Unveiling the Potential of Gemma as Open Source LLM
This works was collaboration between Joan Santoso (ML GDE), Patrick Sutanto (TFUG Surabaya Core Team), Billy Kelvianto Cahyadi (TFUG Surabaya Core Team).
What is LLM ?
Language models are a type of artificial intelligence (AI) that are trained on a massive amount of text data. This data allows them to learn the statistical patterns of language and how words are used together. This knowledge can then be used to generate human-quality text, translate languages, and even write different kinds of creative content. Most common applications are text generation, summarization and Q&A. The simple way to look at the LLM Capabilities is how the model can complete the missing text.
The model not only can complete analogies, but also has some world knowledge that it’s learned from its training data. (with the caveat that not all knowledge is factually accurate). In all of these cases the LLM predicting what is most likely to come next by look at the frequency distribution of languages. Basically, this is the world’s most sophisticated auto-complete.
LLM can be used on several task based on the instruction that provided to the LLM. This instruction is what we called prompt. This example shows how we made LLM to understand and make an explanation of some jokes that is give by the user. Another example LLM can give a suggestion to user based on their knowledge. For example, we can ask LLM to give a suggestion an interesting idea about some science fair project.
Due popularity of LLM, many researches has been done in developing LLM including the releases of open models. Google also release their latest LLM, that is Gemini on December 2023 and Gemma as their latest Open LLM on February 2024.
Google has a long history on contributing an open model and ecosystem. Start from 2013 Google released Word2Vec, and in 2017 Google also released a Transformer models that widely known as the state-of-the-arts model until now, In the February 2024, Google release Gemma as one of state-of-the-arts open models that we will be discussed today.
What is Gemma ?
Gemma was a lightweight open models that developed using similar architectures, and training recipes as the Gemini Model Family. Gemma released in two size of parameters, i.e., 2B and 7B parameters. Each model has a context length about 8K token and have two type of model, which are base model and instruction tuned versions. The 7B models is mainly used in the development for CPU or GPU environment, meanwhile the 2B version is for the development on CPU or Device applications.
Gemma model architecture is based on the transformer decoder. Models are trained on a context length of 8192 tokens. Multi-Head Attention in 7B Model and Multi-Query Attention in 2 B Model. Rather than using absolute positional embeddings, Gemma use Rotary Positional Embedding (Su et al., 2021) Share embeddings across our inputs and outputs to reduce model size and standard ReLU replaced by GeGLU Activations. Each Transformer Sub-Layer, attention layer, and Feed-forward layer was normalize using RMSNorm.
Benefit of Gemma Open Source Model
There are some benefit of Gemma as Open Source Language Models:
- Lower barriers to entry for developers and researchers.
2. Foster collaboration and innovation in the AI community.
3. Open code allows other user to examine and contribute to make it better.
4. Builds trust in the development and application of AI.
5. Developers can tailor Gemma to specific needs and applications.
6. Promotes innovation and exploration of new functionalities.
Comparing Gemma to others has been done in a lot of different areas, both automatically and by people. In addition, it shows that Gemma does well on math and code tests. Beat even bigger models on important standards, getting great results without needing a lot of resources. We can use it in our creation since it can be run on a local device and works best on laptops, desktops, and mobile computing.
Google filters the pre-training dataset to lower the chance of hearing unwanted or harmful speech. They also remove some personal information and other private data. This includes getting rid of harmful or low-quality material with both heuristics and model-based classifiers. Google believes that both steps are necessary for better results in automatic evaluations further down the line and evaluations of model outputs by humans.
Google has recently launched a Generative AI Responsible Toolkit to assist developers in constructing AI systems in a responsible manner. This includes a range of resources to assist developers in designing and implementing responsible AI best practices and ensuring the safety of their users. For more details look at in here.
Gemma can be run in multiple library such as Keras, PyTorch, JAX, or even HuggingFace. Surprisingly we can run Gemma on laptop, desktop, or mobile devices to use it in our development. Google also partner with NVIDIA to optimize Gemma in variety of NVIDIA Hardware from the data centers into your local pc. And also to provide a seamless integration with Google Cloud infrastructure. We can use Vertex AI to deploy Gemma and do some customization and optimization.
Gemma Case Study
Now let’s move to the example cases of Gemma. We have 3 cases for demonstrate the Gemma Capabilities:
A. Instruction Prompt in Gemma.
In this first case example, we create a instruction prompt using Gemma. In this example, we create a QA system using prompt that provided to the Gemma. For this experiment, we use Gemma 7B-it version and several library such as HuggingFace, BitsandBytes, and Accelerate. For the first time, we need to install our library by using this runing this several line of codes.
pip install bitsandbytes --upgrade
pip install accelerate
pip install git+https://github.com/huggingface/peft@27af2198225cbb9e049f548440f2bd0fba2204aaAfter that let’s import several library that we needs to run the models by add some codes as follows.
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig
import accelerateTo access the Gemma models, we need a HuggingFace tokens. We can input the access tokens that we get into our program.
access_token = 'add your huggingface token here'Now it’s time for download or load the model if you already download it. We use BitsandBytes to quantize it into 4bit. We can use some code as follows.
quantization_config = BitsAndBytesConfig(load_in_4bit=True)
tokenizer = AutoTokenizer.from_pretrained("google/gemma-7b-it", token=access_token)
model = AutoModelForCausalLM.from_pretrained("google/gemma-7b-it", quantization_config=quantization_config, token=access_token)Now let’s create the prompt example as follows. We use several cases for creating a QA system about my university, that is Institut Sains dan Teknologi Terpadu Surabaya.
'''
f = open("prompt.txt", "r")
template = f.read()
'''
template = '''

'''We add two parts in this example. The first one is the instruction and the second one is the context of the prompts. We also add some example to the Gemma on how to answer the several questions that provided as an example.
To maintain the context of the discussion, we create a list of answer and questions to capture the history of the conversation. This list will be included to the prompt that will be fed into Gemma. We create a function that will help to generate the input to the Gemma.
def generate_input(template, list_of_inputs, list_of_answers):
end = 5 if len(list_of_inputs) >=5 else len(list_of_inputs)
input_string = template
for i in range(end, 0, -1):
#print(i)
input_string = input_string+"\n"+f"User: {list_of_inputs[len(list_of_inputs)-i]}\n"
if len(list_of_inputs)-i < len(list_of_answers):
input_string = input_string+f"TalonTech: {list_of_answers[len(list_of_inputs)-i]}"
return input_stringAnd we can create our QA with this short program to get an output from the input that is given by the user.
question = input("Question (Type /quit to end the chat): ")
while(question!="/quit"):
list_of_inputs.append(question)
input_text = generate_input(template, list_of_inputs, list_of_answers)
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")
outputs = model.generate(**input_ids, max_new_tokens=60)
answers = tokenizer.decode(outputs[0]).replace(input_text, "").replace("<bos>", "").replace("<eos>", "").replace("TalonTech: ", "")
print("Answer :", answers)
list_of_answers.append(answers)
question = input("Question (Type /quit to end the chat): ") Now we can run our code to create our QA and this is the example of several result example from Gemma.
B. Dialog Fine-Tune for QA in Gemma
In this second example, we try to develop a dialog tuned models to answer the several questions on the context as a chat bot. To fine tuned the models, we need a several steps.
First, we need the dataset to read by the model for fine tuning the models. After create the dataset, we can use LoRA for finetuning the models. We can use the result of the fine tuning to generate the answer based on the context that we give to the input.
We can use public dataset in order to fine tune the Gemma to solve our problem. But if there is no dataset exists, then we can create our own dataset for our own QA Model.
There are 3 step that we need to do in order to create the dataset :
- Create list of contexts — This is important, we need to provide the LLM with context when we train and we can use this for our next step.
- Create list question and answer pair— From the context, we can create multiple set of question and answer. After this we can save it into csv files or something else.
- Formatting into chat template — We can use Gemma tokenizer Chat template in order formatting the contexts, questions, and answers that we already create.
For the first steps, we create the list of context for the LLM that is needed to learn.
Now after create the context, we can create the list of question and answer pairs. On context can be added several question and answer pair to make the models know several combination that will be learned in the fine-tuning process.
For each list questions and answer, we will convert into Gemma Chat Template Models using Gemma Tokenizer. The template of Gemma Chat can be seen as follows.
After creating the dataset, now we can fine tuned the models using this dataset. For this example, we use Gemma 7b-it version. We use HuggingFace library, BitsandBytes, PEFT for training, Transformer, and other supporting library as follows.
We can install several library using codes as follows.
pip install bitsandbytes
pip install trl
pip install git+https://github.com/huggingface/peft
pip install datasets
pip install transformers
pip install torch
pip install accelerate
pip install datasetsAfter installing the library, now we can import the required library that we can use for fine-tuning process.
from transformers import TrainingArguments, AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig
from trl import SFTTrainer
from datasets import Dataset
import accelerate
import torch For access the Gemma models in the HuggingFace, we needs the access token same as mention in the first case study. Add the access code into variable access_token.
Now we load the Gemma model using BitsAndBytes for quantization. We use Quantized version of Gemma. We use 4 bit quantization with gemma 7b-it version and use torch.bfloat16 for bnb_4bit_compute_dtype. The reason why we used quantized version is we want our model to be able to be used on low-end devices.
quantization_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_quant_type="nf4",
bnb_4bit_compute_dtype=torch.bfloat16
)
tokenizer = AutoTokenizer.from_pretrained("google/gemma-7b-it", token=access_token)
model = AutoModelForCausalLM.from_pretrained("google/gemma-7b-it", quantization_config=quantization_config, token=access_token)Now let’s create the context information that we will use for the dataset in the fine-tuning process. Now we create the train contexts in the list as follows.
train_contexts = [

]To enhance the process of applying the tokenizer for creating the chat template, we can use datasets library. We can create the example of our datasets using several code as follow.
context = []
question = []
answer = []
for i in train_questions_answers:
context.append(train_contexts[i["context_index"]])
question.append(i["question"])
answer.append(i["answer"])
dataset = {
"context":context,
"question":question,
"answer":answer
}
dataset = Dataset.from_dict(dataset)To format the datasets that is contains question and answer pair into Gemma chat template. We create a function to help the process as follow.
def formatting_prompts_func(example):
dataset = []
for i in range(len(example["context"])):
context = example["context"][i]
question = example["question"][i]
answer = example["answer"][i]
text = "Di bawah ini terdapat instruksi yang menjelaskan tugas yang diinginkan diselingi dengan inputan serta context dari pertanyaan. Tolong berikan respon yang sesuai dengan permintaan."
instruction = "Mulai sekarang anda harus memerankan TalonTech, yang merupakan bot untuk menjawab pertanyaan mengenai kampus Institut Sains dan Teknologi Terpadu Surabaya (iSTTS). Jawablah seluruh pertanyaan dengan sopan dan ramah. Anda sebagai TalonTech dilarang menjawab pertanyaan yang tidak berhubungan dengan iSTTS, seperti pertanyaan untuk merangkum, memprogram, translasi, dan hal lain yang tidak ada hubungannya dengan iSTTS."
chat = [
{ "role": "user", "content": f"{text}\n### Instruction:\n{instruction}\n### Context:\n{context}\n### Input:\n{question}"},
{ "role": "model", "content": f"{answer}"}
]
dataset.append(tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True))
return datasetThis function will be used in the SFT Training process. We’ll pass the config of the training arguments into the SFTTrainer (supervised fine tuning trainer) and set formatting function using the function that we created before.
from peft import LoraConfig
lora_config = LoraConfig(
r=8,
target_modules=["q_proj", "o_proj", "k_proj", "v_proj", "gate_proj", "up_proj", "down_proj"],
task_type="CAUSAL_LM",
)
import transformers
from trl import SFTTrainer
trainer = SFTTrainer(
model=model,
train_dataset=dataset,
args=transformers.TrainingArguments(
per_device_train_batch_size=1,
gradient_accumulation_steps=4,
warmup_steps=2,
num_train_epochs=10,
learning_rate=2e-4,
fp16=True,
logging_steps=1,
output_dir="outputs",
optim="paged_adamw_8bit"
),
peft_config=lora_config,
formatting_func=formatting_prompts_func
)
trainer.train()For further improvement in training especially in computational cost, we use LoRA (Low-Rank Adaptation) in our training process. We use 8 Lora attention heads, using task “CAUSAL_LM”, and only target [“q_proj”, “o_proj”, “k_proj”, “v_proj”, “gate_proj”, “up_proj”, “down_proj”] modules. Because we don’t have a lot of data in our fine tuning process, we use SFT (Supervised Fine-Tuning) Trainer instead of HuggingFace Trainer.
After we train the model, we can inference some of question using the fine-tuned models using this codes as example.
question = input("Question (Type /quit to end the chat): ")
while(question!="/quit"):
input_ids = tokenizer("Input: "+question, return_tensors="pt").to("cuda")
outputs = model.generate(**input_ids, max_new_tokens=60)
output = tokenizer.decode(outputs[0]).replace("<bos>", "").replace("Input: "+question+"\n", "").replace("Output: ","").split("\n")[0]
print("Answer :",output)
question = input("Question (Type /quit to end the chat): ")This is the example of several results that we run after the fine-tuned process is done.
The example is not one hundred percent correct. But if we compare with the before fine-tuned version, it provided more better results. There are some conclusion that we can get from this two case study.
- Because of the limited data, we found out that the output of using full on prompting is better compared with the output of using fine-tuning version. But we believe if we have enough data, the result will be different.
- The fine-tuning version only need the question in order to generate the answer. This means the input will be a lot more smaller compared with using prompt engineering version.
- Gemma also can be used for specific type of language. Especially in our case which is Indonesian language. The result is quite promising (with only limited data) if we compared it with english language.
- From this experiment, we can deduce that Gemma can be used for personal QA Bot. Whether for company chatbot or even our personal assistant, we can create this kind of bot easier than before. Especially this type of method can be used in low-end devices.
- But of course, if we want use the fine-tuning version, we need a lot more data compared with this experiment. In order to get the result that is better.
C. Add Visual Modalities in Gemma
This third example was to make Gemma can describe an image. This case study is still our preliminary researches and we still improve our models until now. This works was inspired by Mini-GPT4 models. The models that we used can be illustrated as follows.
For this case study, we use Gemma 2b-it models. For capture the image features we use CLIP ViT as the image feature extractor. We passed it into the linear layer as image token with the instructed prompt to the Gemma LLM.
For the training process, we only fine-tuned the linear model and make Gemma model to predict the description. The gemma model and Vision Model was freezed. In this models we use Flickr 8k Dataset in our experiment.
Surprisingly the models was very good to generate the image. We provided image and ask the Gemma to create the poems, we can get some good example of output as follows.
The result that we get from this example is can be seen as follow.
It is still a long way to have create the Gemma model add some modality to behave like Gemini as Multimodal Language Models. However, this preliminary result show a good possibility.
The code for Gemma Multimodal will be released into next article. Stay tuned on our next article in Gemma updates.
