GPT-4o vs GPT-4o mini

Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.

Sibling matchup inside the GPT-4o family.

GPT-4o and GPT-4o mini sit in the same GPT-4o family. This page is less about two unrelated model lineages and more about how the siblings trade off on benchmark shape, token costs, and practical limits like context window.

GPT-4o is clearly ahead on the aggregate, 60 to 43. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-4o is also the more expensive model on tokens at $2.50 input / $10.00 output per 1M tokens, versus $0.15 input / $0.60 output per 1M tokens for GPT-4o mini. That is roughly 16.7x on output cost alone.

Quick Verdict

GPT-4o makes more sense if you want this variant’s specific profile, while GPT-4o mini is the cleaner fit if coding is the priority or you want the cheaper token bill.
