Introduction

FLM-2 (aka Tele-FLM) is our open-source large language model series. The FLM-2 series demonstrate superior performances at its scale, and sometimes surpass larger models. The currently released versions include (Tele-FLM)[https://huggingface.co/CofeAI/Tele-FLM] and (Tele-FLM-1T)[https://huggingface.co/CofeAI/Tele-FLM-1T]. These models feature a stable, efficient pre-training paradigm and enhanced factual judgment capabilities. This repo contains the instruction-tuned 52B Tele-FLM model, which we have named FLM-2-52B-Instruct.

Model Details

FLM-2-52B-Instruct utilizes the standard GPT-style decoder-only transformer architecture with a few adjustments:

Rotary Positional Embedding (RoPE)
RMSNorm for normalization
SwiGLU for activation function
Linear bias disabled
Embedding and language model head untied
Input and output multiplier

Models	layer number	attention heads	hidden size	ffn hidden size	vocab size	params count
FLM-2-52B-Instruct-2407	64	64	8,192	21,824	80,000	52.85 B

Training details

Unlike conventional fine-tuning methods, we employed an innovative and cost-effective fine-tuning approach. Through specialized screening techniques, we meticulously selected 30,735 samples from a large corpus of fine-tuning data. This refined dataset facilitated the fine-tuning process and yielded promising results.

Quickstart

Here provides simple code for loading the tokenizer, loading the model, and generating contents.

python

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained('CofeAI/FLM-2-52B-Instruct-2407', trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained('CofeAI/FLM-2-52B-Instruct-2407', torch_dtype=torch.bfloat16, low_cpu_mem_usage=True, device_map="auto", trust_remote_code=True)
history = [
    {"role": "user", "content": "你好"},
    {"role": "assistant", "content": "你好"},
    {"role": "user", "content": "北京有哪些必去的景点？"}
]
inputs = tokenizer.apply_chat_template(history, return_tensors='pt').to(model.device)
response = model.generate(inputs, max_new_tokens=128, repetition_penalty=1.03)
print(tokenizer.decode(response.cpu()[0], skip_special_tokens=True))

Evaluation

We evaluate the alignment performance of FLM-2-52B-Instruct-2407 in Chinese across various domains utilizing AlignBench. AlignBench is a comprehensive and multidimensional evaluation benchmark designed to assess Chinese large language models’ alignment performance. It encompasses 8 categories with a total of 683 question-answer pairs, covering areas such as fundamental language ability (Fund.), Chinese advanced understanding (Chi.), open-ended questions (Open.), writing ability (Writ.), logical reasoning (Logi.), mathematics (Math.), task-oriented role playing (Role.), and professional knowledge (Pro.).
