Box Evaluation Finds Claude Opus 5.5 Used About One-Third As Many Tokens As Opus 5

A Box evaluation found Claude Opus 5.5 used about one-third as many tokens as Opus 5 on complex business tasks, adding task-level evidence as Anthropic lowered model costs. The assessment involved business tasks that required working across multiple documents. Opus 5.5 completed them 30% faster and produced deliverables 42% shorter than Opus 5, while maintaining accuracy in the evaluation. Those results describe performance in Box’s test, not Anthropic’s total token use. A separate tracked business sample showed token volume rising faster than spending over a similar period, but it does not establish that Opus 5.5 caused the change.
