This release supports Python versions 3.10, 3.11, 3.12 and 3.13. Support for Python 3.13 is currently experimental, and some features might not be available when running Python 3.13 on Windows. Loading models trained on older versions of AutoGluon is not supported. Please re-train models using AutoGluon 1.5.0.

Spotlight

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.

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.

Fixes and Improvements

Tabular

AutoGluon-Tabular v1.5 introduces several improvements focused on accuracy, robustness, and usability. The release adds new foundation models, updates the feature preprocessing pipeline, and improves GPU stability and memory estimation. New model portfolios are provided for both CPU and GPU workloads.

Highlights

  • New foundation models: RealTabPFN-2, RealTabPFN-2.5, and TabDPT are now available in AutoGluon-Tabular.

  • Updated preprocessing pipeline with more consistent feature handling across models.

  • Improved GPU stability and more reliable memory estimation during training.

  • New CPU and GPU portfolios tuned for better performance across a wide range of datasets.

  • Stronger benchmark results: with the new presets, AutoGluon-Tabular v1.5 achieves an 85% win rate over AutoGluon v1.4 Extreme on the 51 TabArena datasets, with a 3% reduction in mean relative error.

New Features

Fixes and Improvements

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.

New Features

API Changes and Deprecations

  • Remove outdated presets related to the original Chronos model: chronos, chronos_large, chronos_base, chronos_small, chronos_mini, chronos_tiny, chronos_ensemble. We recommend to use the new presets chronos2, chronos2_small and chronos2_ensemble instead.
