 Tulu is a series of language models that are trained to act as helpful assistants.
 Tulu V2.5 is a series of models trained using DPO and PPO starting from the [Tulu 2 suite](https://huggingface.co/collections/allenai/tulu-v2-suite-6551b56e743e6349aab45101).
-This model is trained on the UltraFeedback dataset (using the per-aspect/fine-grained scores for deciding chosen and rejected) using PPO.
+This model is trained using PPO.
 We used a 70B RM trained on our preference data mix, and then used the UltraFeedback prompts during PPO training.
