Chronos 2 Update Jun 5, 2026: ☁️ Deploy Chronos 2 on AWS with AutoGluon Cloud. Real time, serverless, or batch inference in 3 lines of code — pandas DataFrames in, forecasts out. Check out the new deployment guide. Chronos 2 is a 120M parameter, encoder only time series foundation model for zero shot forecasting. It supports univariate , multivariate , and covariate informed tasks within a single architecture. Inspired by the T5 encoder, Chronos 2 produces multi step ahead quantile forecasts and uses a group attention mechanism for efficient in context learning across related series and covariates. Trained on a combination of real world and large scale synthetic datasets, it achieves state of the art zero shot accuracy among public models on fev bench , GIFT Eval , and Chronos Benchmark II . Chronos 2 is also highly efficient , delivering over 300 time series forecasts per second on a single A10G GPU and supporting both GPU and CPU inference .
