Chronos⚡️-Base

Chronos⚡️ (read: Chronos-Bolt) is a family of pretrained time series forecasting models which can be used for zero-shot forecasting. Chronos⚡️ models are based on the T5 architecture and are available in the following sizes.

Model	Parameters	Based on
chronos-bolt-tiny	9M	t5-efficient-tiny
chronos-bolt-mini	21M	t5-efficient-mini
chronos-bolt-small	48M	t5-efficient-small
chronos-bolt-base	205M	t5-efficient-base

Usage

Chronos⚡️ models will be available in the next stable release of AutoGluon, so the following instructions will only work once AutoGluon 1.2 has been released.

A minimal example showing how to perform zero-shot inference using Chronos⚡️ with AutoGluon:

pip install autogluon

from autogluon.timeseries import TimeSeriesPredictor, TimeSeriesDataFrame

df = TimeSeriesDataFrame("https://autogluon.s3.amazonaws.com/datasets/timeseries/m4_hourly/train.csv")

predictor = TimeSeriesPredictor(prediction_length=48).fit(
    df,
    hyperparameters={
        "Chronos": {"model_path": "autogluon/chronos-bolt-base"},
    },
)

predictions = predictor.predict(df)
