Meta Delays 'Behemoth' AI Model Launch Amid Concerns

Imagine the tech world buzzing with anticipation—after all, Meta’s “Behemoth” was supposed to be the next big leap in artificial intelligence. But as of June 2025, the wait for the largest Llama 4 model, internally dubbed “Behemoth,” just got longer. The Wall Street Journal and other reputable outlets report that Meta has pushed back the release of its flagship AI model, citing concerns that its advancements might not justify the hype[1][4][5]. What does this delay mean for the broader AI landscape, for Meta’s position in the industry, and for the millions of users who interact with AI every day? Let’s unpack the latest developments and what’s really at stake.

The Behemoth Delay: What Happened?

Meta’s Behemoth was initially slated to debut at the company’s first-ever LlamaCon event in April 2025. But the launch was first postponed to June and, as recent reports confirm, now faces yet another delay—potentially until fall or later[1][4][5]. According to sources familiar with the matter, Meta’s engineers are struggling to deliver performance that significantly outpaces previous models, particularly Llama 4, which was released in April[4][5].

In public statements, Meta has touted Behemoth as “one of the smartest LLMs in the world and our most powerful yet,” designed to serve as a “teacher” for future models[4][5]. Yet, behind the scenes, training difficulties and underwhelming improvements have reportedly led to internal doubts. “We’re also previewing Llama 4 Behemoth, one of the smartest LLMs in the world and our most powerful yet to serve as a teacher for our new models,” Meta said in its April press release[4][5]. But for now, those previews are on hold.

The Bigger Picture: Why This Matters

Meta’s delay is more than just a scheduling hiccup—it’s a symptom of deeper challenges facing the AI industry. The “bigger is better” mantra that has driven much of the recent AI arms race may be hitting a wall. The Wall Street Journal and other analysts note that companies like OpenAI, Google, and Anthropic are also encountering setbacks in training their largest models[1][2][5]. For example, OpenAI’s much-anticipated GPT-5 was originally expected in mid-2024 but has been delayed, with interim models like GPT-4.5 filling the gap for now[2].

Let’s face it—scaling up models isn’t as straightforward as it once seemed. There are technical hurdles, sure, but there’s also a growing concern about running out of high-quality training data. As one report puts it, “Large language models require massive amounts of data to train on, such as the entire internet. But they may be running out of publicly available data to access, while copyrighted content carries legal risks”[2]. This has led companies like OpenAI, Google, and Microsoft to lobby governments for clearer rules on using copyrighted material for AI training[2].

The Technical and Business Challenges

Meta’s challenges with Behemoth mirror broader industry struggles. Training a model of this size is a monumental task, requiring billions of dollars in investment and vast computational resources[1][5]. Meta CEO Mark Zuckerberg recently announced plans to increase spending on AI data centers, underscoring the company’s commitment to maintaining its edge[5]. But even with these investments, the path to a genuinely breakthrough model is anything but certain.

One of the most pressing issues is the quality and availability of training data. As models grow larger, they need more and better data to improve. But the internet is a finite resource, and much of the remaining data is either low-quality or legally ambiguous[2]. This has led to a scramble for new data sources and, in some cases, legal battles over copyright and fair use.

Another challenge is the diminishing returns on model size. Early gains from scaling up were dramatic, but now each increase in model size delivers smaller and smaller improvements in performance. This phenomenon, sometimes called “the scaling plateau,” is now being openly discussed by AI researchers and industry leaders[1][2].

Real-World Applications and User Impact

Meta’s AI models already power a wide range of features across Facebook, Instagram, WhatsApp, and Messenger, from helping users write posts and captions to editing images[4]. The company also launched a standalone Meta AI app in late April, which includes a hub for its Ray-Ban smart glasses[4]. These tools are becoming increasingly central to how billions of people interact online.

But what happens when the next big model is delayed? For most users, the impact may be minimal—at least in the short term. The current generation of AI tools is already highly capable, and many users may not notice the difference between Llama 4 and Behemoth in their daily interactions[2][4]. However, for developers and businesses building on top of Meta’s AI infrastructure, delays can mean postponed features, missed opportunities, and increased uncertainty.

Industry Comparisons: Who’s Ahead and Who’s Behind?

To put Meta’s delay in context, it’s worth looking at how other major players are faring. Here’s a quick comparison of recent developments from the leading AI companies:

As you can see, Meta isn’t alone in facing delays. OpenAI’s GPT-5 is also behind schedule, and Google and Anthropic have encountered their own setbacks[1][2][5]. This suggests that the entire industry is grappling with the limits of current approaches.

The Future of AI: What’s Next?

So, what does all this mean for the future of artificial intelligence? For starters, the era of easy gains from simply making models bigger may be coming to an end. Researchers and companies are now exploring alternative strategies, such as improving data quality, developing more efficient training methods, and focusing on specialized models for specific tasks[1][2].

OpenAI, for example, has shifted to releasing a series of more specialized models—some optimized for reasoning, others for coding or technical work—rather than a single, all-purpose giant[1]. This approach may become more common as the industry adapts to the realities of the scaling plateau.

Meta, meanwhile, is doubling down on its investments in AI infrastructure, with plans to build new data centers and expand its computational capabilities[5]. The company’s long-term strategy appears to be to stay in the race, even as the finish line keeps moving.

Personal Perspective: The Human Side of AI Progress

As someone who’s followed AI for years, I’ve seen plenty of hype cycles come and go. But this moment feels different. The challenges we’re seeing now—data scarcity, legal uncertainty, diminishing returns—are real and persistent. It’s a reminder that progress in AI, like in any field, isn’t always linear or predictable.

There’s also a human side to these delays. For engineers and researchers working on these models, the pressure to deliver breakthroughs is intense. And for the rest of us, the promise of smarter, more helpful AI tools is tantalizing—but it’s worth remembering that building the future takes time.

Conclusion and Forward-Looking Insights

Meta’s delay of the Behemoth AI model is a significant moment in the ongoing evolution of artificial intelligence. It underscores the challenges facing the industry as it pushes the boundaries of what’s possible with large language models. While the immediate impact on users may be limited, the delay signals a broader shift in how companies approach AI development—from a focus on sheer size to a more nuanced strategy that emphasizes data quality, efficiency, and specialization.

Looking ahead, the AI landscape is likely to become more diverse, with a mix of general-purpose and specialized models working together to power the next generation of applications. The race isn’t over—it’s just getting more interesting.
