The benchmark includes 20 expert-written tasks, from weekly activity updates to after-action reports and program status reports. Each requires models to turn working files into a finished report for a reader with specific priorities and little time. Scores ranged from 54.3% to 64.1%, with Gemini 4 Argon scoring highest. Models handled basic formatting well. Deciding what to include and explaining what the facts mean together accounted for 67–77% of each model’s lost points.
