Running Llama 3 Locally

Llama 3 with all these performance metrics is the most appropriate model for running locally. Thanks to the advancement in model quantization method we can run the LLM’s inside consumer hardware. There are different ways to run these models locally depending on hardware specifications. If your system has enough GPU memory (~48GB), you can comfortably run 8B models with full precision and a 4-bit quantized 70B model. Output might be on the slower side. You may also use cloud instances for inferencing. Here, we will use the free tier Colab with 16GB T4 GPU for running a quantized 8B model. The 4-bit quantized model requires ~5.7 GB of GPU memory, which is fine for running on T4 GPU. 

To run these models, we can use different open-source tools. Here are a few tools for running models locally.

Using HuggingFace

HuggingFace has already rolled out support for Llama 3 models. We can easily pull the models from HuggingFace Hub with the Transformers library. You can install the full-precision models or the 4-bit quantized ones. This is an example of running it on the Colab free tier.

Step1: Install Libraries

Install accelerate and bitsandbytes libraries and upgrade the transformers library.

!pip install -U "transformers==4.40.0" --upgrade
!pip install accelerate bitsandbytes

Step2: Install Model

Now we will install the model and start querying.

import transformers
import torch

model_id = "unsloth/llama-3-8b-Instruct-bnb-4bit"

pipeline = transformers.pipeline(
        "torch_dtype": torch.float16,
        "quantization_config": {"load_in_4bit": True},
        "low_cpu_mem_usage": True,

Step3: Send Queries

Now send queries to the model for inferencing.

messages = [
    {"role": "system", "content": "You are a helpful assistant!"},
    {"role": "user", "content": """Generate an approximately fifteen-word sentence 
                                   that describes all this data:
                                   Midsummer House eatType restaurant; 
                                   Midsummer House food Chinese; 
                                   Midsummer House priceRange moderate; 
                                   Midsummer House customer rating 3 out of 5; 
                                   Midsummer House near All Bar One"""},

prompt = pipeline.tokenizer.apply_chat_template(

terminators = [

outputs = pipeline(


Output of the query: “Here is a 15-word sentence that summarizes the data:

Midsummer House is a moderate-priced Chinese eatery with a 3-star rating near All Bar One.”

Step4: Install Gradio and Run Code

You can wrap this inside a Gradio to have an interactive chat interface. Install Gradio and run the code below.

import gradio as gr

messages = []

def add_text(history, text):
    global messages  #message[list] is defined globally
    history = history + [(text,'')]
    messages = messages + [{"role":'user', 'content': text}]
    return history

def generate(history):
  global messages
  prompt = pipeline.tokenizer.apply_chat_template(

  terminators = [

  outputs = pipeline(
  response_msg = outputs[0]["generated_text"][len(prompt):]
  for char in response_msg:
      history[-1][1] += char
      yield history

with gr.Blocks() as demo:
    chatbot = gr.Chatbot(value=[], elem_id="chatbot")
    with gr.Row():
            txt = gr.Textbox(
                placeholder="Enter text and press enter",

    txt.submit(add_text, [chatbot, txt], [chatbot, txt], queue=False).then(
            generate, inputs =[chatbot,],outputs = chatbot,)

Here is a demo of the Gradio app and Llama 3 in action.

Using Ollama

Ollama is another open-source software for running LLMs locally. To use Ollama, you have to download the software.

Step1: Starting Local Server

Once downloaded use this command to start a local server. 

ollama run llama3:instruct  #for 8B instruct model

ollama run llama3:70b-instruct #for 70B instruct model

ollama run llama3  #for 8B pre-trained model

ollama run llama3:70b #for 70B pre-trained

Step2: Query Through API

curl http://localhost:11434/api/generate -d '{
  "model": "llama3",
  "prompt": "Why is the sky blue?",
  "stream": false

Step3: JSON Response

You will receive a JSON response.

  "model": "llama3",
  "created_at": "2024-04-19T19:22:45.499127Z",
  "response": "The sky is blue because it is the color of the sky.",
  "done": true,
  "context": [1, 2, 3],
  "total_duration": 5043500667,
  "load_duration": 5025959,
  "prompt_eval_count": 26,
  "prompt_eval_duration": 325953000,
  "eval_count": 290,
  "eval_duration": 4709213000
