WebSocket

OpenAI released v3.1.0 of its Python client library, adding support for a new 'Ultrafast' tier, WebSocket stream IDs, and structured MCP/WebSocket error handling. The release also formally deprecates the Sora video API and strips out remaining Stainless SDK-generation infrastructure.

Amazon SageMaker AI has launched bidirectional streaming support for real-time inference, enabling WebSocket-based voice applications through vLLM integration. The feature uses HTTP/2 on port 8443 to bridge client connections with vLLM's Realtime API, allowing audio to stream in while transcription streams back simultaneously over a single persistent connection.
