Observed: scored from AI use recorded in the Anthropic Economic Index (June 2026 release), 0 of 8 tasks. Estimated: scored from the task's O*NET 30.3 work activity, 8 of 8. Importance is O*NET's 1 to 5 rating of how central the task is. Model tier is the lowest tier that can do the task under the published rubric; "No tier" marks hands-on work.
The model tier this role needs
A frontier-tier model or lower covers 46% of the role's importance-weighted task work. 46% of the work is something AI can address at some tier, and 54% is hands-on.
Efficient, standard and frontier tiers come from the JobRoute model tier reference. The recommended tier is the lowest one that covers 80% of the work AI can address. How the method works.
