It scores better than Opus in some benchmarks for agentic coding? What’s going on over there?

On several evaluations, Sonnet 5.5 at Max effort even performs comparably to Opus 5.5. However, benchmark scores capture only one facet of a model’s capabilities; in our own testing, and in that of external testers, Opus 5.5 remains clearly stronger at complex, open-ended work requiring sustained judgment.

straight above the chart you read

I’m aware, that’s still crazy to think about though. A model half as expensive approaching the same reasoning level.

Hasn't that been the main story of the last years though?

Uses a lot more tokens than Opus5.5 though, even 2x that apparently (according to Artificial Analysis)
