We’ve released two new Realtime models for building low-latency voice and multimodal experiences: gpt-realtime-2.1 and gpt-realtime-2.1-mini.

With this release, we’ve also reduced p95 latency by at least 25% across Realtime voice models through improved caching.
gpt-realtime-2.1 updates GPT-Realtime-2 with improved alphanumeric recognition, silence and noise handling, and interruption behavior. It supports speech-to-speech interactions with configurable reasoning effort, instruction following, and tool use for more complex voice-agent workflows.
gpt-realtime-2.1-mini is a mini reasoning model for faster, lower-cost realtime voice interactions.
A quick way to choose:
Use gpt-realtime-2.1 when you want the strongest realtime reasoning, tool use, instruction following, and voice-agent behavior.
Use gpt-realtime-2.1-mini when you want a faster, more cost-efficient option for realtime voice experiences.
