Meta Launches Llama 4: All About the Latest Open-Source AI Model

Meta Launches Llama 4: In a strategic move to strengthen its foothold in the generative AI space, Meta on Saturday released the first model from its latest open-source AI suite, Llama 4.

In an Instagram video, Meta CEO Mark Zuckerberg shared the company’s AI ambitions: “Our goal is to build the world’s leading AI, open source it, and make it universally accessible… I’ve said for some time that open-source AI will move in this direction, and with Llama 4, we’re starting to see it happen.”

The two initial models – Llama 4 Scout and Llama 4 Maverick – are now available for download via the Llama website and Hugging Face. These models also serve as the basis for Meta AI, the company’s virtual assistant that’s now integrated into WhatsApp, Instagram, Messenger, and the web.

Additionally, Meta introduced Llama 4 Behemoth, describing it as one of the smartest Large Language Models (LLM) ever built and the most powerful version they have ever developed. It is intended to help train and guide future models.

This rollout also marks Meta’s first use of the Mixture of Experts (MoE) framework. MoE divides the model into specialized components – each focused-on area such as physics, poetry, biology, or programming. During any given task, only the most relevant expert modules are activated, increasing efficiency and reducing costs for training and inference.
