I found the captions on Figure 1 quite interesting.

> Average performance (%) across four agentic benchmarks improves consistently with increasing model Intelligence Index.

> Centralized and hybrid coordination generally yield superior scaling efficiency, suggesting that collaborative agentic structures amplify capability gains more effectively than individual scaling alone.

Then again, the deltas between SAS and best performing MAS approach are ~8%, so I can't help wonder if it's worth the extra cost, at least for the generation of models that was studied.
