Gateway mirrors upstream 4.0.75: default /v4/ai base URL, AI_GATEWAY_API_KEY/VERCEL_OIDC_TOKEN auth, team scoping, protocol/auth-method headers, versioned user-agent suffix, language/embedding/image/video/reranking/speech/transcription aliases, durable Batch V4 start/status/results with ordered mixed content, callback URL forwarding, reconciled nonnegative native request counts, typed not_found errors, Tako Search, async-video start/status and native callback registration, unary transcription plus duplex streaming transcription, and a callable experimental transcription factory that mints short-lived route-bound tokens. Gateway providerOptions cover BYOK, routing order/fallbacks, provider allow-lists, prompt-training restrictions, has filtering, sort, serviceTier, quota, and tags; response/provider metadata, model/credits/spend/generation APIs, retryable structured errors, and provider tools are retained. Full realtime model sessions, Vercel o11y headers, metadata-cache refresh policy, ProviderV4 type names, ESM-only packaging, Node 22 engines, and workflow serialization helpers remain JS/runtime-only gaps.
Factory argument requirements are defined by the public Swift factory signatures. Use Public symbols when you need the exact initializer or factory declaration.
