Introduction

This official repo introduces the TransNormerLLM model, featuring its open-source weights. Additionally, it provides codes for Supervised Fine-tuning (SFT) and inference.

TransNormerLLM evolving from TransNormer, standing out as the first LLM within the linear transformer architecture. Additionally, it distinguishes itself by being the first non-Transformer LLM to exceed both traditional Transformer and other efficient Transformer models (such as, RetNet and Mamba) in terms of speed and performance.

• TransNormerLLM1 is released in Nov 2023, featuring three versions with 385M, 1B, and 7B parameters, trained on 1.4 trillion tokens.
• The latest update transitions from TransNormerLLM1 to TransNormerLLM2, offering three updated versions with 1B, 3B, and 7B parameters, trained on 0.3 trillion tokens.
• All versions are available as open-source under the Apache-2.0 license.

Diff of TransNormerLLM2

• TransNormerLLM1 incorporates Simple GLU in its channel mixer, GLA in the token mixer, and SRMSNorm for normalization. In this model, the channel and token mixers function sequentially in a pipeline arrangement.
• TransNormerLLM2 also utilizes Simple GLU in the channel mixer, GLA in the token mixer, and SRMSNorm for normalization. However, in this version, the channel and token mixers operate concurrently, in parallel.

Benchmark Results

TransNormerLLM are evaluated on Commonsense Reasoning tasks and Multiple-Choice questions. For comparison, a range of open-source models are chosen for comparison, encompassing both Transformer-based and non-Transformer-based architectures. The evaluations of all models are conducted using the official settings and the lm-evaluation-harness framework.

Inference and Deployment

Dependency Installation

📝Note Please configure the following environment before using the model:

pip install triton==2.0.0
pip install einops

Notice

If you experience errors associated with Triton, it is advisable to disable Triton.

export use_triton=False

Inference

>>> from transformers import AutoModelForCausalLM, AutoTokenizer
>>> tokenizer = AutoTokenizer.from_pretrained("OpenNLPLab/TransNormerLLM2-3B-300B", trust_remote_code=True)
>>> model = AutoModelForCausalLM.from_pretrained("TransNormerLLM2-3B-300B", device_map="auto", trust_remote_code=True)
>>> inputs = tokenizer('今天是美好的一天', return_tensors='pt')
>>> pred = model.generate(**inputs, max_new_tokens=2048, repetition_penalty=1.0)
>>> print(tokenizer.decode(pred.cpu()[0], skip_special_tokens=True))

• Note: we recommend to use bfloat16 in TransNormerLLM, float16 might lead nan error, please check your divce compatibility!

Fine-tuning the Model

Dependency Installation

git clone https://github.com/OpenNLPLab/TransNormerLLM.git
cd TransNormerLLM/fine-tune
pip install -r requirements.txt

• To use lightweight fine-tuning methods like LoRA, you must additionally install peft.

Training

Below, we provide an example of fine-tuning the TransNormerLLM-1B on a single machine with ZeRO-3.

Training Data: alpaca_data.json. This sample data was drawn from alpaca_data.json, consisting of a selection of 52,002 entries, and has been reformatted. The main purpose is to demonstrate how to SFT our model, and effectiveness is not guaranteed.

We also advise against using these models for online services that haven't passed security reviews and legal procedures. We hope everyone will follow these guidelines to ensure technology develops in a safe and lawful way.

We've tried hard to make sure the data in our model training is compliant, but because the model and data are complex, there might still be unexpected issues. If any problems occur from using TransNormerLLM open-source models, like data security issues, public opinion risks, or problems caused by misuse or improper use of the model, we will not be responsible.
