Why this result
Claude 4.1 Opus has the cleaner BenchAlign overall profile here, landing at 44.8 versus 43.1. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Claude 4.1 Opus's sharpest advantage is in coding, where it averages 74.5 against 23.6. The single biggest benchmark swing on the page is SWE-bench Verified, 74.5% to 23.6%.
Claude 4.1 Opus is also the more expensive model on tokens at $15.00 input / $75.00 output per 1M tokens, versus $0.40 input / $1.60 output per 1M tokens for GPT-4.1 mini. That is roughly 46.9x on output cost alone. GPT-4.1 mini gives you the larger context window at 1M, compared with 200K for Claude 4.1 Opus.
