You should probably look at the cost/score graph by effort level instead:

It is most of the pareto frontier.
Not disputing the increase in quality, just stating that non-cherry-picked benchmarks show it is more verbose at Max effort
replyso don't use it at max? The benchmarks suggest that high/xhigh are more than sufficient to be ahead and a whole magnitude below max with regards to token usage. I'd treat that as an outlier and not how verbose the model is in general (QED I know)
replyIs verboseness the only measure of token efficiency towards overall task completion?
replyDisagree.
Our internal company tests showed a cost per task drop from 0.35usd to 0.16usd . Opus 5low vs opus 5.5 low
replyVery fast you were.
replyEven created an account to tell us just that.
replyI don't think so, I typically use Opus 5 on High, and 5.5 scores lower on token use:
