File

@Serializable

@SerialName(value = "file")

data class File(val mediaType: String, val base64: String = "", val filename: String? = null, val providerMetadata: Map<String, JsonElement>? = null, val url: String? = null) : ContentPart

File content — payload data the model produced or that's attached to a turn. Per historical parity gap #38, mirrors v6's richer FilePart.data. Currently base64 is the only data shape; a URL-shaped variant lives in Source. filename is the user-facing label (Anthropic models produce it for artifact-like outputs; v6 has a dedicated slot for it).

Constructors

File

constructor(mediaType: String, base64: String = "", filename: String? = null, providerMetadata: Map<String, JsonElement>? = null, url: String? = null)

Properties

base64

val base64: String

filename

val filename: String?

Optional display name. v6 calls this filename.

mediaType

val mediaType: String

metadata

val ContentPart.metadata: Map<String, JsonElement>?

providerMetadata

val providerMetadata: Map<String, JsonElement>?

url

val url: String?

Remote (or data) URL for the file content, when not provided inline as base64. Mirrors v6's data: DataContent | URL. Resolve with convertToLanguageModelPrompt for providers that don't accept URLs.

Functions

inline fun <T> ContentPart.providerMetadataAs(provider: String): T?

fun <T> ContentPart.providerMetadataAs(provider: String, serializer: KSerializer<T>): T?
