Llama 2 License: A Guide To Open Source Model

Meta and Microsoft released Llama 2, the successor to the original Llama model, on July 18, 2023.

Furthermore, Developers can use Llama 2 to build generative AI-powered tools.

Please continue reading to learn more about Llama 2 and its license agreement.

Understanding Llama 2

Llama 2 is an open-source large language model including software, algorithms, and machine learning code.

It enables companies to build their customer models. On top of that, it is free to use.

However, the Llama 2 model is available only for research and commercial use.

Moreover, you can easily access the Llama models through Microsoft Azure Cloud, Amazon Web Services, Hugging Face, and other providers.

The Llama collection of fine-tuned and pre-trained language models ranges from 7 billion to 70 billion parameters in size, more than the previous Vlama model.

With the release of Llama 2, it could even challenge the large model GPT-4 in language performance.

Moreover, the pre-trained models offer a variety of improvements over the original Llama, such as a longer context length of 4096 tokens and being trained on 40% more tokens.

Furthermore, Llama 2 tops the other models on coding proficiency, benchmarking, and knowledge test.

Understanding Llama 2 License Agreement

Llama 2 is generally available under the LIama License, a widely used open-source software license.

Llamas 2 Licenes is subject to the following Term and conditions.

• Grant of Right:  Under Meta’s intellectual property, users are granted a non-exclusive, worldwide, non-transferable and royalty-free limited license.

Benefits Of Llama 2

Developers are still exploring and discovering the benefits of Llama 2.

Here are some benefits of Llama 2 based on its features and capabilities.

• Open-Source: Meta has provided startups and other businesses with a robust open-source model over pricy models sold by openAi and Google.
• Responsible: Researchers have trained Llama 2 to analyze potential biases and risks, making it more responsible toward safety and fairness.
• Longer Context Length: Llama 2 can process the text that is 2048 tokens.
  In comparison, the original Llama model only has 1024 tokens of processing power.
• Improved chatbot and virtual assistance: with its capabilities to understand and process the natural language.
  It can help developers to integrate more advanced chatbots and virtual assistance.

The Bottom Line

Therefore, Llama 2 is a powerful and versatile LLM that can be used for various applications.

Furthermore, Llama codes are available for commercial use under the GPL-3.0 License. However, the WEIGHT is not available.

Hopefully, this article has given you a general idea of Llama 2 and its open source License.
