Meta is investing $14.3 billion in the AI company Scale, and Scale's CEO, Alexandr Wang, has joined Meta's team that works on advanced AI. This is part of Mark Zuckerberg's plan to improve Meta's AI as they compete with companies like Google and OpenAI. Scale will remain independent, but this agreement will significantly increase the business relationship between the two companies, giving Meta a 49% ownership in Scale. Wang will move to Meta with a small team but will still be on Scale's board, and Jason Droege will become the temporary CEO. This investment means Scale is valued at over $29 billion. It is not yet clear how this deal will affect Scale's other clients, such as General Motors, Toyota, and several major companies that provide large language models.
