Pick Interfaze Beta if you want the stronger benchmark profile. GPT-4.1 only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
Interfaze Beta is clearly ahead on the provisional aggregate, 76 to 58. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Interfaze Beta's sharpest advantage is in knowledge, where it averages 89.9 against 66.3. The single biggest benchmark swing on the page is GPQA, 66.3% to 89.9%.
GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $1.50 input / $3.50 output per 1M tokens for Interfaze Beta. That is roughly 2.3x on output cost alone. Interfaze Beta 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.
Interfaze Beta is ahead on BenchLM's provisional leaderboard, 76 to 58. The biggest single separator in this matchup is GPQA, where the scores are 66.3% and 89.9%.
Interfaze Beta has the edge for knowledge tasks in this comparison, averaging 89.9 versus 66.3. Inside this category, GPQA is the benchmark that creates the most daylight between them.
