GPT-4.1 is clearly ahead on the provisional aggregate, 58 to 36. 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 knowledge, where it averages 66.3 against 65.6. The single biggest benchmark swing on the page is GPQA, 58.6% to 66.3%.
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 Gemma 4 E4B. That is roughly Infinityx on output cost alone. Gemma 4 E4B 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 128K for Gemma 4 E4B.
GPT-4.1 is ahead on BenchLM's provisional leaderboard, 58 to 36. The biggest single separator in this matchup is GPQA, where the scores are 58.6% and 66.3%.
GPT-4.1 has the edge for knowledge tasks in this comparison, averaging 66.3 versus 65.6. Inside this category, GPQA is the benchmark that creates the most daylight between them.
