Notes

Synthetic-only checkpoints of the 2.5 release (those without the real-data mark on the model card). The default classification checkpoint tabpfn-v2.5-classifier-v2.5_default.ckpt is the real-data fine-tuned one (see real-tabpfn-2-5); the default regression checkpoint is synthetic-only per the card: 'default regression checkpoint, trained on synthetic data only.'
