}

Multimodal content in user requests.

Variants

CachePoint

Prompt-cache boundary after the preceding content block.

The marker is not model-visible content. A TTL is optional because providers such as Anthropic use per-point 5m/1h TTLs, while OpenAI GPT-5.6 uses a request-wide 30m policy.

Fields

ttl: Option<CachePointTtl>

Optional provider-compatible per-point TTL.

Text

Plain text.

Fields

text: String

Text content.

ImageUrl

Image by URL.

Fields

url: String

Image URL.

FileUrl

Generic file by URL and media type.

Fields

url: String

File URL.

media_type: String

File media type.

Binary

Inline binary media bytes.

Fields

data: Vec<u8>

Binary payload.

media_type: String

Declared or corrected media type.

ResourceRef

Resource-backed media reference.

Fields

uri: String

Resource URI.

media_type: String

Resource media type.

resource_type: String

Resource type, such as image, video, or document.

metadata: Metadata

Resource metadata.

DataUrl

Inline data URL for adapters that accept data URLs.

Fields

data_url: String

Data URL payload.

media_type: String

Media type carried by the data URL.
