Query parameters

  • limit integer

    A limit on the number of objects to be returned. Limit can range between 1 and 100, and the default is 20.

    Default value is 20.

  • order string

    Sort order by the created_at timestamp of the objects. asc for ascending order and desc for descending order.

    Values are asc or desc. Default value is desc.

  • after string

    A cursor for use in pagination. after is an object ID that defines your place in the list. For instance, if you make a list request and receive 100 objects, ending with obj_foo, your subsequent call can include after=obj_foo in order to fetch the next page of the list.

  • before string

    A cursor for use in pagination. before is an object ID that defines your place in the list. For instance, if you make a list request and receive 100 objects, starting with obj_foo, your subsequent call can include before=obj_foo in order to fetch the previous page of the list.

        Maximum length is 512.

      • model string Required

        ID of the model to use. You can use the List models API to see all of your available models, or see our Model overview for descriptions of them.

      • instructions string | null Required

        The system instructions that the assistant uses. The maximum length is 256,000 characters.

        Maximum length is 256000.

      • tools array[object] Required

        A list of tool enabled on the assistant. There can be a maximum of 128 tools per assistant. Tools can be of types code_interpreter, file_search, or function.

        Not more than 128 elements. Default value is [] (empty).

      • tool_resources object | null

        A set of resources that are used by the assistant's tools. The resources are specific to the type of tool. For example, the code_interpreter tool requires a list of file IDs, while the file_search tool requires a list of vector store IDs.

          • file_ids array[string]

            A list of file IDs made available to the code_interpreter` tool. There can be a maximum of 20 files associated with the tool.

            Not more than 20 elements. Default value is [] (empty).

            The ID of the vector store attached to this assistant. There can be a maximum of 1 vector store attached to the assistant.

            Not more than 1 element.

      • metadata object | null Required

        Set of 16 key-value pairs that can be attached to an object. This can be useful for storing additional information about the object in a structured format, and querying for objects via API or the dashboard.

        Keys are strings with a maximum length of 64 characters. Values are strings with a maximum length of 512 characters.

        • * string Additional properties
      • temperature number | null

        What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.

        Minimum value is 0, maximum value is 2. Default value is 1.

      • top_p number | null

        An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.

        We generally recommend altering this or temperature but not both.

        Minimum value is 0, maximum value is 1. Default value is 1.

      • response_format string | null | object

        Specifies the format that the model must output. Compatible with GPT-4o, GPT-4 Turbo, and all GPT-3.5 Turbo models since gpt-3.5-turbo-1106.

        Setting to { "type": "json_schema", "json_schema": {...} } enables Structured Outputs which ensures the model will match your supplied JSON schema. Learn more in the Structured Outputs guide.

        Setting to { "type": "json_object" } enables JSON mode, which ensures the message the model generates is valid JSON.

        Important: when using JSON mode, you must also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if finish_reason="length", which indicates the generation exceeded max_tokens or the conversation exceeded the max context length.

        One of:
        string-1 string | null ResponseFormatText object | null ResponseFormatJsonObject object | null ResponseFormatJsonSchema object | null

        auto is the default value

        Value is auto.
