We introduce TabPFN-3.5, our new flagship Tabular Foundation Model.
It significantly outperforms its predecessor, TabPFN-3, and all existing baselines across a broad range of tabular problems.
TabPFN-3.5 Achievements
TabPFN-3.5 sets a new state of the art on standard tabular prediction in TabArena, and extends it to the data practitioners encounter in practice:
- non-i.i.d. data with temporal or grouped splits
- tables with strings, text and images
- high-cardinality categorical features
- wide tables with many features
These gains carry over to our task-specific harnesses:
- state of the art on relational data
- stronger time-series forecasting
For faster inference, our variant TabPFN-3.5-Fast runs up to 3x faster than TabPFN-3 while keeping most of the accuracy gains.
In addition, we upgrade TabPFN-3.5-Plus, expanding our multimodal capabilities with advanced text and date handling alongside proprietary inference optimizations.
New Features and Improvements
Finally, we release a new version of our Thinking mode, TabPFN-3.5-Thinking, which scales inference-time computation to push the state of the art further.
It benefits from our stronger base model and from inference-time improvements that make it up to 12x faster than TabPFN-3-Thinking.
