About this model

gpt-realtime-mini is OpenAI's low-cost live speech-to-speech model. Connect to WS /v1/realtime, stream 24 kHz PCM microphone audio in and get spoken replies back with low latency, using the OpenAI Realtime event format. Supports function tools and input transcription with gpt-4o-mini-transcribe. Billed by the text and audio tokens each reply uses, so silence costs nothing.
