AssemblyAI transcription mirrors upstream 3.0.36: ASSEMBLYAI_API_KEY, custom headers, versioned user-agent suffix, transcription/transcriptionModel aliases, /v2/upload plus /v2/transcript submit/poll flow, legacy best via speech_model, current universal-3-5-pro/universal-3-pro/universal-2 via speech_models, deprecation and migration warnings, providerOptions.assemblyai schema including Universal 3 Pro and GA nested options, millisecond-to-second word segment conversion, audio-intelligence provider metadata, raw final response metadata, AssemblyAI error schema, and unsupported language/embedding/image families. ProviderV4, ESM-only packaging, Node 22 engines, and workflow serialization helpers are JS-only upstream concerns.
Factory argument requirements are defined by the public Swift factory signatures. Use Public symbols when you need the exact initializer or factory declaration.
