Meta’s Partnership with Scale AI Shows Early Signs of Strain

Aug 28, 2025 | AI Trends

Since June, Meta has invested a staggering $14.3 billion into Scale AI, a data-labeling vendor, marking a significant partnership aimed at bolstering Meta Superintelligence Labs (MSL). However, just months into this relationship, there are indications that cracks are beginning to form.

Executive Departures and Internal Tensions

Notably, Ruben Mayer, Scale AI’s former Senior Vice President of GenAI Product and Operations who was brought over to assist in running MSL, has left Meta after only two months. Initially overseeing AI data operations teams, Mayer has since clarified his role, disputing claims surrounding his exclusion from Meta’s core TBD Labs, which focuses on superintelligence. He asserts that he was happy during his time at Meta and left for personal reasons.

Shift in Data Sourcing

As the partnership evolves, MSL is reportedly engaging third-party data labeling vendors, including Scale AI’s prominent competitors, Mercor and Surge, to train next-generation AI models. Although Meta has a history of working with multiple data vendors, the significant investment in Scale AI raises questions about the rationale behind collaborating with its competitors.

Despite the monetary commitment, some sources within Meta’s labs have criticized the quality of Scale AI’s data, preferring to utilize data from companies like Surge and Mercor instead. This sentiment is particularly notable given that Scale AI’s model initially relied on a low-cost, crowdsourced workforce, which may not meet the increasingly complex demands of AI development.

Challenges for Scale AI

While Scale AI has sought to attract skilled domain experts through initiatives like its Outlier platform, competitors like Mercor and Surge have built their business models on leveraging high-paid talent from the start. Following Meta’s investment announcement, Scale AI also faced challenges as layoffs were reported in similar sectors, prompting speculation about the company’s direction amid shifting market demands.

Meta’s Broader AI Ambitions

Meta’s broader ambitions in AI have compelled CEO Mark Zuckerberg to pursue aggressive strategies, including extensive data center expansions and recruiting top-tier talent from industry leaders like OpenAI and Google DeepMind. Recently, Meta launched its own AI voice startups and partnered with image generation companies, further solidifying its presence in the competitive AI landscape.

Looking Ahead

As tensions within Meta’s AI unit rise, questions linger about the viability of its partnership with Scale AI, especially since signs indicate a lack of cohesion among recent hires. The struggles highlight the complexities inherent in merging new talent with established corporate structures.

Amid these challenges, MSL is pushing forward with plans to launch its next-generation AI model by the end of this year, suggesting that despite early difficulties, Meta remains intent on advancing its AI efforts.
