How this price is scoped: OpenAI prices this model per 1M tokens on three separate modalities: text at $4.00 input / $0.40 cached input / $24.00 output, audio at $32.00 / $0.40 / $64.00, and image input at $5.00 / $0.50. The tracked figures are the TEXT rates, which is how GPT-Realtime-2 is tracked too, so the two rows compare like for like. Every text and audio rate is identical to GPT-Realtime-2; only the model generation differs.
Price receipt
