Configure streaming for LLM responses and other traffic You can now create API Gateway gateways that stream requests and responses instead of buffering them

## Feature Feature **Configure streaming for LLM responses and other traffic** You can now create API Gateway gateways that stream requests and responses instead of buffering them. This Public Preview feature supports incremental response delivery over HTTP/2 or HTTP/1.1 chunked transfer encoding, Server-Sent Events (SSE), WebSockets, and gRPC bidirectional streaming. A common use is streaming token-by-token responses from a large language model (LLM). To enable streaming, create a gateway with the `--enable-streaming` flag. The streaming mode is fixed when you create the gateway and can't be changed later.
