Training

Fit a Model

Deprecated: Prefer the TabPFN client (tabpfn-client) or POST /tabpfn/fit after preparing uploads. This multipart /v1/fit surface is legacy. See the TabPFN-3 changelog.

Uploads and fits a TabPFN model on your training data. The API automatically handles preprocessing and stores a reference to your trained context (not the model weights). You can use either a single dataset file (with the target column included) or separate feature and label files.
