GPT Realtime 2.1 Mini

by OpenAI

GPT Realtime 2.1 Mini, released in July 2026 alongside GPT Realtime 2.1, is a distilled reasoning model for realtime voice applications where response time and cost matter most. OpenAI says it recognizes alphanumeric strings better than GPT Realtime 2. It takes text, audio and image input and answers in text and audio, with a 128,000-token context window and up to 32,000 output tokens. Reasoning effort is configurable from minimal to xhigh. It supports function calling, which fits high-volume voice agents such as order status, scheduling and front-line support, with GPT Realtime 2.1 as the step up for harder conversations.
