Tests show that enabling the "Attention-kind" output style for Opus 5 reduces output length by 43% while maintaining a 97% pass rate on coding tasks. The style increases the rate of answering in the first line from 3% to 75%, and 88% of outputs contain deliverables only. This sparks discussion about shifting from Human-Computer Interaction (HCI) to AI-Human Interaction (AHI).
