Cracks Emerge in Meta-Scale AI Partnership

Key Facts

  • Meta invested $14.3 billion in Scale AI in June 2025.
  • Ruben Mayer, a former Scale AI executive, left Meta after just two months.
  • Meta's TBD Labs are working with Scale AI competitors Mercor and Surge for data.
  • Some researchers at TBD Labs reportedly view Scale AI's data as low quality.
  • Scale AI's original business model relied on crowdsourcing for data annotation.

Why You Care

Ever wonder if big tech partnerships always go as planned? What happens when a multi-billion dollar investment starts to fray just months in? Meta, the tech giant, recently poured a significant sum into Scale AI. However, early indicators suggest this relationship might be more complex than initially thought. This news directly impacts how future AI models are trained. It could also influence your daily interactions with AI-powered services.

What Actually Happened

Meta invested a substantial $14.3 billion in Scale AI in June. This investment brought Scale AI CEO Alexandr Wang and other top executives to Meta Superintelligence Labs (MSL), according to the announcement. However, the partnership is already showing signs of strain. Ruben Mayer, former Senior Vice President of GenAI Product and Operations at Scale AI, has departed Meta. He left after only two months with the company, as detailed in the blog post.

Mayer’s role at Meta was reportedly to oversee AI data operations teams. He disputes some details about his position, telling TechCrunch that his initial role was “to help set up the lab, with whatever was needed.” He also stated he was “part of TBD labs from day one.” This core unit, TBD Labs, is tasked with building AI superintelligence. It has attracted top AI researchers from OpenAI, the team revealed.

Why This Matters to You

This creation is significant for the future of artificial intelligence. It highlights the complexities of building AI models. Meta’s TBD Labs are now working with third-party data vendors. These include Mercor and Surge, according to five people familiar with the matter. These companies are major competitors to Scale AI.

Imagine you are a content creator relying on AI for generating text or images. The quality of the data used to train these models directly impacts their performance. If the data is low quality, your AI outputs might suffer. This situation demonstrates the essential need for diverse, high-quality training data.

“While AI labs commonly work with several data vendors – Meta has been working with Mercor and Surge since before TBD Labs was spun up – it’s rare for an AI lab to invest so heavily in one data vendor,” the paper states. This makes the current situation particularly notable. Even with Meta’s huge investment, some researchers in TBD Labs reportedly view Scale AI’s data as low quality. They have expressed a preference to work with Surge and Mercor, the company reports.

What does this mean for the reliability of future AI systems? How will this affect your trust in AI-generated content?

The Surprising Finding

Here’s the twist: despite Meta’s massive financial commitment to Scale AI, researchers within Meta’s own TBD Labs reportedly have concerns. They find Scale AI’s data to be of “low quality.” This is a surprising revelation, given the $14.3 billion investment made just a few months ago. It challenges the assumption that a large investment automatically guarantees satisfaction or exclusivity. It suggests that even deep financial ties cannot overcome fundamental issues like data quality. This finding indicates a potential disconnect between investment strategy and operational needs. It also highlights the evolving demands of AI training. Scale AI initially focused on crowdsourcing for simple data annotation. However, modern AI models need highly-skilled domain experts. These experts include doctors, lawyers, and scientists. They generate and refine the specialized data needed for better performance, the technical report explains.

What Happens Next

The future will likely see Meta continuing to diversify its data sources. TBD Labs will likely deepen its engagements with vendors like Mercor and Surge. This strategy aims to ensure high-quality data for its upcoming AI models. We might see more personnel shifts as Meta refines its AI creation teams. This could happen over the next few quarters.

For example, imagine a new AI assistant from Meta. Its capabilities will directly depend on the quality of its training data. If Meta secures superior data, your interactions with this assistant will be smoother and more accurate. Companies relying on AI models should constantly evaluate their data pipelines. They should also consider diversifying their data suppliers. This situation underscores the dynamic nature of AI creation. It shows that even well-established partnerships can face unexpected challenges. The industry implications are clear: data quality remains paramount for AI progress. The team revealed that researchers prioritize data utility over investment ties.
