Chronos-Bolt (Mini)
onlineamazon/chronos-bolt-mini21M params | 2K context | $0.00025 per forecast
Chronos-Bolt Mini is a compact 21M parameter checkpoint in Amazon's Chronos-Bolt family. It sits between the Tiny and Small variants, offering a better accuracy-latency tradeoff for moderate-volume forecasting workloads. Uses the same direct multi-step quantile prediction as the rest of the Chronos-Bolt line.
Model Classification
Family
Chronos
Type
time series foundation model
Pretrained time-series model exposed on TSFM.ai for zero-shot or few-shot forecasting workloads.
Resources
Training Data
Nearly 100B time-series observations from large public corpora and synthetic pretraining data, as documented by the official Chronos-Bolt model cards.
Recommended For
- • Fast zero-shot probabilistic forecasting in production APIs
- • Teams replacing classic Chronos-T5 with lower latency inference
Strengths
- • Direct multi-step forecasting avoids autoregressive rollout cost
- • Strong default for quantile forecasts with lightweight serving
Limitations
- • Focused on forecasting rather than broader multi-task time-series work
- • Less natural fit when you need model behavior tuned around rich multivariate covariates
