      Hi Windy team,

      I just read that ECMWF announced the introduction of an AI based weather forecast, called AIFS ENS:

      https://www.ecmwf.int/en/about/media-centre/news/2025/ecmwfs-ensemble-ai-forecasts-become-operational

      I was wondering if Windy has plans to also make this available in the app?

      Cheers
      Andy

        @Space_Andy This would be a great addition to the Windy platform. +1

        "Major gains
        The new ensemble model outperforms state-of-the-art physics-based models for many measures, including surface temperature, with gains of up to 20%. At the moment, it works at a lower resolution (31 km) than the physics-based ensemble system (9 km), which remains indispensable for high-resolution fields and coupled Earth-system processes.

        ECMWF is therefore also exploring hybrid systems that leverage the strengths of both approaches.

        The high-accuracy ensemble model complements the portfolio of ECMWF services by using the opportunities made available by machine learning (ML) and artificial intelligence (AI).

        The AIFS ENS relies on physics-based data assimilation to generate the initial conditions. However, it can generate forecasts over 10 times faster than the physics-based forecasting system, while reducing energy consumption by approximately 1,000 times."
