 **Two findings stand out.** Darwin-Prediction-Weather has the lowest error at every forecast lead, 14 to 38 percent below the next model. Among the models from national and international weather centres, the AI model ECMWF AIFS leads the physics-based ECMWF IFS at every lead, by 6 to 15 percent.

 For daily maximum temperature in 2026, the leading weather-centre model has an error of about 2.4 °C at 7 days, against about 1.35 °C at 1 day. Darwin-Prediction-Weather records about 2.1 °C at 7 days and 0.84 °C at 1 day.
 
 **What is Darwin-Prediction-Weather?**
-VIDRAFT's weather prediction system. Its forecast engine applies local bias correction and skill-weighted fusion to global forecasts. On the WeatherBench 2 deterministic protocol for 2020 it records the lowest error in all 15 evaluated cells (2 m temperature, 500 hPa geopotential, 850 hPa temperature at 1, 3, 5, 7 and 10 days). See the [model page](https://huggingface.co/FINAL-Bench/Darwin-Prediction-Weather) and the [WeatherBench 2 forecast files](https://huggingface.co/datasets/VIDraft/Darwin-Prediction-Weather-WB2).
