LLaMA 2

LLaMA 2 is a family of large language models (LLMs) developed by Meta.

• Open-Source (with restrictions): LLaMA 2 is available under a permissive license for research and commercial use, making it more accessible than many other advanced LLMs.
• Improved Performance: Trained on a significantly larger dataset than its predecessor (LLaMA 1), LLaMA 2 demonstrates improved performance across various benchmarks, including code generation and reasoning.
• Multiple Sizes: Available in various sizes (7B, 13B, and 70B parameters), allowing users to choose the model that best suits their needs and computational resources.
• Chat Models: Includes pre-trained chat models that are specifically optimized for conversational AI applications.

Note: While open-source, LLaMA 2 has restrictions on its use, particularly for high-risk applications and those that could potentially cause harm.
