But why is the question, I run about 400k models every 30 minutes at work. I have tried all other approaches, but xgboost model per timeseries has never been beaten before. Even if I wasn't targetting accuracy, Xgboost loading a pretrained model and predicting with it and still faster.
Are they very stationary time series with not very changing dynamics over time?
Have you tried the latest TSFMs? Research (even in 2025) shows they outperform XGBoost models in certain scenarios. https://www.sciencedirect.com/science/article/pii/S266682702...
