When this model is cost-effective
gpt-realtime-2 ranks 8 of 9 OpenAI records by combined list price ($96.00 for 1M input plus 1M output tokens). That puts it in the higher-priced third of this provider's committed records.
Cached input reads are listed at $0.400 per 1M tokens, 1.3% of the fresh input rate, so repeated cached prompts have a lower committed input-token cost than fresh prompts.
No context window is committed for this record, so there is no long-context cost signal to apply.
