Running Large Language Models on a Single GPU: How to Use Llama 13b and Openchat 13b Models

In recent times, numerous open-source large language models (LLMs) have made their debut, showcasing their immense potential for various applications. However, a major challenge arises when it comes to testing these powerful models due to limited resources. While platforms like Google Colab Pro offer the option to test up to 7B models, what can we do if we want to experiment with even larger models, such as 13B?

In this blog post, we will explore the steps to run Llama 13b and Openchat 13b models on a single GPU, specifically using Google Colab Pro’s GPU, which comes with 25 GB of system RAM. Let’s delve into the process step by step.

Step 1: Installing the Required Packages

To begin, we need to install the necessary requirements. This involves installing the accelerate and transformers packages from the source. Additionally, ensure that you have the latest version of the bitsandbytes library (0.39.0) installed. You can do this by running the following commands:

!pip install -q -U bitsandbytes
!pip install -q -U git+
!pip install -q -U git+
!pip install -q -U git+
!pip install sentencepiec

Step 2: Leveraging Quantization Technique

Our approach involves using the quantization technique, making use of the BitsAndBytes functionality from the transformers library. This technique allows us to perform quantization using various 4-bit variants, including NF4 (normalized float 4, the default) or pure FP4 quantization. With 4-bit bitsandbytes, weights are stored in 4 bits, while the computation can still occur in 16 or 32 bits. For computation efficiency during matrix multiplication and training, we recommend utilizing a 16-bit compute dtype, with the default being torch.float32.

To modify these parameters according to specific requirements, we can take advantage of the recently introduced BitsAndBytesConfig in transformers. Here’s an example of configuring the quantization:

import torch
from transformers import BitsAndBytesConfig
from transformers import AutoModelForCausalLM, AutoTokenizer

quantization_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_compute_dtype=torch.bfloat16
)

Step 3: Loading the Tokenizer and Model

Once we’ve added the configuration, the next step is to load the tokenizer and model. In this example, we are using the Openchat model, but you can use any 13b model available on the HuggingFace Model Hub. If you prefer to use the Llama 13 model, simply change the model-id to “openlm-research/open_llama_13b” and follow the same steps below:

model_id = “openchat/openchat_8192”
tokenizer = AutoTokenizer.from_pretrained(model_id)
model_bf16 = AutoModelForCausalLM.from_pretrained(model_id, quantization_config=quantization_config)

Step 4: Testing the Model

Once the model is loaded, it’s time to test it. You can provide any input of your choice and adjust the “max_new_tokens” parameter to specify the number of tokens you want to generate. Here’s an example:

text = “Q: What is the largest animal?nA:”
device = “cuda:0″
inputs = tokenizer(text, return_tensors=”pt”).to(device)
outputs = model_bf16.generate(**inputs, max_new_tokens=35)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Output:
You can utilize this quantization technique to work with any 13b model using a single GPU or Google Colab Pro. Enjoy exploring the capabilities of large language models for your applications!
