120M params | Upstream checkpoint

Chronos-2 is Amazon's universal successor to the original Chronos family, at 120M parameters. The official card frames it as a single model that handles univariate, multivariate, and covariate-informed forecasting in one architecture, a more general design than the univariate-first checkpoints of the first Chronos generation.

Under the hood it is a T5-inspired, encoder-only model that uses group attention and multi-step quantile decoding, so it can reason across related series and native covariates while emitting probabilistic forecasts directly. It is pretrained on a subset of Chronos Datasets, a subset of GIFT-Eval Pretrain, and synthetic univariate and multivariate data, as described by the official Chronos-2 card and technical report.

Model Classification

Family

Chronos-2

Type

time series foundation model

Pretrained time-series model for zero-shot or few-shot forecasting workloads.

Training Data

Subset of Chronos Datasets, subset of GIFT-Eval Pretrain, plus synthetic univariate and multivariate data as described by the official Chronos-2 card and technical report.

Recommended For

  • • Zero-shot forecasting with covariates or related multivariate series
  • • Teams that want one Chronos model for broader forecasting workloads

Strengths

  • • Handles univariate, multivariate, and covariate-aware forecasting in one family
  • • More universal design than the original first-generation Chronos checkpoints

Limitations

  • • Still a forecasting model, not a general multi-task representation backbone
  • • Larger deployment footprint than the smallest lightweight baselines
