AMALIA DPO Dataset

This is the DPO (preference optimization) dataset used to train AMALIA-DPO. It is a mix of preference pairs, mainly in European Portuguese and English, covering general conversation, instruction following, math, and safety. These pairs come from different sources, including prompts from the SFT mix, responses generated by different models, including an early version of the model, and some public datasets.

This dataset is provided as part of the AMALIA project and is included in the data mix used to post-train the AMALIA model.
