What Are Llama 2 Models?
Llama 2 models are advanced Large Language Models (LLMs) developed by Meta AI. They range in size from 7 billion to 70 billion parameters and are designed for diverse applications like content creation, coding, and conversational AI.
Key Features:
- Open-source: Available for both research and commercial use.
- Variations: Includes Llama Chat for dialogue tasks and Code Llama for programming assistance.
- Training: Trained on 2 trillion tokens for a deep understanding of various subjects.
Key Benefits of Running Llama 2 Locally
Privacy: Keep your data secure by avoiding cloud-based processing.
Offline Accessibility: Use Llama 2 without internet connectivity.
Customization: Tailor the model’s performance to your specific needs.
Cost Efficiency: Eliminate recurring cloud-computing costs.
