Mistral-ORPO-β (7B)

Mistral-ORPO is a fine-tuned version of mistralai/Mistral-7B-v0.1 using the odds ratio preference optimization (ORPO). With ORPO, the model directly learns the preference without the supervised fine-tuning warmup phase. Mistral-ORPO-β is fine-tuned exclusively on the 61k instances of the cleaned version of UltraFeedback, argilla/ultrafeedback-binarized-preferences-cleaned, by Argilla.
