    }
  2. | Url_image of {

Sourcetype anthropic_message = {
  1. role : [ `User | `Assistant ];
  2. content : anthropic_content list;
}

Extract system messages with their per-message provider_options and return remaining messages. The order matches the input.

Sourceval system_to_json : ?validator:Ai_provider_anthropic__.Cache_control_validator.t -> (string * Ai_provider.Provider_options.t) list -> Yojson.Basic.t option

Build the wire JSON for the system field on the Anthropic request. Returns None when no system messages are present. Always emits the array-of-blocks form (one text block per system message), matching upstream @ai-sdk/anthropic's convertToAnthropicPrompt.

Sourceval convert_messages : ?validator:Ai_provider_anthropic__.Cache_control_validator.t -> Ai_provider.Prompt.message list -> anthropic_message list

Convert SDK messages to Anthropic format with message grouping for alternating user/assistant roles. Pass ~validator to share the 4-breakpoint budget with system_to_json and the tools conversion.

Sourceval anthropic_content_to_json : anthropic_content -> Yojson.Basic.t

Serialize a content block to JSON.

Sourceval anthropic_message_to_json : anthropic_message -> Yojson.Basic.t

Serialize a message to JSON.
