    Type Alias ImagePart

    ImagePart:
        | { attachmentKey?: never; content: string; mimeType: string }
        | { attachmentKey: string; content?: never; mimeType: string }

    Represents an image attached to an LLM chat model message, carrying exactly one of inline content or an attachmentKey. Supplying neither or both is rejected by the tagger, and the union keeps both shapes from type-checking.

        Key of an already-uploaded image, in place of inline content

      • Optionalcontent?: never
