Model Introduction

Llama-3-SynE (<ins>Syn</ins>thetic data <ins>E</ins>nhanced Llama-3) is a significantly enhanced version of Llama-3 (8B), achieved through continual pre-training (CPT) to improve its Chinese language ability and scientific reasoning capability. By employing a meticulously designed data mixture and curriculum strategy, Llama-3-SynE successfully enhances new abilities while maintaining the original model’s performance. This enhancement process involves utilizing existing datasets and synthesizing high-quality datasets specifically designed for targeted tasks.

Key features of Llama-3-SynE include:

Enhanced Chinese Language Capabilities: Achieved through topic-based data mixture and perplexity-based data curriculum.
Improved Scientific Reasoning: Utilizing synthetic datasets to enhance multi-disciplinary scientific knowledge.
Efficient CPT: Only consuming around 100 billion tokens, making it a cost-effective solution.

BenchMark

We divide all evaluation benchmarks into two groups. The first group is major benchmarks, which aim to evaluate the comprehensive capacities of LLMs. Note that we include commonly used math and code benchmarks in this group because it is standard practice to use these benchmarks for evaluating various general-purpose LLMs.

The second group is scientific benchmarks, which have a broader coverage of multidisciplinary scientific knowledge.

We report the eight-shot performance on GSM8K, ASDiv, and MAWPS, five-shot for C-Eval, CMMLU, MMLU, MATH, GaoKao, SciQ, SciEval, SAT-Math, and AQUA-RAT, three-shot for MBPP. For HumanEval and ARC, we report the zero-shot evaluation performance. The best and second best are in bold and <ins>underlined</ins>, respectively.

On Chinese evaluation benchmarks (such as C-Eval and CMMLU), Llama-3-SynE significantly outperforms the base model Llama-3 (8B), indicating that our method is very effective in improving Chinese language capabilities.

On English evaluation benchmarks (such as MMLU, MATH, and code evaluation benchmarks), Llama-3-SynE demonstrates comparable or better performance than the base model, indicating that our method effectively addresses the issue of catastrophic forgetting during the CPT process.

Quick Start

Use the transformers backend for inference:

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_path = "survivi/Llama-3-SynE"
tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_path, torch_dtype=torch.bfloat16, trust_remote_code=True
)
model.to("cuda:0")
model.eval()
prompt = "Hello world!"
inputs = tokenizer(prompt, return_tensors="pt")
inputs = inputs.to("cuda")
pred = model.generate(
    **inputs,
    max_new_tokens=2048,
    repetition_penalty=1.05,
    temperature=0.5,
    top_k=5,
    top_p=0.85,
    do_sample=True
)
pred = pred[0][len(inputs.input_ids[0]) :]
output = tokenizer.decode(pred, skip_special_tokens=True)
print(output)

Use the vLLM backend for inference:

from transformers import AutoTokenizer
from vllm import LLM, SamplingParams

model_path = "survivi/Llama-3-SynE"
tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True)
sampling_params = SamplingParams(
    max_tokens=2048,
    repetition_penalty=1.05,
    temperature=0.5,
    top_k=5,
    top_p=0.85,
)
llm = LLM(
    model=model_path,
    tensor_parallel_size=1,
    trust_remote_code=True,
)
prompt = "Hello world!"
output = llm.generate(prompt, sampling_params)
output = output[0].outputs[0].text
print(output)
