Model Card for LION-LLaMA-3-8b-dpo-v1.0
The LION-series are trained using an empirically optimized pipeline that consists of three stages: SFT, DPO, and online preference learning (online DPO). We find simple techniques such as sequence packing, loss masking in SFT, increasing the preference dataset size in DPO, and online DPO training can significantly improve the performance of language models. Our best models (the LION-series) exceed the performance of the official instruct models tuned with closed-source data and algorithms.
For training datasets, code, and evaluation scripts, please refer to our paper and codebase.

Intended uses
To ensure reproducibility, please use the following chat templates:
import torch
from transformers import pipeline
pipe = pipeline(
"text-generation",
model="Columbia-NLP/LION-LLaMA-3-8b-dpo-v1.0",
device_map="auto",
torch_dtype=torch.bfloat16,
)
messages = [
# no system message for LLaMa
{
"role": "user",
"content": "Write a short paragraph where every sentence starts with the letter A."
},
]
outputs = pipe(
messages,
max_new_tokens=128,
do_sample=False,
stop_sequence="<|im_end|>",
)
print(outputs[0]["generated_text"][-1]["content"])
# Astonishingly, all animals adore appealing, aromatic apples.
# An array of apples always attracts adventurous ants.
# After analyzing, ants ascertain the apple's accessibility.
# Anticipation amplifies as they approach, anticipating an appetizing treat.
to inspect the chat template/manually do generation:
tokenizer = AutoTokenizer.from_pretrained("Columbia-NLP/LION-LLaMA-3-8b-dpo-v1.0")
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
print(prompt)
# tokenize prompt and use model.generate
