Fine-tuning ChatGLM4 for Large Model Instruction Following (with Code and Test Scripts)
Author: Emotional Machine Lab - Chen Shaohong
Email: shaohon_chen@115lab.club
Abstract
This tutorial primarily implements a fine-tuning method for large model instruction following. To simplify implementation and reduce code complexity, this article uses the 🤗HuggingFace TRL framework. In addition to supporting SFT, this framework provides excellent support for popular reinforcement fine-tuning algorithms such as DPO, PPO, and GRPO.
While using frameworks can significantly reduce workload, it inevitably poses challenges for beginners. Therefore, this tutorial will include comprehensive documentation references to help readers further understand the framework. Although implementing the fine-tuning process from scratch with PyTorch can greatly enhance understanding, and there are many excellent community projects available, the author still recommends using frameworks for training. This approach saves substantial time, allowing users to focus more on innovation.
Thus, this tutorial is recommended for readers with some familiarity with the 🤗HuggingFace Transformers framework.
Note: Due to the relatively large size of the ChatGLM model, actual execution requires approximately >=16GB of GPU memory.
🎉 SwanLab has been officially integrated into 🤗HuggingFace Transformers: If SwanLab is installed locally, it will be enabled by default! It can also be activated via report_to="swanlab" for training tracking.

TRL Package Introduction + Environment Setup
This tutorial uses the 🤗HuggingFace TRL framework to implement the fine-tuning code. TRL is a powerful and user-friendly fine-tuning framework that not only supports SFT but also easily integrates popular reinforcement fine-tuning algorithms like DPO, PPO, and GRPO through its interfaces. Additionally, it is fully compatible with the Transformers architecture.
First, set up the environment for this tutorial with the following installation command:
pip install transformers trl datasets peft swanlabHere, transformers, trl, and peft are used for model loading and training, datasets for importing datasets, and swanlab for visualizing and tracking the training process.
Below is a simple fine-tuning example to introduce the usage of the HF TRL framework:
from datasets import load_dataset
from trl import SFTConfig, SFTTrainer
dataset = load_dataset("stanfordnlp/imdb", split="train") # Set the fine-tuning dataset; here, IMDB movie review classification data is used
training_args = SFTConfig( # Set fine-tuning parameters
max_length=512,
output_dir="/tmp",
)
trainer = SFTTrainer( # Set the model; here, Facebook's opt-350M is used, which has a small parameter count for easy downloading
"facebook/opt-350m",
train_dataset=dataset,
args=training_args,
)
trainer.train() # Start training; the process is similar to TRLThe above code is from the HF official documentation https://huggingface.co/docs/trl/sft_trainer, with added comments for better understanding.
In short, the TRL package is used similarly to Transformers, but with two additional steps:
• Import the SFTConfig module, which is based on transformers' TrainingArguments but introduces some extra parameters for SFT and LoRA support.
• Import the SFTTrainer module, which includes the SFT implementation code and some additional support for peft's LoRA and dataset format conversion.
The following sections will provide a complete guide on using the TRL package to achieve large model instruction following.
ChatGLM4 Introduction + Model Preparation
GLM-4-9B is the latest open-source version of the GLM-4 series of pre-trained models released by Zhipu AI. ChatGLM has released multiple versions, with GLM-4-9B being the fourth-generation base model. Its fine-tuned version, GLM-4-9B-Chat, includes advanced features such as web browsing, code execution, custom tool invocation (Function Call), and long-context reasoning (supporting up to 128K tokens).
This tutorial uses the GLM-4-9B model for instruction following fine-tuning and employs SwanLab for model performance tracking.
⚠️ Note: To align with HuggingFace Transformers updates, ChatGLM has released two versions of weights: THUDM/glm-4-9b and THUDM/glm-4-9b-hf. The latter corresponds to newer versions of transformers, so this tutorial uses the latter.
This tutorial provides a script to download the model. The download method is as follows:
huggingface-cli download --local-dir ./weights/glm-4-9b-hf THUDM/glm-4-9b-hfThe model will be downloaded to ./weights/glm-4-9b-hf in the project directory.
Below is an example of loading the ChatGLM model using transformers and performing inference:
from transformers import AutoTokenizer, AutoModelForCausalLM
device = "cuda"
tokenizer = AutoTokenizer.from_pretrained("THUDM/glm-4-9b-chat-hf")
model = AutoModelForCausalLM.from_pretrained("THUDM/glm-4-9b-chat-hf").eval().to(device)
inputs = tokenizer.encode("我是ChatGLM，是", return_tensors="pt").to(device)
outputs = model.generate(inputs)
print(tokenizer.decode(outputs[0]))Since this is a base model without fine-tuning, it will only complete the text following "我是ChatGLM，是". Running this will generate the following output:
Loading checkpoint shards: 100%|██████████| 4/4 [00:01<00:00, 2.35it/s]
[gMASK]<sop>我是ChatGLM，是人工智能助手。我是ChatGLM，是人工智能助手。我是ChatGLM，是人工智能助手The above example demonstrates inference with a base model, which can only perform text generation. To enable conversational capabilities, the fine-tuned chat model must be loaded, as shown below:
from transformers import pipeline
messages = [
{"role": "user", "content": "你是谁"},
]
pipe = pipeline("text-generation", model="THUDM/glm-4-9b-chat-hf")
print(pipe(messages))Here, we use the pipeline interface for inference. Running this will generate the following output:
Loading checkpoint shards: 100%|██████████| 4/4 [00:01<00:00, 2.24it/s]
Device set to use cuda:0
[{'generated_text': [{'role': 'user', 'content': '你是谁'}, {'role': 'assistant', 'content': '\n我是一个人工智能助手，名为 ChatGLM。我是基于清华大学 KEG 实验室和'}]}]Printing the model structure with print(model) reveals the following:
GlmForCausalLM(
(model): GlmModel(
(embed_tokens): Embedding(151552, 4096, padding_idx=151329)
(layers): ModuleList(
(0-39): 40 x GlmDecoderLayer(
(self_attn): GlmAttention(
(q_proj): Linear(in_features=4096, out_features=4096, bias=True)

(down_proj): Linear(in_features=13696, out_features=4096, bias=False)
(activation_fn): SiLU()
)
(input_layernorm): GlmRMSNorm((4096,), eps=1.5625e-07)
(post_attention_layernorm): GlmRMSNorm((4096,), eps=1.5625e-07)
)
)
(norm): GlmRMSNorm((4096,), eps=1.5625e-07)
(rotary_emb): GlmRotaryEmbedding()
)
(lm_head): Linear(in_features=4096, out_features=151552, bias=False)
)The GLM model has an impressive 40 layers 😂, so when using LoRA for fine-tuning, the number of trainable parameters will be larger compared to other models.
Dataset Preparation
The dataset has already been included in the GitHub project and can be downloaded directly using the following command to obtain the complete experimental code:
git clone https://github.com/SwanHubX/glm4-finetune.gitIf you only want to download the dataset, you can directly download the following file:
wget https://github.com/SwanHubX/glm4-finetune/blob/main/data/alpaca_gpt4_data_zh.jsonAlternatively, it can be downloaded from 🤗HuggingFace: https://huggingface.co/datasets/llamafactory/alpaca_gpt4_zh
Code Explanation + Hyperparameter Tuning
The complete fine-tuning code is publicly available on GitHub. You can download it using the following command:
git clone https://github.com/SwanHubX/glm4-finetune.gitThe article's attachments also include the full implementation code [#Code Attachment](#Attachment: Full Code).
This article will now focus on explaining the functional modules of the code.
Model Loading and Hyperparameter Settings
Here, special attention should be paid to the LoRA parameter settings. The LoRA parameters in this article are based on the official ChatGLM fine-tuning code.
Note that the learning rate is set to 5e-4. For full fine-tuning, it should be reduced by an order of magnitude.

}Here, readers might wonder why there are both instruction and input sections. Early research on instruction-following aimed to create a general-purpose task-processing model (e.g., capable of both translation and calculations). Thus, task descriptions were placed in instruction, while the actual task text was placed in input.
However, with the advent of general-purpose AI assistants like ChatGPT, users have grown accustomed to directly issuing instructions. As a result, separating instruction and prompt has become less necessary. Fundamentally, whether separated or not, the model's core function remains predicting subsequent text based on context. The separation only affects the format, not the final outcome.
Modern open-source chat-based large language models (LLMs) often place "persona" in the system prompt and user instructions in input. Therefore, we will later reformat the Alpaca dataset to align with mainstream chat model conventions.
The recommended input fine-tuning data structure provided by ChatGLM is as follows:
{
"messages": [
{
"role": "user",
"content": "类型#裤*材质#牛仔布*风格#性感"
},
{
"role": "assistant",
"content": "3x1的这款牛仔裤采用浅白的牛仔面料为裤身材质，其柔然的手感和细腻的质地，在穿着舒适的同时，透露着清纯甜美的个性气质。除此之外，流畅的裤身剪裁将性感的腿部曲线彰显的淋漓尽致，不失为一款随性出街的必备单品。"
}
]
}Experienced readers might argue that since we are training from scratch, we can define our own data structure. While this is true, to leverage ChatGLM's native chat_template, we recommend adhering to the official data format. This ensures compatibility with ChatGLM's tools and full utilization of its special tokens.
The native chat_template can be found in the tokenizer_config.json of the open-source glm-4-9b-chat-hf on HuggingFace. The following script prints the chat_template:
from transformers import AutoTokenizer, AutoModelForCausalLM
device = "cuda"
tokenizer = AutoTokenizer.from_pretrained("THUDM/glm-4-9b-chat-hf")
print(tokenizer.chat_template)Link to the tokenizer configuration:
https://huggingface.co/THUDM/glm-4-9b-chat-hf/blob/main/tokenizer_config.json
Below is a simple demonstration of the final dataset format after conversion:
def formatting_func(example):
"""
process data format
"""
prompt = example["instruction"]
if len(example["input"]) != 0:
prompt += "\n\n" + example["input"]
conversations = [
{"role": "user", "content": prompt},
{"role": "assistant", "content": example["output"]},
]
output_text = tokenizer.apply_chat_template(
conversation=conversations, tokenize=False
)
return output_textOutput example (this is the actual data format fed to the model during fine-tuning):

Multi-GPU Training
If you have multiple GPUs, we recommend using multi-GPU training to significantly speed up training! First, install HuggingFace accelerate and deepspeed to easily enable Zero2 multi-GPU training:
pip install accelerate deepspeedThen, use the following command to start multi-GPU training (default: 8 GPUs; adjust num_processes as needed):
accelerate launch --num_processes 8 --config_file configs/zero2.yaml train.pyDetailed Zero2 settings are in configs/zero2.yaml.
The model will be saved in output/lora-glm4-9b-alpaca. Due to limited disk space, only LoRA weights are saved. Remember to load the original model during inference.
Inference + Performance Comparison
Use the following command for command-line chat:
