Vikarti notes

GGUF versions of https://huggingface.co/wenbopan/Faro-Yi-9B-DPO

Thanks to https://new.reddit.com/user/Downtown-Case-1755/ for making it known in https://new.reddit.com/r/LocalLLaMA/comments/1cziy0m/what_is_sota_for_a_mega_context_100k_novel/ that long-context models could be used by GPU-poor people who doesn't have 3090/4090.

Faro-Yi-9B-DPO

This is the DPO version of wenbopan/Faro-Yi-9B. Compared to Faro-Yi-9B and Yi-9B-200K, the DPO model excels at many tasks, surpassing the original Yi-9B-200K by a large margin. On the Open LLM Leaderboard, it ranks #2 among all 9B models, #1 among all Yi-9B variants.

Faro-Yi-9B-DPO's responses are also favored by GPT-4 Judge in MT-Bench

How to Use

Faro-Yi-9B-DPO uses the chatml template and performs well in both short and long contexts. For longer inputs under 24GB of VRAM, I recommend to use vLLM to have a max prompt of 32K. Setting kv_cache_dtype="fp8_e5m2" allows for 48K input length. 4bit-AWQ quantization on top of that can boost input length to 160K, albeit with some performance impact. Adjust max_model_len arg in vLLM or config.json to avoid OOM.

from PyPDF2 import PdfReader
from vllm import LLM, SamplingParams

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)
