Llama (Meta’s Llama 2 & 3)
Llama
Description: LLaMA (Large Language Model Meta AI), developed by Meta AI, is a series of efficient, research-oriented LLMs released in 2023. Unlike consumer-facing models like ChatGPT, LLaMA (e.g., LLaMA-13B, LLaMA-70B) was designed for academic and experimental use, boasting high performance in NLP tasks with fewer computational resources. Its lightweight design and open availability (for research purposes) have made it a favorite for fine-tuning and deployment in custom applications. LLaMA’s successors, like LLaMA 2 and 3, further improved its capabilities, competing with larger models while maintaining efficiency.
Key Features:
Ranges from 7B to 70B parameters.
Fine-tuned for chat (Llama-2-Chat).
Available via Meta’s partnership with Microsoft Azure.
Use Cases: Chatbots, research and enterprise AI.
