CreateMessageRequest

object
* Additional properties are NOT allowed.
rolestringrequired

The role of the entity that is creating the message. Allowed values include:

  • user: Indicates the message is sent by an actual user and should be used in most cases to represent user-generated messages.
  • assistant: Indicates the message is generated by the assistant. Use this value to insert messages from the assistant into the conversation.

Allowed values:userassistant

contentOne Of
required
Text contentstring

The text contents of the message.

attachmentsarray[object]

A list of files attached to the message, and the tools they should be added to.

Show Child Parameters
metadataobject

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.

Example

CreateModerationRequest

object
inputOne Of
required

Input (or inputs) to classify. Can be a single string, an array of strings, or
an array of multi-modal input objects similar to other models.

Variant 1string

A string of text to classify for moderation.

Default:

Example:I want to kill them.

modelAny Of

The content moderation model you would like to use. Learn more in
the moderation guide, and learn about
available models here.

Default:omni-moderation-latest

Example:omni-moderation-2024-09-26

Variant 1string
Example

CreateModerationResponse

object

Represents if a given text input is potentially harmful.

idstringrequired

The unique identifier for the moderation request.

modelstringrequired

The model used to generate the moderation results.

resultsarray[object]required

A list of moderation objects.

Example

CreateRunRequest

object
* Additional properties are NOT allowed.
assistant_idstringrequired

The ID of the assistant to use to execute this run.

modelAny Of

The ID of the Model to be used to execute this run. If a value is provided here, it will override the model associated with the assistant. If not, the model associated with the assistant will be used.

Example:gpt-4o

Variant 1string
reasoning_effortstring

o1 and o3-mini models only

Constrains effort on reasoning for
reasoning models.
Currently supported values are low, medium, and high. Reducing
reasoning effort can result in faster responses and fewer tokens used
on reasoning in a response.

Allowed values:lowmediumhigh

Default:medium

instructionsstring

Overrides the instructions of the assistant. This is useful for modifying the behavior on a per-run basis.

additional_instructionsstring

Appends additional instructions at the end of the instructions for the run. This is useful for modifying the behavior on a per-run basis without overriding other instructions.

additional_messagesarray[object]

Adds additional messages to the thread before creating the run.

* Additional properties are NOT allowed.
Show Child Parameters
toolsOne Of
array

Override the tools the assistant can use for this run. This is useful for modifying the behavior on a per-run basis.

metadataobject

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.

temperaturenumber

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.

Default:1

>= 0<= 2

Example:1

top_pnumber

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.

Default:1

>= 0<= 1

Example:1

streamboolean

If true, returns a stream of events that happen during the Run as server-sent events, terminating when the Run enters a terminal state with a data: [DONE] message.

max_prompt_tokensinteger

The maximum number of prompt tokens that may be used over the course of the run. The run will make a best effort to use only the number of prompt tokens specified, across multiple turns of the run. If the run exceeds the number of prompt tokens specified, the run will end with status incomplete. See incomplete_details for more info.

>= 256

max_completion_tokensinteger

The maximum number of completion tokens that may be used over the course of the run. The run will make a best effort to use only the number of completion tokens specified, across multiple turns of the run. If the run exceeds the number of completion tokens specified, the run will end with status incomplete. See incomplete_details for more info.

>= 256

truncation_strategyobject

Controls for how a thread will be truncated prior to the run. Use this to control the intial context window of the run.

Show Child Parameters
tool_choiceOne Of
AssistantsApiToolChoiceOptionstring

none means the model will not call any tools and instead generates a message. auto means the model can pick between generating a message or calling one or more tools. required means the model must call one or more tools before responding to the user.

Allowed values:noneautorequired

parallel_tool_callsboolean

Whether to enable parallel function calling during tool use.

Default:true

response_formatOne Of
AssistantsApiResponseFormatOptionstring

auto is the default value

Allowed values:auto
