The AI Talent Wars

Competition for AI talent has reached unprecedented levels. Anthropic is emerging as a leader in the talent wars, with engineers from OpenAI being 8x more likely to leave for Anthropic, while at DeepMind, that ratio is nearly 11:1 in Anthropic's favor.

Top AI researchers command compensation packages exceeding $1M annually. Companies are acquiring entire research teams through "acquihires" and offering unprecedented equity packages to attract talent.

Notable moves in 2024-2025: Jan Leike (OpenAI → Anthropic), Ilya Sutskever (OpenAI → SSI), Mustafa Suleyman (DeepMind → Microsoft)
