Profile note
The commercial Swiss counterpart to ECMWF's public AIFS: a private physics foundation model (EPT-2) sold as a weather API to energy traders and utilities, with a REST API exposing 25+ models and Apache Arrow support. Pricing is per simulation run, an unusual unit worth recording — $0.20-15 per run versus €1,000-20,000 for classical NWP.
