media.image.variant

Create a variant of an existing StorageObject image via the org AI connection; persist and return a new StorageObject UUID. Prefer media_profile_uuid (fail-closed). gpt-image-* uses images/edits fallback (variations API unsupported).

Input Schema

Field	Type	Required	Default	Description
organization_uuid	string	Yes	—	—
media_profile_uuid	string	No	—	Preferred ready MediaProfile; fills AI + storage binding
ai_provider_config_uuid	string	No	—	Filled from MediaProfile resolution; provenance only
connection_uuid	string	No	—	Back-compat when no MediaProfile
storage_connection_uuid	string	No	—	—
bucket	string	No	—	—
source_storage_object_uuid	string	Yes	—	—
prompt	string	No	—	Optional variation guidance. Required path for gpt-image-* (falls back to images/edits). Default prompt used when omitted.
model	string	No	—	—
size	string	No	—	—
key	string	No	—	—
register_artifact	boolean	No	—	Default true — write GeneratedArtifact after put
review_gate	string	No	—	—
brand	string	No	—	—
campaign	string	No	—	—
purpose	string	No	—	—
session_uuid	string	No	—	When set, also stamp agents.cost-entry-record unit=image
variant_of_uuid	string	No	—	Parent GeneratedArtifact UUID. When omitted, resolved from source_storage_object_uuid if an artifact owns that object.
produced_by_kind	string	No	—	—
produced_by_uuid	string	No	—	—
created_by_uuid	string	No	—	—
