Among these, the Llama-2-Chat models, optimized for dialogue, shine as they outperform open-source chat models across various benchmarks. In fact, their helpfulness and safety evaluations rival some popular closed-source models like ChatGPT and PaLM. 

In this blog, we will exploring its training process, improvements over its predecessor, and ways to harness its potential.



If you want to use it in your projects, this guide will get you started.

So, let us embark on this journey together as we unveil the world of Llama 2 and discover how it can elevate your AI (Artificial Intelligence) endeavors. 


Llama 2: The evolution and enhanced features 


It represents a significant leap forward from its predecessor, Llama 1, which garnered immense attention and demand from researchers worldwide. With over 100,000 requests for access, the research community demonstrated its appetite for powerful language models.

Building upon this foundation, Llama 2 emerges as the next generation offering from Meta, succeeding its predecessor, Llama 1. Unlike Llama 1, which was released under a non-commercial license for research purposes, it takes a giant stride by making itself available freely for both research and commercial applications.

This second-generation model comes with notable enhancements, including pre-trained versions with parameter sizes of 7 billion, 13 billion, and a staggering 70 billion. Llama 2’s training data has been expanded, encompassing 40% more information, all while boasting double the context length compared to Llama 1, with a context length of 4,096 tokens.


Notably, the Llama-2 chat models, tailored for dialogue applications, have been fine-tuned with the assistance of over 1 million new human annotations. As we delve deeper, we will explore its capabilities and the numerous ways to access this remarkable language model. 



Exploring your path to Llama 2: Six access methods you must learn 

Accessing the power of it is easier than you might think, thanks to its open-source nature. Whether you are a researcher, developer, or simply curious, here are six ways to get your hands on the Llama 2 model right now:

Its models are also available in the Hugging Face organization of Llama 2 from Meta. All the available models are accessible there as well. To use these models from Hugging Face, we still need to submit a download request to Meta, and additionally, we need to fill out a form to enable the use of Llama 2 in Hugging Face.

To access its models on Hugging Face, follow these steps:


Meta Llama2 Organization HuggingFace


  • You can see a “Models” tab on the page which lists all the available models. 


Access Llama2 HuggingFace



  • In the Access Llama 2 on Hugging Face card enter the email you used to send out the download request. 

Note: Please ensure that the email you use on Hugging Face matches the one you used to request Llama 2 download permission from Meta. 


Utilize the quantized model from Hugging Face 

In addition to the models from the official Meta Llama 2 organization, there are some quantized models also available on Hugging Face. 

If you search for Llama in the Hugging Face search bar. You will see a list of models available in Hugging Face. You can see that models from meta-llama the official organization are available but there are other models also available.

These models are the quantized version of the same Llama 2 models. Like the model, TheBloke/Llama-2-7b-Chat-GGUF contains GGUF format model files for Meta Llama 2’s Llama 2 7B Chat. 





The key advantage of these compressed models lies in their accessibility. They are open-source and do not necessitate users to request downloads from either Meta or Hugging Face. Although they are not the complete, original models, these quantized versions allow users to harness the capabilities of the model with reduced computational requirements. 




Deploy Llama 2 on Microsoft Azure 

Microsoft and Meta have strengthened their partnership, designating Microsoft as the preferred partner for Llama 2. This collaboration brings Llama 2 into the Azure AI model catalog, granting developers using Microsoft Azure the capability to seamlessly integrate and utilize this powerful language model.

Within the Azure model catalog, you can effortlessly locate the Llama 2 model developed by Meta. Microsoft Azure simplifies the fine-tuning of Llama 2, offering both UI-based and code-based methods to customize the model according to your requirements. Furthermore, you can assess the model’s performance with your test data to ascertain its suitability for your unique use case. 


Harness Llama 2 as a cloud-based API 

Another avenue to tap into the capabilities of the Llama 2 model is through the deployment of Llama 2 models on platforms such as Hugging Face and Replicate, transforming it into a cloud API. By leveraging the Hugging Face Inference Endpoint, you can establish an accessible endpoint for your Llama 2 model hosted on Hugging Face, facilitating its utilization.
