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+'. While 31,810 could potentially have grown to 33,000+ by the end of March 2023 (the claim specifies 'as of 2023-03'), the source shows 31,810 as the current count at publication (22 March). The claim of 33,000+ signatories is not confirmed by the source text provided. Additionally, the source excerpt does not display the full list of signatories, so the specific names mentioned (Yoshua Bengio, Stuart Russell, Steve Wozniak, Elon Musk) cannot be verified from this source text alone, though media mentions at the bottom reference Elon Musk. This is a partial confirmation due to the signature count discrepancy and inability to verify all named signatories from the provided excerpt.
