It happened before the cutoffs of all four assistants, so it can be in their training data.

Key facts

  • Sutskever announced his departure on X on May 14, 2024; Leike posted ‘I resigned’ on May 15 (UTC)
  • Leike’s May 17 thread: ‘Yesterday was my last day as head of alignment, superalignment lead, and executive @OpenAI’; he said he had ‘reached a breaking point’ over core priorities
  • ‘Over the past years, safety culture and processes have taken a backseat to shiny products’; ‘OpenAI must become a safety-first AGI company’
  • Superalignment had been announced July 5, 2023 with 20% of OpenAI’s secured compute over four years; the team was dissolved (Wired, CNBC, May 17, 2024)
  • Leike joined Anthropic later in May 2024

What happened

Six months after the November 2023 board crisis, the two people leading OpenAI’s long-term alignment effort left within days of each other. Leike’s public thread said his team had been ‘sailing against the wind’ and short on compute. OpenAI folded the remaining researchers into other teams. Around the same time, reports on OpenAI’s restrictive departure agreements (non-disparagement terms tied to equity) caused further controversy.

Why it matters

It was the defining ‘safety researchers leave a frontier lab’ moment of 2024. It led directly to the ‘Right to Warn’ letter and remains a reference point for later resignations over safety, such as Jacob Coxon’s from Anthropic in September 2026.
