The Llama Series: Meta's Evolution in AI Language Models

Meta's Llama series stands as a testament to rapid AI evolution, marking its territory since February 24, 2023. Under the guidance of Meta's leadership, including CEO Mark Zuckerberg and Chief AI Scientist Yann LeCun, these models have transformed from promising beginners to industry powerhouses.

The Power of Scale

The Llama family tree shows impressive growth in capabilities:

• Llama 1: Started with models from 7B to 65B parameters

• Llama 2: Refined the approach with 7B, 13B, and 70B versions

• Llama 3: Introduced 8B and 70B parameter models

• Llama 3.1: Pushed boundaries with a massive 405B parameter model

This progression isn't just about numbers - it's about exponential growth in understanding and capability.
