Pick Grok 4.3 if you want the stronger benchmark profile. GPT-4.1 only becomes the better choice if knowledge is the priority or you would rather avoid the extra latency and token burn of a reasoning model.

Pick Grok 4.3 if you want the stronger benchmark profile. GPT-4.1 only becomes the better choice if knowledge is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
Grok 4.3 is clearly ahead on the provisional aggregate, 79 to 58. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $1.25 input / $2.50 output per 1M tokens for Grok 4.3. That is roughly 3.2x on output cost alone. Grok 4.3 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.
Grok 4.3 is ahead on BenchLM's provisional leaderboard, 79 to 58. The biggest single separator in this matchup is GPQA, where the scores are 66.3% and 90.1%.
GPT-4.1 has the edge for knowledge tasks in this comparison, averaging 66.3 versus 53.9. Inside this category, GPQA is the benchmark that creates the most daylight between them.
GPT-4.1 has the edge for coding in this comparison, averaging 54.6 versus 47.3. Grok 4.3 stays close enough that the answer can still flip depending on your workload.
GPT-4.1 has the edge for instruction following in this comparison, averaging 87.4 versus 81.3. Grok 4.3 stays close enough that the answer can still flip depending on your workload.
