Looking at the graph, it would appear there's an implicit "today" in that statement, as they do appear poised to equal or surpass Sonnet 4.5 on that same benchmark in the near future.

What Cursor is really emphasizing here is speed — they’re claiming it runs about four times faster than GPT-5/Sonnet, while still offering roughly the same level of performance.

Does anyone code with GPT-5? I've never had it work in Cursor. I mean, like, at all.

A lot of people use it! It scores very well on our benchmarks, significantly better than Composer-1.
