A weather model that produces ten-day global forecasts in under a minute and beat the leading physics-based system on about ninety percent of the measures tested.
Where the human came in
Trained on four decades of reanalysis data from the European weather centre, published in Science with open code, and run alongside traditional forecasts by meteorologists who still make the call.
Why it is not slop
Useful in the plainest sense: earlier warnings of cyclones and extreme weather. The paper says what it cannot do, and the forecasters keep the responsibility.
