Current flagship mid tier
Email me when GPT-Realtime-2 gets cheaper
Availability: OpenAI released the newer GPT-Realtime-2.1 on 2026-07-06, but it did not retire this model: GPT-Realtime-2 is still on OpenAI's rate card at the same prices, still listed in its model index, and it appears in none of the shutdown tables on OpenAI's deprecations page. The two generations are sold side by side at identical text and audio rates, so this row is current rather than superseded.
