Claude Opus 4.6 is clearly ahead on the provisional aggregate, 91 to 71. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Claude Opus 4.6's sharpest advantage is in agentic, where it averages 72.6 against 45.3. The single biggest benchmark swing on the page is BrowseComp, 83.7% to 52%. GLM-4.7 does hit back in coding, so the answer changes if that is the part of the workload you care about most.
Claude Opus 4.6 is also the more expensive model on tokens at $5.00 input / $25.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for GLM-4.7. That is roughly Infinityx on output cost alone. GLM-4.7 is the reasoning model in the pair, while Claude Opus 4.6 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. Claude Opus 4.6 gives you the larger context window at 1M, compared with 200K for GLM-4.7.
Claude Opus 4.6 is ahead on BenchLM's provisional leaderboard, 91 to 71. The biggest single separator in this matchup is BrowseComp, where the scores are 83.7% and 52%.
