Map of field name to typed field spec.

Show child attributes
The text to read from. May be empty only when the request carries image assets.
Assets keyed by reference string. Write a reference wherever the asset belongs in state or a field instructions; every asset must be referenced at least once. A state that is exactly the sole asset's key carries no text of its own and is read as file-only. A model that reads either text or a document per request, not both (ScaleDown Extract with a PDF), needs that form: any other text around the key is state text and is rejected with 400.

Example:
{ "allow_fallbacks": true }
ISO date that anchors dates written without a year.
Pattern:
^\d{4}-\d{2}-\d{2}$A unique identifier for grouping related requests (e.g., a conversation or agent workflow). Used for observability grouping in Broadcast and private logging; never sent to the provider. If provided in both the request body and the x-session-id header, the body value takes precedence. Maximum of 256 characters.
Maximum string length:
256Example:
"session-1234"
Metadata for observability and tracing. Known keys (trace_id, trace_name, span_name, generation_name, parent_span_id) have special handling. Additional keys are passed through as custom metadata to configured broadcast destinations.
