Llama3-PBM-Nova-70B
Introduction
Llama3-PBM-Nova-70B is a chat model developed by PKU-Baichuan-MLSysLab, based on the Llama3-70B. In order to better utilize open-source data, we've performed deduplication, quality filtering, and data synthesis on it. Then, through Supervised Fine-Tuning (SFT) and Reinforcement Learning from Human Feedback (RLHF), we've significantly enhanced the base model's performance.
- Developed by: PKU-Baichuan-MLSysLab
- Base Model: Llama-3-70B

Usage
Below is an example of how to use this model based on the Transformers library.
import transformers
import torch
model_id = "PKU-Baichuan-MLSystemLab/Llama3-PBM-Nova-70B"
pipeline = transformers.pipeline(
"text-generation",
model=model_id,
model_kwargs={"torch_dtype": torch.bfloat16},
device_map="auto",
)
messages = [
{"role": "user", "content": "Who are you?"},
]
terminators = [
pipeline.tokenizer.eos_token_id,
pipeline.tokenizer.convert_tokens_to_ids("<|eot_id|>")
]
outputs = pipeline(
messages,
max_new_tokens=256,
eos_token_id=terminators,
do_sample=True,
temperature=0.6,
top_p=0.9,
)
print(outputs[0]["generated_text"][-1])
