Machine Learning Five Questions About Chronos-2, the Time Series Foundation Model Part 1: A practitioner's walkthrough of univariate, multivariate, covariate-informed, and cold-start forecasting. Shuai Guo May 29, 2026 22 min read Share Created by GPT Image 2 Foundation models are now mainstream. We first saw them in language, then vision, and now also in video and speech. The recipe by now is familiar: first, pretrain a big neural net on large enough data, then apply the model to downstream tasks without any per-task adaptation. For many industrial applications, time series is a crucial modality. We frequently need to do forecasting, anomaly detection, and classification by using different kinds of recording data.
