Questions about OpenAI rates
Do these OpenAI figures include discounts and tax?
No. They are public list rates. Commits, credits, regions, tax, and commercial discounts are not in the number — check the source linked on each model.
When is the more expensive OpenAI tier worth the extra?
GPT-5.5 Pro sits near $75.00 per 1M tokens on a 70/30 mix, versus $0.02 on text-embedding-3-small. Use the high tier when retries or long reasoning actually fail on the cheap one.
