The standard response format from OpenAI’s Responses API.

Fields

id: String

The ID of a completion response.

object: ResponseObject

The type of the object.

created_at: u64

The time at which a given response has been created, in seconds from the UNIX epoch (01/01/1970 00:00:00).

status: ResponseStatus

The status of the response.

error: Option<ResponseError>

Response error (optional)

incomplete_details: Option<IncompleteDetailsReason>

Incomplete response details (optional)

instructions: Option<String>

System prompt/preamble

max_output_tokens: Option<u64>

The maximum number of tokens the model should output

model: String

The model name

provider_reasoning: Option<String>

Provider-specific top-level reasoning content returned by some OpenAI-compatible Responses implementations.

reasoning_metadata: Option<Map<String, Value>>

The complete object-shaped top-level reasoning metadata returned by the provider.

Unknown fields, unknown values, and null-valued members inside the object are preserved value-equivalently. A top-level null, missing field, or unsupported non-object shape is normalized to no reasoning metadata. When serializing manually constructed responses, Self::provider_reasoning takes precedence over this field, and this field takes precedence over Self::reasoning_context.

reasoning_context: Option<String>

The effective reasoning context returned by OpenAI.

This is populated as a convenience projection of Self::reasoning_metadata. String-shaped reasoning returned by compatible providers remains available through Self::provider_reasoning.

usage: Option<ResponsesUsage>

Token usage

output: Vec<Output>

The model output (messages, etc will go here)

tools: Vec<ResponsesToolDefinition>

Tools

additional_parameters: AdditionalParameters

Additional parameters
