Highlights

AutoGluon-Tabular is the state of the art in the AutoML Benchmark 2025!

The AutoML Benchmark 2025, an independent large-scale evaluation of tabular AutoML frameworks, showcases AutoGluon 1.2 as the state of the art AutoML framework! Highlights include:

• AutoGluon's rank statistically significantly outperforms all AutoML systems via the Nemenyi post-hoc test across all time constraints.
• AutoGluon with a 5 minute training budget outperforms all other AutoML systems with a 1 hour training budget.
• AutoGluon is pareto efficient in quality and speed across all evaluated presets and time constraints.
• AutoGluon with presets="high", infer_limit=0.0001 (HQIL in the figures) achieves >10,000 samples/second inference throughput while outperforming all methods.
• AutoGluon is the most stable AutoML system. For "best" and "high" presets, AutoGluon has 0 failures on all time budgets >5 minutes.

AutoGluon Multimodal's "Bag of Tricks" Update

We are pleased to announce the integration of a comprehensive "Bag of Tricks" update for AutoGluon's MultiModal (AutoMM). This significant enhancement substantially improves multimodal AutoML performance when working with combinations of image, text, and tabular data. The update implements various strategies including multimodal model fusion techniques, multimodal data augmentation, cross-modal alignment, tabular data serialization, better handling of missing modalities, and an ensemble learner that integrates these techniques for optimal performance.

Users can now access these capabilities through a simple parameter when initializing the MultiModalPredictor after following the instruction here to download the checkpoints:

from autogluon.multimodal import MultiModalPredictor
predictor = MultiModalPredictor(label="label", use_ensemble=True)
predictor.fit(train_data=train_data)

We express our gratitude to @zhiqiangdon, for this substantial contribution that enhances AutoGluon's capabilities for handling complex multimodal datasets. Here is the corresponding research paper describing the technical details: Bag of Tricks for Multimodal AutoML with Image, Text, and Tabular Data.

Deprecations and Breaking Changes

The following deprecated TabularPredictor methods have been removed in the 1.3.0 release (deprecated in 1.0.0, raise in 1.2.0, removed in 1.3.0). Please use the new names:

• persist_models -> persist, unpersist_models -> unpersist, get_model_names -> model_names, get_model_best -> model_best, get_pred_from_proba -> predict_from_proba, get_model_full_dict -> model_refit_map, get_oof_pred_proba -> predict_proba_oof, get_oof_pred -> predict_oof, get_size_disk_per_file -> disk_usage_per_file, get_size_disk -> disk_usage, get_model_names_persisted -> model_names(persisted=True)

The following logic has been deprecated starting in 1.3.0 and will log a FutureWarning. Functionality will be changed in a future release:

• (FutureWarning) TabularPredictor.delete_models() will default to dry_run=False in a future release (currently dry_run=True). Please ensure you explicitly specify dry_run=True for the existing logic to remain in future releases. @Innixma (#4905)

Loading models trained on older versions of AutoGluon is not supported. Please re-train models using AutoGluon 1.2.

For Tabular, we encompass the primary enhancements of the new TabPFNMix tabular foundation model and parallel fit strategy into the new "experimental_quality" preset to ensure a smooth transition period for those who wish to try the new cutting edge features. We will be using this release to gather feedback prior to incorporating these features into the other presets. We also introduce a new stack layer model pruning technique that results in a 3x inference speedup on small datasets with zero performance loss and greatly improved post-hoc calibration across the board, particularly on small datasets.

For TimeSeries, we introduce Chronos-Bolt, our latest foundation model integrated into AutoGluon, with massive improvements to both accuracy and inference speed compared to Chronos, along with fine-tuning capabilities. We also added covariate regressor support!

We are also excited to announce AutoGluon-Assistant (AG-A), our first venture into the realm of Automated Data Science.

AutoGluon Becomes the Golden Standard for Competition ML in 2024

Before diving into the new features of 1.2, we would like to start by highlighting the wide-spread adoption AutoGluon has received on competition ML sites like Kaggle in 2024. Across all of 2024, AutoGluon was used to achieve a top 3 finish in 15 out of 18 tabular Kaggle competitions, including 7 first place finishes, and was never outside the top 1% of private leaderboard placements, with an average of over 1000 competing human teams in each competition. In the $75,000 prize money 2024 Kaggle AutoML Grand Prix, AutoGluon was used by the 1st, 2nd, and 3rd place teams, with the 2nd place team led by two AutoGluon developers: Lennart Purucker and Nick Erickson! For comparison, in 2023 AutoGluon achieved only 1 first place and 1 second place solution. We attribute the bulk of this increase to the improvements seen in AutoGluon 1.0 and beyond.

We'd like to emphasize that these results are achieved via human expert interaction with AutoGluon and other tools, and often includes manual feature engineering and hyperparameter tuning to get the most out of AutoGluon. To see a live tracking of all AutoGluon solution placements on Kaggle, refer to our AWESOME.md ML competition section where we provide links to all solution write-ups.

AutoGluon-Assistant: Automating Data Science with AutoGluon and LLMs

We are excited to share the release of a new AutoGluon-Assistant module (AG-A), powered by LLMs from AWS Bedrock or OpenAI. AutoGluon-Assistant empowers users to solve tabular machine learning problems using only natural language descriptions, in zero lines of code with our simple user interface. Fully autonomous AG-A outperforms 74% of human ML practitioners in Kaggle competitions and secured a live top 10 finish in the $75,000 prize money 2024 Kaggle AutoML Grand Prix competition as Team AGA 🤖!

TabularPredictor presets="experimental_quality"

TabularPredictor has a new "experimental_quality" preset that offers even better predictive quality than "best_quality". On the AutoMLBenchmark, we observe a 70% winrate vs best_quality when running for 4 hours on a 64 CPU machine. This preset is a testing ground for cutting edge features and models which we hope to incorporate into best_quality for future releases. We recommend to use a machine with at least 16 CPU cores, 64 GB of memory, and a 4 hour+ time_limit to get the most benefit out of experimental_quality. Please let us know via a GitHub issue if you run into any problems running the experimental_quality preset.

TabPFNMix: A Foundation Model for Tabular Data

TabPFNMix is the first tabular foundation model created by the AutoGluon team, and was pre-trained exclusively on synthetic data.
The model builds upon the prior work of TabPFN and TabForestPFN. TabPFNMix to the best of our knowledge achieves a new state-of-the-art for individual open source model performance on datasets between 1000 and 10000 samples, and also supports regression tasks! Across the 109 classification datasets with less than or equal to 10000 training samples in TabRepo, fine-tuned TabPFNMix outperforms all prior models, with a 64% win-rate vs the strongest tree model, CatBoost, and a 61% win-rate vs fine-tuned TabForestPFN.

The model is available via the TABPFNMIX hyperparameters key, and is used in the new experimental_quality preset. We recommend using this model for datasets smaller than 50,000 training samples, ideally with a large time limit and 64+ GB of memory. This work is still in the early stages, and we appreciate any feedback from the community to help us iterate and improve for future releases. You can learn more by going to our HuggingFace model page for the model (tabpfn-mix-1.0-classifier, tabpfn-mix-1.0-regressor). Give us a like on HuggingFace if you want to see more! A paper is planned in future to provide more details about the model.

fit_strategy="parallel"

AutoGluon's TabularPredictor now supports the new fit argument fit_strategy and the new "parallel" option, enabled by default in the new experimental_quality preset. For machines with 16 or more CPU cores, the parallel fit strategy offers a major speedup over the previous "sequential" strategy. We estimate with 64 CPU cores that most datasets will experience a 2-4x speedup, with the speedup getting larger as CPU cores increase.

Chronos-Bolt⚡: a 250x faster, more accurate Chronos model

Chronos-Bolt is our latest foundation model for forecasting that has been integrated into AutoGluon. It is based on the T5 encoder-decoder architecture and has been trained on nearly 100 billion time series observations. It chunks the historical time series context into patches of multiple observations, which are then input into the encoder. The decoder then uses these representations to directly generate quantile forecasts across multiple future steps—a method known as direct multi-step forecasting. Chronos-Bolt models are up to 250 times faster and 20 times more memory-efficient than the original Chronos models of the same size.

The following plot compares the inference time of Chronos-Bolt against the original Chronos models for forecasting 1024 time series with a context length of 512 observations and a prediction horizon of 64 steps.

Chronos-Bolt models are not only significantly faster but also more accurate than the original Chronos models. The following plot reports the probabilistic and point forecasting performance of Chronos-Bolt in terms of the Weighted Quantile Loss (WQL) and the Mean Absolute Scaled Error (MASE), respectively, aggregated over 27 datasets (see the Chronos paper for details on this benchmark). Remarkably, despite having no prior exposure to these datasets during training, the zero-shot Chronos-Bolt models outperform commonly used statistical models and deep learning models that have been trained on these datasets (highlighted by *). Furthermore, they also perform better than other FMs, denoted by a +, which indicates that these models were pretrained on certain datasets in our benchmark and are not entirely zero-shot. Notably, Chronos-Bolt (Base) also surpasses the original Chronos (Large) model in terms of the forecasting accuracy while being over 600 times faster.

Chronos-Bolt models are now available through AutoGluon in four sizes—Tiny (9M), Mini (21M), Small (48M), and Base (205M)—and can also be used on the CPU. With the addition of Chronos-B...

TimeSeries

Highlights

AutoGluon 1.1 comes with numerous new features and improvements to the time series module. These include highly requested functionality such as feature importance, support for categorical covariates, ability to visualize forecasts, and enhancements to logging. The new release also comes with considerable improvements to forecast accuracy, achieving 60% win rate and 3% average error reduction compared to the previous AutoGluon version. These improvements are mostly attributed to the addition of Chronos, improved preprocessing logic, and native handling of missing values.

Tabular Performance Enhancements

AutoGluon 1.0 features major enhancements to predictive quality, establishing a new state-of-the-art in Tabular modeling. To the best of our knowledge, AutoGluon 1.0 marks the largest leap forward in the state-of-the-art for tabular data since the original AutoGluon paper from March 2020. The enhancements come primarily from two features: Dynamic stacking to mitigate stacked overfitting, and a new learned model hyperparameters portfolio via Zeroshot-HPO, obtained from the newly released TabRepo ensemble simulation library. Together, they lead to a 75% win-rate compared to AutoGluon 0.8 with faster inference speed, lower disk usage, and higher stability.

AutoML Benchmark Results

OpenML released the official 2023 AutoML Benchmark results on November 16th, 2023. Their results show AutoGluon 0.8 as the state-of-the-art in AutoML systems across a wide variety of tasks: "Overall, in terms of model performance, AutoGluon consistently has the highest average rank in our benchmark." We now showcase that AutoGluon 1.0 achieves far superior results even to AutoGluon 0.8!

Below is a comparison on the OpenML AutoML Benchmark across 1040 tasks. LightGBM, XGBoost, and CatBoost results were obtained via AutoGluon, and other methods are from the official AutoML Benchmark 2023 results. AutoGluon 1.0 has a 95%+ win-rate against traditional tabular models, including a 99% win-rate vs LightGBM and a 100% win-rate vs XGBoost. AutoGluon 1.0 has between an 82% and 94% win-rate against other AutoML systems. For all methods, AutoGluon is able to achieve >10% average loss improvement (Ex: Going from 90% accuracy to 91% accuracy is a 10% loss improvement). AutoGluon 1.0 achieves first place in 63% of tasks, with lightautoml having the second most at 12% (AutoGluon 0.8 previously took first place 48% of the time). AutoGluon 1.0 even achieves a 7.4% average loss improvement over AutoGluon 0.8!

Not only is AutoGluon more accurate in 1.0, it is also more stable thanks to our new usage of Ray subprocesses during low-memory training, resulting in 0 task failures on the AutoML Benchmark.

AutoGluon 1.0 is capable of achieving the fastest inference throughput of any AutoML system while still obtaining state-of-the-art results. By specifying the infer_limit fit argument, users can trade off between accuracy and inference speed to meet their needs.

As seen in the below plot, AutoGluon 1.0 sets the Pareto Frontier for quality and inference throughput, achieving Pareto Dominance compared to all other AutoML systems. AutoGluon 1.0 High achieves superior performance to AutoGluon 0.8 Best with 8x faster inference and 8x less disk usage!

You can get more details on the results here.

We are excited to see what our users can accomplish with AutoGluon 1.0's enhanced performance.
As always, we will continue to improve AutoGluon in future releases to push the boundaries of AutoML forward for all.

AutoGluon Multimodal (AutoMM) Highlights in One Figure

AutoMM Uniqueness

AutoGluon Multimodal (AutoMM) distinguishes itself from other open-source AutoML toolboxes like AutosSklearn, LightAutoML, H2OAutoML, FLAML, MLJAR, TPOT and GAMA, which mainly focus on tabular data for classification or regression. AutoMM is designed for fine-tuning foundation models across multiple modalities—image, text, tabular, and document, either individually or combined. It offers extensive capabilities for tasks like classification, regression, object detection, named entity recognition, semantic matching, and image segmentation. In contrast, other AutoML systems generally have limited support for image or text, typically using a few pretrained models like EfficientNet or hand-crafted rules like bag-of-words as feature extractors. AutoMM provides a uniquely comprehensive and versatile approach to AutoML, being the only AutoML system to support flexible multimodality and support for a wide range of tasks. A comparative table detailing support for various data modalities, tasks, and model types is provided below.

Highlights

• AutoGluon TimeSeries introduced several major improvements, including new models, upgraded presets that lead to better forecast accuracy, and optimizations that speed up training & inference.
• AutoGluon Tabular now supports calibrating the decision threshold in binary classification (API), leading to massive improvements in metrics such as f1 and balanced_accuracy. It is not uncommon to see f1 scores improve from 0.70 to 0.73 as an example. We strongly encourage all users who are using these metrics to try out the new decision threshold calibration logic.
• AutoGluon MultiModal introduces two new features: 1) PDF document classification, and 2) Open Vocabulary Object Detection.
• AutoGluon MultiModal upgraded the presets for object detection, now offering medium_quality, high_quality, and best_quality options. The empirical results demonstrate significant ~20% relative improvements in the mAP (mean Average Precision) metric, using the same preset.
• AutoGluon Tabular has added an experimental Zeroshot HPO config which performs well on small datasets <10000 rows when at least an hour of training time is provided (~60% win-rate vs best_quality). To try it out, specify presets="experimental_zeroshot_hpo_hybrid" when calling fit().
• AutoGluon EDA added support for Anomaly Detection and Partial Dependence Plots.
• AutoGluon Tabular has added experimental support for TabPFN, a pre-trained tabular transformer model. Try it out via pip install autogluon.tabular[all,tabpfn] (hyperparameter key is "TABPFN")! You can also try it out via specifying presets="experimental_extreme_quality".
