Meta Has Released Its First Llama 4 Family of AI Models

Meta introduced the first artificial intelligence (AI) models in the Llama 4 family on Saturday. The Menlo Park-based tech giant released two models — Llama 4 Scout and Llama 4 Maverick — with native multimodal capabilities to the open community. The company says these are the first open models built with Mixture-of-Experts (MoE) architecture. Compared to the predecessor, these come with higher context windows and better power efficiency. Alongside, Meta also previewed Llama 4 Behemoth, the largest AI model in the family unveiled so far.

In a blog post, the tech giant detailed its new AI models. Just like the previous Llama models, the Llama 4 Scout and Llama 4 Maverick are open-source AI models and can be downloaded via its Hugging Face listing or the dedicated Llama website. Starting today, users can also experience the Llama 4 AI models in WhatsApp, Messenger, Instagram Direct, and on the Meta.AI website.

The Llama 4 Scout is a 17 billion active parameter model with 16 experts, whereas the Maverick model comes with 17 billion active parameters and 128 experts. Scout is said to be able to run on a single Nvidia H100 GPU. Additionally, the company claimed that the previewed Llama 4 Behemoth outperforms GPT-4.5, Claude Sonnet 3.7, and Gemini 2.0 Pro on several benchmarks. Meta said the Behemoth model, with 288 billion active parameters and 16 experts, was not released as it is still being trained.
