Chronos-Bolt (Mini)

Chronos-Bolt Mini is a compact 21M-parameter checkpoint in Amazon's Chronos-Bolt family. It sits one rung above Chronos-Bolt Tiny, trading a little extra capacity for a better accuracy-latency balance on moderate-volume forecasting workloads while staying firmly in the cost-efficient tier of the line.

Like the rest of Chronos-Bolt, it runs a patch-based T5 encoder-decoder and produces forecasts through direct multi-step quantile prediction rather than autoregressive token-by-token rollout, so it returns probabilistic forecasts in a single pass without the latency of the original Chronos generation. It is pretrained on nearly 100B time-series observations drawn from large public corpora and synthetic pretraining data, as documented by the official Chronos-Bolt model cards.

On TSFM.ai, Mini is the pick when Tiny feels too lean but you still want fast, low-cost zero-shot quantile forecasts at scale. Step up to Chronos-Bolt Small or Base when accuracy matters more than per-call cost, or move to Chronos-2 when your workload needs covariates or multivariate cross-learning rather than lightweight univariate throughput.
