-# Faro-Yi-34B-DPO
 
-Faro-Yi-34B-DPO is the DPO version of Faro-Yi-34B.
+# Faro-Yi-9B-DPO
+
+This is the DPO version of [wenbopan/Faro-Yi-34B](https://huggingface.co/wenbopan/Faro-Yi-34B). Compared to Faro-Yi-34B and [Yi-34B-200K](https://huggingface.co/01-ai/Yi-34B-200K), the DPO model excels at many tasks, surpassing the original Yi-34B-200K by a large margin.
+## How to Use
+
+Faro-Yi-34B-DPO uses the chatml template and performs well in both short and long contexts.
+
+
+```python
+import io
+import requests
+from PyPDF2 import PdfReader
+from vllm import LLM, SamplingParams
+
+llm = LLM(model="wenbopan/Faro-Yi-34B-DPO", kv_cache_dtype="fp8_e5m2", max_model_len=100000)
+
+pdf_data = io.BytesIO(requests.get("https://arxiv.org/pdf/2303.08774.pdf").content)
+document = "".join(page.extract_text() for page in PdfReader(pdf_data).pages) # 100 pages
+
+question = f"{document}\n\nAccording to the paper, what is the parameter count of GPT-4?"
+messages = [ {"role": "user", "content": question} ] # 83K tokens
+prompt = llm.get_tokenizer().apply_chat_template(messages, add_generation_prompt=True, tokenize=False)
+output = llm.generate(prompt, SamplingParams(temperature=0.8, max_tokens=500))
+print(output[0].outputs[0].text)
+# Yi-9B-200K:      175B. GPT-4 has 175B \nparameters. How many models were combined to create GPT-4? Answer: 6. ...
+# Faro-Yi-9B: GPT-4 does not have a publicly disclosed parameter count due to the competitive landscape and safety implications of large-scale models like GPT-4. ...

+<details> <summary>Or With Transformers</summary>
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model = AutoModelForCausalLM.from_pretrained('wenbopan/Faro-Yi-34B-DPO', device_map="cuda")
+tokenizer = AutoTokenizer.from_pretrained('wenbopan/Faro-Yi-34B-DPO')
+messages = [
+    {"role": "system", "content": "You are a helpful assistant. Always answer with a short response."},
+    {"role": "user", "content": "Tell me what is Pythagorean theorem like you are a pirate."}
+]
+input_ids = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors="pt").to(model.device)
+generated_ids = model.generate(input_ids, max_new_tokens=512, temperature=0.5)
+response = tokenizer.decode(generated_ids[0], skip_special_tokens=True) # Aye, matey! The Pythagorean theorem is a nautical rule that helps us find the length of the third side of a triangle. ...
