What is chronos-bolt-base?

OMW evidence review3 Oct 2026

Open Model Weights records chronos-bolt-base as a 0.205293B-parameter time series forecasting open-weight model in the chronos-bolt family, with autogluon listed as the developer. The checked source repository provides 1 recognized weight artifact, format evidence for Safetensors and a verified context window of 2,048 tokens. Values that are not evidenced in the checked sources remain explicitly undisclosed or unknown.

The repository declares Apache-2.0. Commercial use allowed under Apache-2.0 conditions. Open Model Weights reports the checked license evidence and classification; this is not legal advice.

No base model is declared in the checked standard lineage metadata, so Open Model Weights does not infer one. In the checked repository, training or recipe evidence is present.

Weight memory, without pretending it is a deployment guarantee.

These bars visualize weight-only decimal-GB estimates. They exclude KV cache, activations, runtime overhead, optimizer state and sharding.

LINEAGE & PROVENANCE

What the checked sources disclose — and what they do not.

Open Model Weights does not infer a hidden base model or training corpus when the checked sources do not declare one.

RUNTIME SIGNALS

Compatibility claims stay attached to their evidence level.

Declared and model-card-mentioned runtimes are discovery signals. They are not treated as Open Model Weights runtime tests unless explicitly measured.
