Evidence and review: Deployed; confidence: unassessed; source-checked; legacy source check. Legacy source check; no named human reviewer is recorded in this projection.

## The human problem

Forecasters need reliable tools beyond research demonstrations.

## The prior constraint

ECMWF used its established physics-based forecasting system.

## AI’s actual role

AIFS added machine-learned predictions to the operational toolkit.

## The documented result

AIFS began running alongside the physics-based IFS on 25 February 2025.

## Why it may matter

Forecast users gained an additional operational source of guidance.

## Limitations

Deployment is not a guarantee of superiority for every variable, place, or event.

## Unresolved questions

Compare performance continuously and improve forecast use.
