Claude Opus 4.7 vs GPT-5.4 Pro

Pick Claude Opus 4.7 if you want the stronger benchmark profile. GPT-5.4 Pro only becomes the better choice if agentic is the priority or you need the larger 1.05M context window.

Claude Opus 4.7 finishes one point ahead on BenchLM's provisional leaderboard, 93 to 92. That is enough to call, but not enough to treat as a blowout. This matchup comes down to a few meaningful edges rather than one model dominating the board.

Claude Opus 4.7's sharpest advantage is in knowledge, where it averages 68.2 against 49. The single biggest benchmark swing on the page is BrowseComp, 79.3% to 89.3%. GPT-5.4 Pro does hit back in agentic, so the answer changes if that is the part of the workload you care about most.

GPT-5.4 Pro is also the more expensive model on tokens at $30.00 input / $180.00 output per 1M tokens, versus $5.00 input / $25.00 output per 1M tokens for Claude Opus 4.7. That is roughly 7.2x on output cost alone. GPT-5.4 Pro is the reasoning model in the pair, while Claude Opus 4.7 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 1M for Claude Opus 4.7.
