction tool call.

    • response.content_part.added: A new content part is added to the content array of an output item.

    • response.output_text.delta: An incremental text segment is generated. This event is triggered multiple times, and the delta field contains the new text segment.

    • response.output_text.done: Text generation for a content part is complete. The text field contains the full text.

    • response.content_part.done: A content part is complete. The part object contains the complete content part.

    • response.output_item.done: An output item is complete. The item object contains the complete output item. When item.type is web_extractor_call, this indicates the completion of a web extraction tool call.

    • response.reasoning_summary_text.delta: (In reasoning mode) Provides an incremental update to the reasoning summary. The delta field contains the new segment.

    • response.reasoning_summary_text.done: (In reasoning mode) The reasoning summary is complete. The text field contains the full summary.

    • response.web_search_call.in_progress / searching / completed: An event that indicates a change in the search status when the web_search tool is used.

    • response.code_interpreter_call.in_progress / interpreting / completed: An event for a change in the code execution status (when using the code_interpreter tool).

    • Note: The web_extractor tool does not have a dedicated event type identifier. Its tool calls are passed through the general response.output_item.added and response.output_item.done events and are identified by the item.type field with a value of web_extractor_call.

    • response.mcp_call_arguments.delta / response.mcp_call_arguments.done: These events provide the delta and completion status for MCP call arguments.

    • response.mcp_call.completed: The MCP service call is complete.

    • response.file_search_call.in_progress / searching / completed: Status change events for a knowledge base search (when you use the file_search tool).

    • Note: When using the web_search_image and image_search tools, there are no dedicated intermediate state events. Tool calls are communicated through the response.output_item.added (call start) and response.output_item.done (call complete) events.

    • response.completed: The response generation is complete. The response object contains the full response, including usage. This event marks the end of the stream.

    sequence_number integer

    The event sequence number, starting at 0 and incrementing with each event. Use this number to process events in the correct order.

    response object

    The response object. Appears in the response.created, response.in_progress, and response.completed events. In the response.completed event, it contains the complete response data (including output and usage), and its structure is identical to the non-streaming Response object.

    item object

    An output item object. It appears in the response.output_item.added and response.output_item.done events. In the added event, it is an initial skeleton where the content is an empty array. In the done event, it is a complete object.

    Properties

    id string

    A unique identifier for the output item (e.g., msg_xxx).

    type string

    The type of the output item. Possible values: message, reasoning, web_search_call, web_search_image_call (text-to-image search), image_search_call (image-to-image search), mcp_call (MCP call), file_search_call (knowledge base search).

    role string

    The message role, which is always assistant. Present only when type is message.

    status string

    Generation status. In an added event, the status is in_progress, and in a done event, it is completed.

    content array

    An array of message content. In the added event, the array is empty []. In the done event, it contains complete content part objects whose structure is the same as that of the part object.

    part object

    The content part object. Appears in the response.content_part.added and response.content_part.done events.

    Properties

    type string

    The type of the content part, which is always output_text.

    text string

    Text content. This is an empty string in the added event and the complete text in the done event.

    annotations array

    An array of text annotations. Usually an empty array.

    logprobs object | null

    Token log probabilities. This field currently always returns null.

    delta string

    The incremental text segment. This field appears in the response.output_text.delta event and contains the newly added text segment. Concatenate all delta values to reconstruct the full text.

    text string

    The complete text content. This field appears in the response.output_text.done event. You can use it to validate the text reconstructed from the delta fragments.

    item_id string

    The unique identifier for the output item. Use this ID to correlate events that belong to the same item.

    output_index integer

    The index of the output item in the output array.

    content_index integer

    The index of the content part in the content array.

    summary_index integer

    The index of the item in the summary array of a reasoning output item. This field appears in the response.reasoning_summary_text.delta and response.reasoning_summary_text.done events.

    FAQ

    Q: How do I pass context for a multi-turn conversation?

    A: When making a new conversation request, pass the id from the model's previous successful response as the previous_response_id parameter.

    Q: Why are some fields in the response example not described in this topic?

    A: The official OpenAI SDK may output extra fields defined by the OpenAI protocol. Our service does not support these fields, so they are typically null. Focus only on the fields described in this topic.
