+# Llama3-8B-SuperNova-Spectrum-Hermes-DPO
+This model is a **DPO fine-tuned** version of my `DARE_TIES` merged Model [`yuvraj17/Llama3-8B-SuperNova-Spectrum-dare_ties`](https://huggingface.co/yuvraj17/Llama3-8B-SuperNova-Spectrum-dare_ties) on the [yuvraj17/chatml-OpenHermes2.5-dpo-binarized-alpha-2k](https://huggingface.co/datasets/yuvraj17/chatml-OpenHermes2.5-dpo-binarized-alpha-2k) dataset.
+## DPO (Direct Preference Optimization):
+Direct Preference Optimization (DPO) is a fine-tuning technique that focuses on aligning a model's responses with human preferences or ranking data without requiring reinforcement learning steps, like in RLHF.

+      bias="none",
+      task_type="CAUSAL_LM",
+      target_modules=['k_proj', 'gate_proj', 'v_proj', 'up_proj', 'q_proj', 'o_proj', 'down_proj']
+  )
+  ```
+### Training Params

+## 💻 Usage
+```python
+!pip install -qU transformers accelerate
+from transformers import AutoTokenizer
+import transformers
+import torch
+model = "yuvraj17/Llama3-8B-SuperNova-Spectrum-Hermes-DPO"
+messages = [{"role": "user", "content": "What is a large language model?"}]
+tokenizer = AutoTokenizer.from_pretrained(model)
+prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+pipeline = transformers.pipeline(
+    "text-generation",
+    model=model,
+    torch_dtype=torch.float16,
+    device_map="auto",
+)
+outputs = pipeline(prompt, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)
