Meta just dropped a major update in the AI arms race—and it’s not subtle.
On April 5, the tech giant behind Facebook, Instagram, and WhatsApp released two powerful AI models under its new Llama 4 series: Llama 4 Scout and Llama 4 Maverick. Both models are part of Meta’s bold bet on open-source multimodal intelligence—AI that doesn’t just understand words, but also images, audio, and video.
And here’s the kicker: They’re not locked behind some secretive corporate firewall. These models are open-source, ready for the world to build on.
What’s New in Llama 4?
Llama 4 Scout
With 17 billion active parameters and a 10 million-token context window, Scout is designed to be nimble and efficient. It runs on a single Nvidia H100 GPU, making it accessible for researchers and developers who aren’t operating inside billion-dollar data centers. Scout’s sweet spot? Handling long documents, parsing context-rich queries, and staying light on compute.
Llama 4 Maverick
Think of Maverick as Scout’s smarter, bolder sibling. Also featuring 17 billion active parameters, Maverick taps into 128 experts using a Mixture of Experts (MoE) architecture. The result: blazing-fast reasoning, enhanced generation, and an impressive 1 million-token context window. In short, it’s built to tackle the big stuff—advanced reasoning, multimodal processing, and large-scale data analysis.
Llama 4 Behemoth (Coming Soon)
Meta teased its next heavyweight: Llama 4 Behemoth, a model with an eye-watering 288 billion active parameters (out of a total pool of 2 trillion). It’s still in training but is intended to be a “teacher model”—a kind of AI guru that could power future generations of smarter, more adaptable systems.
The Multimodal Revolution Is Here
Unlike earlier iterations of Llama, these models aren’t just text wizards. Scout and Maverick are natively multimodal—they can read, see, and possibly even hear. That means developers can now build tools that fluently move between formats: converting documents into visuals, analyzing video content, or even generating images from written instructions.
Meta’s decision to keep these models open-source is a shot across the bow in the AI race. While competitors like OpenAI and Google guard their crown jewels, Meta is inviting the community to experiment, contribute, and challenge the status quo.
Efficiency Meets Power
A key feature across both models is their Mixture of Experts (MoE) setup. Instead of activating the entire neural network for every task (which is computationally expensive), Llama 4 models use only the “experts” needed for the job. It’s a clever way to balance performance with efficiency, especially as the demand for resource-intensive AI continues to explode.
Why It Matters
Meta’s Llama 4 release isn’t just another model drop—it’s a statement.
With Scout and Maverick, Meta is giving the developer community real tools to build practical, powerful applications—without breaking the bank. And with Behemoth on the horizon, the company is signaling it’s in this game for the long haul.
From AI-generated content and customer support to advanced data analysis and educational tools, the applications for Llama 4 are vast. More importantly, the open-source nature of these models means they won’t just belong to Meta—they’ll belong to all of us.
Whether you’re a solo developer, startup founder, or part of a global research team, the Llama 4 models are Meta’s invitation to help shape the next era of artificial intelligence.
And judging by what Scout and Maverick can already do, the future is not just coming—it’s open.
