llama.cpp Release b11780 Introduces Realtime Transcription API
Llama.cpp release b11780 adds a new realtime transcription API with WebSocket support to its built-in server. This update introduces dedicated session management and stream handling for audio processing workflows. This enhancement significantly expands the native capabilities of the llama.cpp server for audio applications and real-time speech processing. It allows developers to build responsive voice-enabled AI systems directly on top of local inference infrastructure. The update implements authentication via WebSocket handshakes, keeps realtime slots isolated from the main prompt loop to prevent resource starvation, and follows the GA Realtime schema for transcription sessions.
## BACKGROUND
llama.cpp is a popular open-source software library designed to perform inference on large language models locally using efficient hardware utilization. WebSockets provide a full-duplex communication channel over a single TCP connection, enabling real-time bidirectional data transfer between clients and servers.
