Pick GPT-4.1 mini if you want the stronger benchmark profile. GPT-4o only becomes the better choice if its workflow or ecosystem matters more than the raw scoreboard.
Confidence note. This is a partial-evidence comparison with 13 shared benchmark results across 7 evidence categories; 1 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
GPT-4.1 mini has the cleaner BenchAlign overall profile here, landing at 43.1 versus 40.73. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
GPT-4.1 mini's sharpest advantage is in mathematics, where it averages 4.5 against 0.3. The single biggest benchmark swing on the page is FrontierMath v2 (Tiers 1-3), 4.483% to 0.345%.
GPT-4o is also the more expensive model on tokens at $2.50 input / $10.00 output per 1M tokens, versus $0.40 input / $1.60 output per 1M tokens for GPT-4.1 mini. That is roughly 6.3x on output cost alone. GPT-4.1 mini gives you the larger context window at 1M, compared with 128K for GPT-4o.
