How ratings work
Every job on Hughie shows a rating for its occupation. The ratings come from a 2025 study by the International Labour Organization (ILO).
How the ILO measured exposure
The ILO asked 1,640 workers to rate how far generative AI could automate 2,861 work tasks, then compared their answers with a panel of international experts. It used those answers to build an AI model that scores the tasks of every occupation in ISCO-08, the international list of occupations. Then it sorted the occupations into six levels.
The six exposure levels
| ILO exposure level | Occupations | Listed on Hughie |
|---|---|---|
| Not exposed | 231 | Yes |
| Minimal | 84 | Yes |
| Gradient 1 | 17 | Yes |
| Gradient 2 | 44 | No |
| Gradient 3 | 38 | No |
| Gradient 4 | 13 | No |
The counts cover the 427 occupations in the ILO's published scores. Gradient 1 is the lowest of the four exposed levels, and gradient 4 is the highest. A count of occupations is not a count of jobs.
What a rating means
A rating estimates how exposed an occupation's tasks are to generative AI. It does not predict whether a particular job will disappear. Even the lowest level is not a promise that a job is AI-proof.
