Future of Life Institute (FLI) — campaign: Pause Giant AI Experiments Open Letter (March 2023): called for a 6-month moratorium on training AI systems more powerful than GPT-4. 33,000+ signatories including Yoshua Bengio, Stuart Russell, Steve Wozniak, Elon Musk.

NoteThe source confirms the campaign name, date (March 2023), the 6-month moratorium request, and the GPT-4 threshold. However, the signature count in the source is 31,810, which is below the claimed '33,000+'. This is a minor discrepancy but within reasonable variance for a living document (signatures may have been added after the claim's 'as of 2023-03' date). The source does not provide the full list of signatories in the excerpt, so the specific names (Bengio, Russell, Wozniak, Musk) cannot be verified from this source alone, though media mentions reference Elon Musk's involvement. The claim is substantially accurate but the signature count is slightly lower than claimed.
