Meta has launched the primary two fashions from its Llama 4 suite: Llama 4 Maverick and Llama 4 Scout. The Maverick mannequin is designed to be a “workhorse” for common assistant and chat use instances, whereas Scout is geared extra towards “multi-document summarization, parsing in depth consumer exercise for customized duties, and reasoning over huge codebases.” The tech big additionally launched Llama 4 Behemoth, an upcoming mannequin that it claims is among the world’s smartest LLMs. Moreover, the corporate additionally talked about an upcoming fourth mannequin, Llama 4 Reasoning, to be launched in a number of weeks.
Many have been anticipating Meta to answer the “risk” posed by the rise of China’s DeepSeek, which reportedly performs on par with a number of the prime AI fashions, together with Meta’s earlier flagship Llama fashions whereas working at a fraction of the price. Whereas these claims stay contested, DeepSeek has undeniably reshaped the AI panorama. It’s no shock that Meta instantly references comparisons with DeepSeek in its weblog put up introducing Llama 4.
Meta selected to announce the newest launch properly earlier than the LlamaCon on April twenty ninth. This provides builders loads of time to obtain and experiment with the brand new fashions. Curiously, the announcement was made on a Saturday – typically a quiet slot for many tech releases. When requested on Threads concerning the weekend launch of Llama 4, Meta CEO Mark Zuckerberg merely responded, “That’s when it was prepared.”

Based mostly on the specs, the Llama 4 Maverick looks as if a extremely succesful mannequin. With 17 billion lively parameters and a complete of 400 billion parameters distributed throughout 128 specialists, it makes use of a Combination of Specialists (MoE) structure to maximise effectivity. It’s designed for effectivity, helps multimodal duties, and might be deployed on a single NVIDIA H100 DGX host.
Llama 4 Scout, then again, affords 17 billion lively parameters inside a complete of 109 billion parameters and 16 specialists. Its standout function is a ten million token context window, enabling it to deal with huge quantities of textual content or massive paperwork successfully. Scout’s effectivity permits it to run on a single NVIDIA H100 GPU.
That is the primary time MoE structure has been used for the Llama fashions. Utilizing this structure makes coaching and answering queries extra environment friendly by dividing duties into smaller items and assigning them to specialised "professional" fashions that deal with particular components.
Each Maverick and Scout can now be downloaded from the Llama web site and Hugging Face. Moreover, they’ve been built-in into Meta AI, making them accessible by way of platforms like WhatsApp, Messenger, and Instagram DMs.
“That is only the start for the Llama 4 assortment,” said Meta. “We imagine that probably the most clever techniques should be able to taking generalized actions, conversing naturally with people, and dealing by way of difficult issues they haven’t seen earlier than.”
“Giving Llama superpowers in these areas will result in higher merchandise for folks on our platforms and extra alternatives for builders to innovate on the subsequent huge shopper and enterprise use instances. We’re persevering with to analysis and prototype each fashions and merchandise, and we’ll share extra about our imaginative and prescient at LlamaCon”
The upcoming Behemoth mannequin affords extra highly effective {hardware} with 288 billion lively parameters, 16 specialists, and almost 2 trillion whole parameters. Based on Meta’s inner benchmarking, Behemoth outperforms GPT-4.5, Claude 3.7 Sonnet, and Gemini 2.0 Professional on a number of evaluations measuring STEM expertise.
Notably, not one of the Llama 4 fashions operate as full-fledged reasoning fashions like OpenAI’s o1 and o3-mini. Reasoning fashions are designed to fact-check their responses and supply extra dependable solutions, however they sometimes take longer to generate outcomes in comparison with conventional, non-reasoning fashions.
Meta shared that it has fine-turned the Llama 4 fashions to regulate how the chatbots deal with bias, particularly ”contentious units of political or social subjects”. This comes at a time when AI corporations face strain from some political figures, together with Elon Musk and David Sacks, who argue that AI chatbots usually lean towards sure ideologies. Nevertheless, AI bias appears to be a persistent and deeply rooted concern, and will not be resolved utterly anytime quickly.
In a current Instagram video, Zuckerberg stated that the corporate’s “aim is to construct the world’s main AI, open supply it, and make it universally accessible so that everybody on this planet advantages. I’ve stated for some time that I believe open-source AI goes to grow to be the main mannequin, and with Llama 4, that’s beginning to occur.”
Meta's efficiency claims for the Llama 4 collection are primarily based on outcomes from "a broad vary of broadly reported benchmarks." Notably, Maverick secured the second spot on LMArena, a well known benchmarking platform. Nevertheless, the AI group has been speaking about unverified stories suggesting that the Llama 4 mannequin examined might have been “optimized” particularly for the benchmarks, doubtlessly resulting in inflated and deceptive scores.
Ahmad Al-Dahle, VP of generative AI at Meta, has been fast to disclaim the rumors. “We've additionally heard claims that we skilled on take a look at units — that's merely not true and we might by no means try this,” shared Al-Dahle on his X account.

Al-Dahle did admit that some customers are experiencing “combined high quality” from Maverick and Scout”. He attributed these points to the early launch of the fashions, stating, “Since we dropped the fashions as quickly as they had been prepared, we count on it’ll take a number of days for all the general public implementations to get dialed in.” Al-Dahle added that the staff is actively addressing bug fixes and dealing on onboarding companions to enhance the general consumer expertise.
Whether or not Meta tried to recreation the system or not, the widespread rumors have been sufficient to forged doubts on the reliability of benchmarks. These platforms have turned extra into AI battlegrounds the place corporations compete for dominance, slightly than offering goal efficiency evaluations.
