Google announced that API Gateway's streaming support has entered public preview. According to the Google Developers Blog, SSE, chunked transfer, WebSocket, and gRPC streaming endpoints can share the same gateway and policies with existing APIs, with no changes needed to API specifications. Streams can stay open for up to one hour; during the preview period it must be enabled when creating a gateway, and existing gateways cannot be converted in place. Combined with model routing, clients can use a single OpenAI-compatible endpoint to dispatch to Gemini, Claude, and OpenAI gpt-oss models based on the model field in the request and return responses as a stream. The gateway's default domain is changed to a fixed format composed of the gateway ID, project number, and region, which can be written into the configuration before creation. This support is currently in public preview.
