The pause letter
More than a thousand researchers and entrepreneurs called for a six-month halt to training models more powerful than GPT-4.
Why it matters
A significant part of the field publicly asked it to slow down for the first time, and nothing stopped.
Signatories included Bengio, Russell and Wozniak. The argument: development is outpacing understanding of the consequences, and competition stops anyone pausing alone. No pause happened; no laboratory stopped training. The letter's significance is not its outcome but that the argument about pace moved from professional circles into public view within a week of GPT-4.
