Chronos-2
onlineamazon/chronos-2120M params | 512 context | $0.5000 input | $1.50 output
Chronos-2 is Amazon's universal successor to the original Chronos family. The official card describes it as a 120M-parameter, T5-inspired encoder-only model that handles univariate, multivariate, and covariate-informed forecasting in a single architecture. It is the Chronos variant to choose when you need cross-learning across related series, native covariates, or broader zero-shot coverage than the earlier univariate-first checkpoints.
Model Classification
Family
Chronos-2
Type
time series foundation model
Pretrained time-series model exposed on TSFM.ai for zero-shot or few-shot forecasting workloads.
Resources
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
