chronos-bolt-base and chronos-2 are both time-series-forecasting models. See each entry for specifics.
Chronos-Bolt-Base is the base-size variant of Amazon's improved Chronos forecasting model series, using a T5 encoder-decoder architecture. The Bolt series improves training efficiency over the original Chronos through revised architectural choices, achieving better forecast accuracy at equivalent model sizes. Apache 2.0 licensed.
AutoGluon's distribution of Amazon's Chronos-2 time-series foundation model, packaged for use within the AutoGluon machine learning framework. The model uses a T5 encoder-decoder over quantized time-series tokens for zero-shot forecasting across diverse domains. AutoGluon wraps it in a high-level API for automated time-series modeling pipelines.
