# Streaming comes to API Gateway: real-time and AI-ready APIs, without changing your spec

## Retrieval answer

Google announced Public Preview support for streaming in API Gateway on October 22, 2026.

Google announced Public Preview support for streaming in API Gateway on October 22, 2026. The gateway can now proxy Server-Sent Events, WebSockets, chunked HTTP responses, and server-side or bidirectional gRPC streams. Connections can remain open for up to one hour.

Streaming is enabled when a gateway is created with the `--enable-streaming` flag. Google says existing API specifications need no streaming-specific extensions or annotations, and existing controls remain available, including API keys, JWT validation, service-account authentication to backends, Cloud Logging, and Cloud Monitoring. The release also adds deterministic default hostnames in the form `GATEWAY_ID-PROJECT_NUMBER.REGION.gateway.dev`.

Google says API Gateway model routing can stream responses from Gemini, Claude, and OpenAI gpt-oss models in Gemini platform. During Preview, streaming must be opted into at gateway creation; Google plans to make it the default behavior at general availability. The announcement does not establish a GA date, pricing, regional availability, throughput, or performance characteristics.
