🔥🆕🆕🔥 Dataset Drop: 4 KTO signal transformed versions of the highly loved Argilla DPO datasets.
KTO formats for:
- UltraFeedback Cleaned Binarized
- Distilabel Intel Orca
- Distilabel Capybara
- DPO mix

KTO matches or exceeds DPO performance at scales from 1B to 30B parameters.1 That is, taking a preference dataset of n DPO pairs and breaking it up into 2n examples for KTO can yield better generations, despite the model ostensibly learning from a weaker signal.
KTO can handle extreme data imbalances, matching DPO performance while using up to 90% fewer desirable examples (i.e., examples of good generations). Its success thus cannot be ascribed to the alignment data being sourced from a preference dataset.
When the pretrained model is sufficiently good, one can skip supervised finetuning and go straight to KTO without a loss in generation quality. In contrast, we find that without doing SFT first, DPO-aligned models are significantly worse at all scales.
Do you need something custom? Take a look at @davanstrien his guide on creating your own KTO dataset with Argilla and our community.
