GPT-5.4 Pro vs Moonshot v1

Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.

GPT-5.4 Pro is clearly ahead on the aggregate, 94 to 51. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-5.4 Pro's sharpest advantage is in coding, where it averages 89 against 33.3. The single biggest benchmark swing on the page is LiveCodeBench, 86 to 21.

GPT-5.4 Pro is the reasoning model in the pair, while Moonshot v1 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-5.4 Pro gives you the larger context window at 1.05M, compared with 128K for Moonshot v1.

Quick Verdict

Pick GPT-5.4 Pro if you want the stronger benchmark profile. Moonshot v1 only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
