Llama Models: The Most Popular Local AI
Meta's Llama is the most widely used open-weight model family in the world. The Llama 4 generation is multimodal MoE: Scout at 109B total / 17B active with 10M context, and Maverick at 400B total / 17B active, both of which want a 96GB+ Mac Studio rather than a laptop. The 3.x sizes remain the everyday local picks, from 1B and 3B on small machines up to 8B, 70B and 405B as memory allows. With the largest ecosystem of fine-tunes, tools, and community support, Llama is the safest default choice for local AI.

Frequently Asked Questions
What is the best Llama model for a MacBook?
Llama 3.2 3B for MacBook Air (8GB RAM) or Llama 3.1 8B for MacBook Pro (16GB+ RAM). The 8B model is the community favorite for general-purpose local AI.
Can Llama 70B run on a Mac?
Yes, but you need at least 48GB RAM (Mac Studio or maxed-out MacBook Pro). The Q4 quantized version uses about 42GB. Expect around 8-12 tokens per second on M4 Max. The newer Llama 4 Scout is far heavier: 67GB loaded, so a 96GB or 128GB Mac Studio.
What is the difference between Llama 3.1 and 3.2?
Llama 3.2 added small sizes (1B, 3B) optimized for edge devices and mobile. Llama 3.1 covers 8B, 70B, and 405B. For most users, pick 3.2 3B for small devices or 3.1 8B for laptops.
How does Llama compare to Qwen?
Llama has stronger general reasoning and a larger community. Qwen has more size options and better multilingual support. At 7-8B, they are close in quality. Pick based on your use case.
