All models are LLM-based or LLM-empowered for time series tasks.

All models released official GitHub code (at least training/inference code).

Most models focus on forecasting; a few also cover classification, anomaly detection, or multi-modal retrieval.

The latest trend is foundation modeling and cross-modal learning for time series using LLMs.
