GPT-4.1 is clearly ahead on the provisional aggregate, 58 to 32. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-4.1's sharpest advantage is in coding, where it averages 54.6 against 53.3. The single biggest benchmark swing on the page is SWE-bench Verified, 54.6% to 68.2%.
GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Laguna XS.2. That is roughly Infinityx on output cost alone. Laguna XS.2 is the reasoning model in the pair, while GPT-4.1 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. GPT-4.1 gives you the larger context window at 1M, compared with 131K for Laguna XS.2.
GPT-4.1 is ahead on BenchLM's provisional leaderboard, 58 to 32. The biggest single separator in this matchup is SWE-bench Verified, where the scores are 54.6% and 68.2%.
GPT-4.1 has the edge for coding in this comparison, averaging 54.6 versus 53.3. Inside this category, SWE-bench Verified is the benchmark that creates the most daylight between them.
