TabFM is a zero-shot tabular foundation model from Google Research. It supports classification and regression on structured/tabular data with mixed numerical and categorical columns, requiring no fine-tuning or hyperparameter search - training examples are passed as context and predictions are made in a single forward pass.

This repository contains the **PyTorch** weights. For the JAX/Flax weights see [google/tabfm-1.0.0-jax](https://huggingface.co/google/tabfm-1.0.0-jax).

## Getting Started

```
pip install tabfm[pytorch]
```

**Classification:**

```
from tabfm import TabFMClassifier, tabfm_v1_0_0_pytorch as tabfm_v1_0_0

model = tabfm_v1_0_0.load(model_type="classification")
clf = TabFMClassifier(model=model)
clf.fit(X_train, y_train)
probs = clf.predict_proba(X_test)
```

**Regression:**

```
from tabfm import TabFMRegressor, tabfm_v1_0_0_pytorch as tabfm_v1_0_0

model = tabfm_v1_0_0.load(model_type="regression")
reg = TabFMRegressor(model=model)
reg.fit(X_train, y_train)
preds = reg.predict(X_test)
```

You can also load directly using the HuggingFace Hub API:

```
from tabfm.src.pytorch.tabfm_v1_0_0 import TabFM_HF

clf_model = TabFM_HF.from_pretrained("google/tabfm-1.0.0-pytorch", subfolder="classification")
reg_model = TabFM_HF.from_pretrained("google/tabfm-1.0.0-pytorch", subfolder="regression")
```

### Available Checkpoints

| Subfolder | Task | is\_classifier |
| --- | --- | --- |
| classification/ | Classification (up to 10 classes) | True |
| regression/ | Regression | False |

## Developers and Affiliations

Developed by the [Google Research](https://research.google) team.

## Intended Use

-   Tabular data with numerical and/or categorical columns
-   Binary and multiclass classification (up to 10 classes)
-   Regression on continuous targets
-   Zero-shot inference: no dataset-specific training or hyperparameter tuning
-   Works with DataFrames (pandas) or numpy arrays

## Not Intended For

-   Images, audio, video, or raw text
-   More than 10 output classes (hard model limit)
-   Tasks requiring task-specific fine-tuning
-   Non-tabular structured data (graphs, sequences)
-   Commercial use (see License below)

## Model Architecture

TabFM uses alternating row and column attention to capture both feature interactions and row-level patterns:

1.  **Column attention** (Set Transformer): embeds each cell using Fourier features and a per-group linear projection, then aggregates across rows via induced self-attention
2.  **Row compression**: CLS tokens summarise each row into a dense vector via row-level attention with Rotary Position Embedding (RoPE)
3.  **ICL Transformer**: a 24-block causal transformer operates over the compressed row vectors, treating training rows as context and outputting predictions for test rows

Key hyperparameters:

| Parameter | Value |
| --- | --- |
| Embedding dim | 256 |
| Column attention blocks | 3 (4 heads, 256 induced points) |
| Row attention blocks | 3 (8 heads, 8 CLS tokens) |
| ICL transformer blocks | 24 (8 heads) |
| Feed-forward factor | 4 |
| Max classes | 10 |
| Activation | SwiGLU |
| Fourier features | 32 frequencies |

## Training Data and Priors

TabFM was trained on hundreds of millions of **synthetic** datasets generated dynamically using structural causal models (SCMs). Synthetic data was chosen due to the scarcity of diverse, high-quality open-source tabular datasets and to avoid privacy/licensing concerns with real-world industrial data. The SCM prior encodes inductive biases about causal structure and feature relationships typical in tabular tasks.

## Performance

TabFM was evaluated on [TabArena](https://tabarena.ai) across 51 datasets (38 classification, 13 regression). In zero-shot mode - a single forward pass with no hyperparameter search - TabFM outperforms heavily-tuned supervised baselines including gradient-boosted trees. The `TabFMClassifier.ensemble()` preset (feature crosses, SVD features, NNLS blending) yields further improvements.

See the [Google Research blog post](https://research.google/blog/introducing-tabfm-a-zero-shot-foundation-model-for-tabular-data/) for full benchmark details.

## Ethical Considerations

TabFM was trained entirely on synthetic data. Performance on specific real-world domains, minority groups, or edge distributions is not fully characterised. Users should evaluate the model on held-out data representative of their use case before deploying in high-stakes settings.

## Limitations

-   **Max 10 classes** for classification (hard architectural limit)
-   Memory usage scales with the number of training rows (all rows are passed as context)
-   Optimised for tables up to 500 features; behaviour on very wide tables may degrade
-   Performance is not guaranteed to match task-specific, fine-tuned models on all datasets
-   Not an officially supported Google product
