LimiX-2

A 400M-parameter model for tables that does classification, regression and missing-value filling, under a non-commercial licence

About LimiX-2

LimiX-2 is a tabular model built for structured data rather than text. Stable AI and Professor Peng Cui's group at Tsinghua University put it out on 16 September 2026. Its licence is the main thing a business needs to check, since it allows non-commercial use only and is not open source.

What LimiX-2 does

  • Classification: sorts table rows into classes across tables the model has never seen, without task-specific training.
  • Regression: predicts numeric values from table columns.
  • Missing-value imputation: fills gaps in tables from one pretrained checkpoint.
  • Causal attention: the authors say its feature attention can recover a direct causal skeleton, a claim about explanation rather than accuracy.

Clients
