 Zamba2-2.7B-Instruct is obtained from [Zamba2-2.7B](https://huggingface.co/Zyphra/Zamba2-2.7B) by fine-tuning on instruction-following and chat datasets. Specifically:
 
-1. SFT of the base [Zamba2-2.7B](https://huggingface.co/Zyphra/Zamba2-2.7B) model on [ultrachat_200k](HuggingFaceH4/ultrachat_200k) and [Infinity-Instruct](https://huggingface.co/datasets/BAAI/Infinity-Instruct)

 2. DPO of the SFT checkpoint on [ultrafeedback_binarized](https://huggingface.co/datasets/HuggingFaceH4/ultrafeedback_binarized), [orca_dpo_pairs](https://huggingface.co/datasets/Intel/orca_dpo_pairs), and [OpenHermesPreferences](https://huggingface.co/datasets/argilla/OpenHermesPreferences)
 
 Zamba2-2.7B-Instruct is a hybrid model composed of state-space ([Mamba2](https://github.com/state-spaces/mamba)) and transformer blocks.
