+## Differences from the paper
+
+> 📢 Attention: The released versions of `cerbero-7b` slightly differ from those used in the paper. The training dataset for the released models was generated using `garage-bAInd/Platypus2-70B-instruct` instead of `meta-llama/Llama-2-7b-chat-hf`, due to the more permissive license of the Platypus2 model (CC-BY-NC 4.0). Our tests indicate that both models produce datasets of comparable quality, and the resulting fine-tuned models demonstrate nearly indistinguishable performance.
