OpenAI launches GPT-Realtime-2 with advanced voice communication and 128K context window
OpenAI has launched GPT-Realtime-2, a voice model that combines GPT-5-class reasoning with a 128K tokens context window and the ability to interrupt conversations. The model achieved top results on Big Bench Audio and Conversational Dynamics benchmarks. OpenAI also introduced a Chrome plugin for Codex and GPT-5.5 with security access for cybersecurity work.
WHY IT MATTERS
Realtime voice AI with larger context and interruption capability makes voice interfaces significantly more natural and practically usable. This represents a qualitative leap for voice-based AI interaction that opens up new use cases beyond writing.
