Why this result

Claude Opus 4.8 is clearly ahead on the provisional aggregate, 84 to 45. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Claude Opus 4.8's sharpest advantage is in knowledge, where it averages 62.7 against 49.9. The single biggest benchmark swing on the page is GPQA, 93.6% to 43.4%.

Claude Opus 4.8 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 Soofi S 30B-A3B. That is roughly Infinityx on output cost alone. Claude Opus 4.8 is the reasoning model in the pair, while Soofi S 30B-A3B 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.
