Chronos 2 Small Alternatives

chronos-2 is an open-source model for time series forecasting, enabling users to predict future values based on historical data. It is suitable for data scientists and researchers in business, finance, and scientific domains.

Chronos 2 is a time series forecasting foundation model hosted on Hugging Face. It belongs to the class of pretrained models for sequential data prediction and addresses the need to forecast future values from historical time series. The model produces probabilistic forecasts through specified quantiles. It accepts context data in pandas DataFrame format and supports configurable prediction lengths along with identification of multiple series via an item identifier column. Users load it through the dedicated Chronos library with a single constructor call that can target GPU acceleration. Chronos 2 carries an Apache-2.0 license. It is distributed as open-source weights in Safetensors format on the Hugging Face platform, where it can be accessed via the chronos-forecasting Python package or compatible inference tools. The repository references two associated arXiv papers that describe its development. It is provided by Amazon and forms part of a broader collection of time series forecasting foundation models.

Chronos-T5 (Mini) is a time series foundation model hosted on Hugging Face under the autogluon organization. It belongs to the class of pretrained models for time series forecasting and is based on the T5 architecture for text2text-generation tasks applied to time series data. The model carries tags for time series forecasting, transformers, safetensors, and foundation models. Its associated papers are listed as arxiv:2403.07815 and arxiv:1910.10683. An update note indicates that related Chronos-Bolt and original Chronos models became available on Amazon SageMaker JumpStart in February 2025. It is delivered as a model repository on Hugging Face that can be loaded through the Transformers library. Example code shows importing AutoTokenizer and AutoModelForSeq2SeqLM, then instantiating the tokenizer and model directly from the repository identifier with an option for automatic device mapping. Notebooks for Google Colab and Kaggle are referenced for further usage examples. The license is apache-2.0. The repository provides files and versions along with instructions for use with libraries, inference providers, notebooks, and local applications.

Chronos T5 Tiny is a time series forecasting model hosted on Hugging Face. It forms part of the Chronos family of pretrained foundation models for time series data and is based on the T5 architecture. The model supports probabilistic forecasting by generating predictions at specified quantile levels. It accepts historical data in pandas DataFrame format and produces forecasts for a user-defined number of future steps. Integration occurs through the dedicated Chronos library, which provides a BaseChronosPipeline class for loading the model and running inference. Usage begins with installation of the chronos-forecasting package followed by loading the model with a device mapping such as CUDA for GPU acceleration. An example workflow reads a CSV file containing time series records, then calls predict_df with parameters for prediction length, quantile levels, and an identifier column. The model card lists it under the Apache 2.0 license and references two arXiv papers that describe its development. It is delivered as a downloadable model repository on the Hugging Face platform, with associated Safetensors weights and instructions for libraries, inference providers, notebooks, and local applications. The repository is maintained under the Amazon organization on Hugging Face.

Chronos Bolt Small is a time series forecasting model hosted on Hugging Face. It belongs to the Chronos family of pretrained foundation models for time series data and produces probabilistic forecasts through specified quantiles. The model is provided as a safetensors checkpoint under the apache-2.0 license. It can be loaded through the Chronos library with a single line of Python code that accepts a pandas DataFrame of historical values and returns predictions for a chosen number of future steps. Example code demonstrates loading the model onto a CUDA device, reading a CSV context file, and calling predict_df with parameters for prediction length, quantile levels such as 0.1 0.5 and 0.9, and an item identifier column. The repository lists it among time series foundation models and references two arXiv papers. It is made available by Amazon for use with standard inference tools on the Hugging Face platform. No pricing information appears because the model is distributed as an open-source artifact.

Chronos Bolt Tiny is a time series forecasting model hosted on Hugging Face. It belongs to the class of pretrained foundation models for time series and is made available by Amazon under the apache-2.0 license. The model uses the t5 architecture and is distributed in safetensors format. It supports probabilistic forecasting by producing outputs at specified quantile levels. Integration occurs through the Chronos library, which supplies a BaseChronosPipeline class for loading the model and generating predictions from pandas dataframes. Usage begins with installation of the chronos-forecasting package followed by creation of a pipeline object that can target cuda devices. The pipeline accepts a context dataframe containing historical observations, a prediction length parameter that defines how many future steps to forecast, a list of quantile levels such as 0.1 0.5 and 0.9, and an identifier column name. An example workflow loads the AirPassengers dataset from a public S3 bucket and calls predict_df to obtain a forecast dataframe. The repository lists related arxiv papers 1910.10683 and 2403.07815 that describe the underlying research. It is one of several chronos variants offered for time series foundation model tasks.

Chronos-t5-large is a large time series foundation model developed by Amazon. It uses a T5-based architecture pretrained on massive amounts of time series data to enable zero-shot forecasting. The model outputs probabilistic predictions with quantiles and can be used via the dedicated Chronos Python library or standard Hugging Face interfaces.

Chronos T5 Mini is a pretrained time series foundation model hosted on Hugging Face. Developed by Amazon, it belongs to the class of time series forecasting foundation models and is based on the T5 architecture. The model generates probabilistic forecasts from historical time series data. It accepts context data via a pandas dataframe, produces multi-step predictions, and returns specified quantiles such as 0.1, 0.5, and 0.9. A simple pipeline interface handles loading the model, preparing input, and generating output in a few lines of code. It is delivered as a model repository on the Hugging Face platform. Users install the companion chronos-forecasting Python package and instantiate BaseChronosPipeline.from_pretrained with the identifier amazon/chronos-t5-mini. The pipeline supports device mapping including CUDA for accelerated inference. Example usage loads a CSV file containing passenger data and forecasts 36 steps ahead while estimating the requested quantiles. The model card lists it under the Apache-2.0 license. It is accompanied by references to two arXiv papers that describe the underlying methods. The repository provides safetensors weights and is tagged for time-series, foundation-models, and pretrained use.

Kronos is an open-source decoder-only foundation model trained specifically on financial candlestick (K-line) data from over 45 global exchanges. The mini variant is designed for time series forecasting in finance. It includes a specialized tokenizer that converts OHLCV data into discrete tokens and supports fine-tuning on custom market data.
