o3-pro and o4-mini-high don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only o3-pro has a verified first-party API price: $20.00 per million input tokens and $80.00 per million output tokens. No pay-as-you-go API rate is tracked for o4-mini-high. o4-mini-high shipped 55 days before o3-pro, so benchmark comparisons should account for the intervening progress.
