NAME

Langertha::Content - Base role for canonical multimodal content blocks with cross-provider serialization

VERSION

version 0.503

SYNOPSIS

package Langertha::Content::Image;
use Moose;
with 'Langertha::Content';

sub to_openai    { ... }
sub to_anthropic { ... }
sub to_gemini    { ... }
sub to_responses { ... }
sub to_ollama    { ... }
sub to_lmstudio  { ... }

DESCRIPTION

Marker role for canonical content blocks that can be embedded inside the content arrayref of a chat message and serialized to any provider wire format by Langertha::Role::Chat.

Implementations must provide to_openai, to_anthropic and to_gemini, and may provide to_responses, to_ollama and to_lmstudio (one per "content_format" in Langertha::Role::Chat). Each returns what its wire expects for the block: a HashRef for the message content / parts / input array, or (to_ollama) the raw base64 string for the message images array. The role's defaults for the last three croak with "<class> cannot be sent on the <fmt> wire; implement to_<fmt>".

to_responses

to_ollama

to_lmstudio

Default serializers for the responses, ollama and lmstudio "content_format" in Langertha::Role::Chats. They croak; a content class that can be sent on those wires overrides them (Langertha::Content::Image does).
