Meta Unveils Llama 4 AI Models to Reclaim Leadership in the Open AI Competition

Meta has made a significant stride in the realm of artificial intelligence by launching a new generation of AI models known as the Llama 4 suite. This initiative aims to position Meta as a strong competitor against leading entities like OpenAI and Google. The introduction of these advanced models showcases Meta’s commitment to open-source AI technology.

On Saturday, April 5, Meta announced three innovative AI models — Scout, Maverick, and Behemoth. This launch represents a pivotal advancement in the company’s open-source AI efforts, with these models designed to perform a wide range of tasks that include:

• Document summarization
• Multimodal reasoning across text, images, and video

The Llama 4 models utilize a “mixture of experts” (MoE) architecture, which boosts efficiency by delegating tasks to specialized components within the system. According to Meta, their flagship model, Maverick, outperforms OpenAI’s GPT-4o and Google’s Gemini 2.0 in various benchmarks related to coding, reasoning, and image interpretation. However, it does not quite match up to OpenAI’s GPT-4.5 and Google’s Gemini 2.5 Pro, as reported by TechCrunch.

Currently, Scout and Maverick are accessible on Meta’s website and through partnerships with platforms like Hugging Face, although there are limitations on usage. Importantly, Meta has imposed restrictions on access for users and developers located in the European Union, citing the region’s stringent AI regulations and privacy laws. The company has previously criticized the EU’s regulatory approach, labeling it as excessively restrictive and detrimental to innovation.

This new release comes at a time of intense competition within the open-source AI sector, particularly in light of the rapid advancements made by the Chinese AI lab DeepSeek. Models such as R1 and V3 from DeepSeek have notably challenged the performance of Llama 2, prompting Meta to accelerate the development of Llama 4. Reports indicate that Meta has created internal “war rooms” to analyze and replicate the efficiency gains exhibited by DeepSeek.

Among the newly released models, Scout stands out as the most lightweight, featuring 17 billion active parameters and a context window of 10 million tokens. This design makes Scout particularly adept at handling lengthy documents and extensive codebases, with potential applications in:

• Academia
• Legal work
• Enterprise data analysis

Moreover, Scout is optimized for operation on a single Nvidia H100 GPU, facilitating smaller-scale deployments. In contrast, Maverick includes a staggering 400 billion parameters (with 17 billion active distributed across 128 experts) and is tailored for general-purpose AI tasks such as language comprehension and creative writing. It’s important to note that running Maverick necessitates enterprise-grade computing infrastructure, including Nvidia’s DGX systems.

Lastly, we have Behemoth, the third model, which is still undergoing training. Meta anticipates that Behemoth will outperform its competitors on STEM-related benchmarks. This model is noteworthy for its inclusion of 288 billion active parameters and nearly two trillion total parameters, making it one of the largest publicly described AI models to date. Preliminary assessments suggest that Behemoth may surpass GPT-4.5, Claude 3.7 Sonnet, and Gemini 2.0 Pro when tackling advanced mathematical and scientific challenges. However, it’s reported that Gemini 2.5 Pro may still hold an advantage in several critical areas.

In summary, the launch of the Llama 4 suite underscores Meta’s drive to innovate in the competitive AI space, with its new models potentially setting new standards for performance and efficiency. As the AI landscape continues to evolve, it will be fascinating to see how these models perform in the real world and how they stack up against the offerings from other industry leaders.
