Tabular data remains a complex challenge in Deep Learning.

TabPFN[1] (based on Prior-Data Fitted Networks) is a DL model for tabular data. Its latest version, TabPFN-v2[2], has been repurposed as TabPFN-TS[3] for time-series forecasting.

The model is open-source and shows strong potential—its research team recently secured €9 million in funding from investors like Hugging Face.

TabPFN-v2 made headlines as a model pretrained entirely on tabular synthetic data yet seamlessly repurposed for time-series forecasting. It outperformed other foundation models and ranked first on the GIFT-Eval benchmark!

Key characteristics of TabPFN-TS:

  • Foundation Model: Trained on diverse synthetic tabular datasets, enabling strong generalization to unseen data.

  • In-Context Learning: Adapts dynamically in a single forward pass based on dataset structure and relationships.

  • Efficiency: Just 11M parameters—outperforming much larger models like Chronos-Large (710M parameters).

  • Simplicity: It uses only basic calendar features, avoiding complex lagged or rolling transformations. Supports exogenous variables.

This article demonstrates how to use TabPFN-TS and includes a minimal benchmark comparing it with other models.
