Chronos-2

AutoGluon v1.5 adds support for Chronos-2, our latest generation of foundation models for time series forecasting. Chronos-2 natively handles all types of dynamic covariates, and performs cross-learning from items in the batch. It produces multi-step quantile forecasts and is designed for strong out-of-the-box performance on new datasets.

Chronos-2 achieves state-of-the-art zero-shot accuracy among public models on major benchmarks such as fev-bench and GIFT-Eval, making it a strong default choice when little or no task-specific training data is available.

In AutoGluon, Chronos-2 can be used in zero-shot mode or fine-tuned on custom data. Both LoRA fine-tuning and full fine-tuning are supported. Chronos-2 integrates into the standard TimeSeriesPredictor workflow, making it easy to backtest, compare against classical and deep learning models, and combine with other models in ensembles.

:::python
from autogluon.timeseries import TimeSeriesPredictor

predictor = TimeSeriesPredictor(...)
predictor.fit(train_data, presets="chronos2")  # zero-shot mode

More details on zero-shot usage, fine-tuning and ensembling are available in the updated tutorial.

TimeSeries

AutoGluon v1.5 introduces substantial improvements to the time series module, with clear gains in both accuracy and usability. Across our benchmarks, v1.5 achieves up to an 80% win rate compared to v1.4. The release adds new models, more flexible ensembling options, and numerous bug fixes and quality-of-life improvements.

Highlights

• Chronos-2 is now available in AutoGluon, with support for zero-shot inference as well as full and LoRA fine-tuning (tutorial).
• Customizable ensembling logic: Adds item-level ensembling, multi-layer stack ensembles, and other advanced forecast combination methods (documentation).
• New presets leading to major gains in accuracy & efficiency. AG-TS v1.5 achieves up to 80% win rate over v1.4 on point and probabilistic forecasting tasks. With just a 10 minute time limit, v1.5 outperforms v1.4 running for 2 hours.
• Usability improvements: Automatically determine an appropriate backtesting configuration by setting num_val_windows="auto" and refit_every_n_windows="auto". Easily access the validation predictions and perform rolling evaluation on custom data with new predictor methods backtest_predictions and backtest_targets.
