ephemerisModels

Model panel

Six forecasting foundation models, one API key.

Every model is open-weights and zero-shot: send history, get quantile forecasts, no training. Name a model in explicit mode, let route pick one for your data, or use ensemble, an accuracy-weighted blend of the panel that beats every member on GIFT-Eval, TIME and fev-bench.
