+# Zephyr 7B SFT aligned with DPO on HH-RLHF with β=0.01
+
+This repo contains LoRA adapter created by aligning [Zephyr 7B SFT](https://huggingface.co/alignment-handbook/zephyr-7b-sft-full) on the [Anthropic HH-RLHF](https://huggingface.co/datasets/Anthropic/hh-rlhf) dataset using Direct Preference Optimization (DPO).
+It was trained as a series of models for studying DPO alignment.
+
+## Model details
+
+* Base model: [alignment-handbook/zephyr-7b-sft-full](https://huggingface.co/alignment-handbook/zephyr-7b-sft-full)
+* Preference dataset: [Anthropic/hh-rlhf](https://huggingface.co/datasets/Anthropic/hh-rlhf)
+* DPO beta: 0.01
+* Training framework: PEFT/LoRA
+
+See the base model card for usage and chat template details.
+
+## Training hyperparameters
+
+* Epochs: 1
+* Batch size: 16
+* Learning rate: 5e-06
+* Learning rate scheduler: cosine
+* Learning rate warmup ratio: 0.1
+* Gradient accumulation: 2
+* LoRA:
+  * rank: 64
+  * alpha: 64
+  * dropout: 0.05
+  * target modules: [q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj]
