OpenAI is phasing out its partnership with Scale AI following Meta's announcement to acquire a 49% stake in the AI training data provider for nearly $15 billion. This acquisition marks Meta's second-largest in its history. As a result, Scale AI's CEO will join Meta's experimental AI project. In response, OpenAI is shifting towards new suppliers like Mercor for specialized data. Similarly, Google is reportedly reducing its collaboration with Scale AI over concerns about potential exposure of trade secrets to competitors.
