GPT Realtime

GPT-Realtime combines speech recognition, language reasoning, and text-to-speech in one model so conversations flow at call-like speed. You can stream audio or text in, optionally include images or screenshots, and receive partial transcripts, incremental tokens, or live speech out with precise timing. The model keeps session memory, follows instructions reliably, and uses function calls to search, fetch data, or trigger actions in loop. Outputs can be schema-true JSON when automation needs strict formats, and barge-in, turn-taking, and endpoint controls keep dialog natural. Designed for production, it balances accuracy with tight round-trip times, making it a strong base for voice agents, customer support, real-time copilots, and accessibility experiences that must respond quickly without giving up grounded reasoning.
