The Initial Investment: Meta's Big Bet on Scale AI
Back in June 2025, Meta made what seemed like a strategic masterstroke by investing $14.3 billion for a 49% stake in Scale AI. This valued the data-labeling specialist at a whopping $29 billion – not bad for a company that had raised $1 billion just a year earlier at a $13.8 billion valuation. The deal brought Scale AI's CEO Alexandr Wang over to Meta to help with their AI work, while Scale's chief strategy officer Jason Droege stepped in as interim CEO .
At the time, the move made perfect sense. Meta had been playing catch-up with AI rivals like Google, OpenAI, and Anthropic. Reports indicated they'd lost 4.3% of their top AI talent to competitors just in the previous year. Scale AI had established itself as a critical partner to leading AI labs, providing the labeled data needed to train sophisticated large language models. By bringing Scale AI's capabilities in-house, Meta hoped to accelerate its AI development and close the gap with competitors .
The investment money was apparently used to pay investors and shareholders while also fueling growth. Scale AI emphasized that it would remain an independent entity despite the massive investment, with Wang staying on as a director on the company's board . On the surface, it looked like a win-win situation – Meta gained expertise and data capabilities, while Scale AI secured resources and a powerful partner.
Executive Movement: Who's In, Who's Out
The leadership changes following the deal have been anything but stable. Alexandr Wang's move to Meta was undoubtedly the most high-profile transition. He joined as chief AI officer and now leads the TBD Labs group within Meta's reorganized AI division . This group focuses on foundation models like the Llama series, which had its latest release in April .
But not all executive transitions have gone smoothly. Ruben Mayer, Scale AI's former Senior Vice President of GenAI Product and Operations, departed Meta after just two months with the company . Mayer had spent roughly five years with Scale AI across two stints, so his quick exit raised eyebrows.
There's some disagreement about Mayer's role and departure. Mayer himself claims he was "part of TBD Labs from day one" and that his initial position was "to help set up the lab, with whatever was needed" rather than focusing specifically on data operations. He also noted that he "did not report directly to [Wang]" and was "very happy" with his Meta experience . Despite his positive spin, such a short tenure suggests possible friction or misalignment about responsibilities.
The executive movement hasn't been one-way either. Meta has been aggressively recruiting top AI researchers from organizations like Google DeepMind and OpenAI . This includes people who've worked on Google's most powerful AI models . But retaining this talent has proven challenging – several researchers recently brought in from OpenAI have already left Meta, according to Wired .
Data Quality Concerns: The Core Issue
Perhaps the most significant challenge in the Meta-Scale AI partnership revolves around data quality concerns. Despite Meta's massive investment, researchers at Meta's TBD Labs have expressed a clear preference for working with Scale AI's competitors – specifically Surge AI and Mercor .
Five people familiar with the matter confirmed that TBD Labs is working with third-party data labeling vendors other than Scale AI to train its upcoming AI models . This is particularly notable because AI labs commonly work with several data labeling vendors simultaneously. What makes this situation unusual is that despite Meta's multi-billion-dollar investment in Scale AI, their researchers apparently see Scale AI's data as low quality compared to what competitors offer .
The root of this quality issue might lie in Scale AI's business model origins. The company initially built its business on a crowdsourcing approach that used a large, low-cost workforce to handle simple data labeling tasks . But as AI models have grown more sophisticated, they now require highly-skilled domain experts – doctors, lawyers, scientists – to generate and refine the high-quality data needed for improvement .
Scale AI has tried to adapt with its Outlier platform, designed to attract these subject matter experts . However, competitors like Surge AI and Mercor have been growing quickly because their business models were built from the ground up on a foundation of high-paid talent . This potentially gives them an edge in data quality that's hard to overcome quickly.
A Meta spokesperson disputed the claim that there are quality issues with Scale AI's product . When asked about Meta's deepening reliance on competing data providers, a Scale AI spokesperson directed TechCrunch to the initial announcement of Meta's investment, which cited an expansion of the companies' commercial relationship .
Strategic Shifts: Meta's Partnership Dilemma
In a telling development, Meta has been exploring partnerships with both Google and OpenAI to integrate their AI models into Meta's applications . This suggests that despite their massive investment in Scale AI and the creation of their Superintelligence Lab, Meta leadership wants to enhance their AI offerings quickly while they develop their next-generation models like Llama 5 .
Discussions have included using Google's Gemini model to power conversational, text-based responses for Meta AI, the company's primary chatbot. Talks have also covered leveraging OpenAI's models for Meta AI and other AI features within Meta's social apps . A Meta spokesperson confirmed the company's "all-of-the-above approach" to AI development, which includes building world-leading models themselves, partnering with companies, and open-sourcing technology .
These potential partnerships would likely be temporary measures to improve Meta's AI products until their own models can compete with rivals . But they also indicate that Meta isn't putting all their eggs in the Scale AI basket, despite the enormous investment. The company appears to be hedging its bets, recognizing that multiple approaches might be necessary to compete effectively in the rapidly evolving AI landscape .
This strategic flexibility comes amid significant internal reorganization of Meta's AI efforts. The company has torn down its existing AI org and restructured it into four new groups under the banner of Meta Superintelligence Labs (MSL) . The centerpiece is Wang's TBD Labs group, with the other three groups focusing on research, product integration, and infrastructure respectively .
Talent Turmoil: Recruitment and Retention Challenges
Meta's AI unit has become increasingly chaotic since bringing on Wang and a wave of top researchers, according to two former employees and one current MSL employee . New talent from OpenAI and Scale AI have expressed frustration with navigating the bureaucracy of a large company, while members of Meta's previous GenAI team have seen their scope limited .
The departure of MSL AI researcher Rishabh Agarwal illustrates the retention challenges. Agarwal posted on X that he'd be leaving the company, noting that "The pitch from Mark and @alexandr_wang to build in the Superintelligence team was incredibly compelling" but ultimately he decided to "follow Mark's own advice: 'In a world that's changing so fast, the biggest risk you can take is not taking any risk'" .
Other recent departures include Chaya Nayak, director of product management for generative AI, and research engineer Rohan Varma . This talent churn raises questions about whether Meta can stabilize its AI operations and retain the expertise needed for future success .
Meanwhile, Scale AI has faced its own challenges following the Meta investment. Not long after the deal was announced, OpenAI and Google said they would stop working with the data provider . This led Scale AI to lay off 200 employees in its data labeling business in July 2025, with CEO Jason Droege blaming "shifts in market demand" . The company said it would staff up in other areas, including government sales – they recently landed a $99 million contract with the U.S. Army .
Infrastructure and Technical Hurdles
Beyond partnership and talent challenges, Meta faces significant technical hurdles in their AI ambitions. The company has committed enormous resources to AI infrastructure, recently announcing several massive data center buildouts across the U.S. . One of the largest is a $50 billion data center in Louisiana called Hyperion, named after a titan in Greek mythology that fathered the God of Sun .
Meta's global AI infrastructure consists of countless hardware components and servers connected via network fabric across globally distributed data centers . This setup integrates storage, compute, and network architectures with unique file systems and PyTorch applications tailored for training or inference workloads .
A significant technical challenge involves hardware reliability. Hardware faults can dramatically impact AI training and inference, particularly silent data corruptions (SDCs) – undetected data errors caused by hardware . These can be especially harmful for AI systems that rely on accurate data for training and providing useful outputs .
Since 2018, Meta's hardware reliability efforts have identified unique failure types in disks, CPUs, memories, switches, GPUs, ASICs, and networks . They've often led the industry in discovering failure modes and developing mitigation policies to ensure smooth infrastructure operation .
Training large-scale models involves thousands of accelerators working synchronously, where any component failure can interrupt or halt the process . From their experience running the Llama 3 herd of models, Meta found that hardware failures in components like SRAMs, HBMs, processing grids, and network switch hardware significantly impact AI cluster reliability . Over 66% of training interruptions stem from such failures .
Market Context and Future Implications
Meta's AI ambitions come amid intense competition in the AI assistant space. Despite the internal challenges, Meta AI has grown to 1 billion monthly active users across Meta's apps as of Q1 2025, making it the second-largest AI assistant worldwide behind only ChatGPT . This represents remarkable growth from 500 million users in late 2024 – a 100% increase in just months .
Most of this growth didn't come from tech enthusiasts but everyday people using AI inside their favorite apps like WhatsApp, Instagram, and Facebook . Nearly two-thirds (63%) of Meta AI engagements occur on WhatsApp, with India being Meta AI's largest and most active market .
Despite this impressive user base, Meta AI holds an estimated 15-20% share of the global AI chatbot market, significantly behind ChatGPT's 60.4% share . Other competitors like Microsoft Copilot (14.3%) and Google Gemini (13.5%) also represent substantial market forces .
The question now is whether Meta can stabilize its AI operations and retain the talent needed for future success . MSL has already started working on its next generation AI model, aiming to launch by the end of 2025 . The outcome of this effort could determine whether Meta's $14.3 billion bet on Scale AI pays off or becomes a cautionary tale about the challenges of integrating acquired AI capabilities.
Some initially speculated that Meta's investment in Scale AI was really about luring Alexandr Wang, a founder with extensive AI experience since Scale's 2016 founding . Wang appears to be helping Meta attract top AI talent, but there's an open question around how valuable Scale AI itself is to Meta beyond this recruitment function .
Lessons for the AI Industry
The Meta-Scale AI partnership offers several broader lessons for the AI industry. First, it highlights the critical importance of data quality in AI development. Even the most advanced models struggle when trained on flawed or insufficient data . As AI models grow more sophisticated, their data requirements evolve from simple labeling to expert-generated content – a transition that some data providers manage better than others .
Second, the situation demonstrates the challenges of integrating acquired AI capabilities into larger organizations. Cultural clashes, bureaucracy frustrations, and talent retention issues can undermine even the most promising partnerships . Companies pursuing similar strategies should anticipate these challenges and develop plans to address them.
Third, the Meta-Scale AI story illustrates the complex dynamics of competition and collaboration in the AI space. Meta's exploration of partnerships with Google and OpenAI while simultaneously competing with them shows how tech giants are pursuing multiple parallel strategies to avoid falling behind in the AI race .
Finally, the episode highlights the enormous resources required to compete at the forefront of AI development. Meta's massive investment in Scale AI, combined with its billions in infrastructure spending and aggressive talent acquisition, shows how capital-intensive the AI arms race has become . This could have concerning implications for smaller players and potential market concentration.
As the AI industry continues to evolve at breakneck speed, the Meta-Scale AI partnership will serve as an interesting case study in the opportunities and pitfalls of strategic partnerships in this rapidly changing landscape. The coming months will reveal whether Meta can overcome the current challenges and leverage its investment to truly compete with AI leaders like OpenAI and Google.
