Elon Musk's AI company, xAI, filed a 107-page complaint against OpenAI in November, accusing the ChatGPT maker of "aggressively recruiting employees with offers of lavish compensation" and spending "$1.5 billion on personnel for just 1,500 employees." The actual number of employees OpenAI has is unclear: According to the employee database RocketReach, OpenAI has 4,768 staff members. Musk alleges that OpenAI has tried to bring in more AI talent than it needs.
