- Added new handlers: AudioHelper, ImageHelper, EmbeddingHelper, and ResponsesHelper to manage respective requests. - Updated ModelMappedHelper to accept request parameters for better model mapping. - Enhanced error handling and validation across new handlers to ensure robust request processing. - Introduced support for new relay formats in relay_info and updated relevant functions accordingly.
