AssistantResponseFormatOption = :auto | ResponseFormatText { type } | ResponseFormatJSONObject { type } | ResponseFormatJSONSchema { json_schema, type }

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 the following:
AssistantResponseFormatOption = :auto

auto is the default value

class ResponseFormatText { type }

Default response format. Used to generate text responses.

type: :text

The type of response format being defined. Always text.

class ResponseFormatJSONObject { type }

JSON object response format. An older method of generating JSON responses. Using json_schema is recommended for models that support it. Note that the model will not generate JSON without a system or user message instructing it to do so.

type: :json_object

The type of response format being defined. Always json_object.

class ResponseFormatJSONSchema { json_schema, type }

JSON Schema response format. Used to generate structured JSON responses. Learn more about Structured Outputs.

json_schema: { name, description, schema, strict}

Structured Outputs configuration options, including a JSON Schema.

name: String

The name of the response format. Must be a-z, A-Z, 0-9, or contain underscores and dashes, with a maximum length of 64.

description: String

A description of what the response format is for, used by the model to determine how to respond in the format.

schema: Hash[Symbol, untyped]

The schema for the response format, described as a JSON Schema object. Learn how to build JSON schemas here.

strict: bool

Whether to enable strict schema adherence when generating the output. If set to true, the model will always follow the exact schema defined in the schema field. Only a subset of JSON Schema is supported when strict is true. To learn more, read the Structured Outputs guide.

type: :json_schema

The type of response format being defined. Always json_schema.

class AssistantToolChoice { type, function }

AssistantToolChoiceOption = :none | :auto | :required | AssistantToolChoice { type, function }

Controls which (if any) tool is called by the model. none means the model will not call any tools and instead generates a message. auto is the default value and 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. Specifying a particular tool like {"type": "file_search"} or {"type": "function", "function": {"name": "my_function"}} forces the model to call that tool.

One of the following:
Auto = :none | :auto | :required

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.
