# Large Time-Series Model (Timer)

[Large time-series model](https://cloud.tsinghua.edu.cn/f/b766629dbc584a4e8563/) introduced in this [paper](https://arxiv.org/abs/2402.02368) and enhanced with our [further work](https://arxiv.org/abs/2410.04803).

The base version is pre-trained on **260B** time points, which supports zero-shot forecasting ([benchmark](https://cdn-uploads.huggingface.co/production/uploads/64fbe24a2d20ced4e91de38a/n2IW7fTRpuZFMYoPr1h4O.png)) and adaptations.

See this [Github Page](https://github.com/thuml/Large-Time-Series-Model) for examples of using this model.

## Acknowledgments

Timer is mostly built from the Internet public time series dataset, which comes from different research teams and providers. We sincerely thank all individuals and organizations who have contributed the data. Without their generous sharing, this model would not have existed.
