OpenAI releases GPT-Realtime-2, described as a GPT-5-level reasoning audio model
OpenAI released GPT-Realtime-2 alongside Realtime-Translate and Realtime-Whisper, with a 128K context window, five reasoning-effort levels, and API pricing of $32 per million input tokens and $64 per million output tokens.
Why it matters: HKR-H/K/R all pass: realtime audio reasoning is a strong hook; 128K context, five reasoning levels, and $32/$64 per 1M tokens add substance; voice-agent cost and stack choices hit practitioners. This is a same-day OpenAI product update.
