About

What FLM-2-2407 is

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

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.

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.).

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys flm-2-2407 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (flm-2-2407 below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/embeddings \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"flm-2-2407","input":"text to embed"}'
