Input priceWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it. | $10.00 | — |
Output priceWhat you pay for the text the model writes back. It is normally the dearer half: producing an answer costs more than reading one. | $30.00 | — |

GPT-4 Turbo and o3-mini-high don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only GPT-4 Turbo has a verified first-party API price: $10.00 per million input tokens and $30.00 per million output tokens. No pay-as-you-go API rate is tracked for o3-mini-high. GPT-4 Turbo shipped 452 days before o3-mini-high, so benchmark comparisons should account for the intervening progress.
Context windows are 128k (GPT-4 Turbo) vs 200k (o3-mini-high).
