Why this result
DeepSeek V4 Pro is clearly ahead on the BenchAlign aggregate, 60.66 to 51.11. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
DeepSeek V4 Pro's sharpest advantage is in mathematics, where it averages 31.7 against 4.1. The single biggest benchmark swing on the page is SWE-bench Verified, 73.6% to 54.6%. GPT-4.1 does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $0.43 input / $0.87 output per 1M tokens for DeepSeek V4 Pro. That is roughly 9.2x on output cost alone.
