Ryan Greenblatt, one of the modelers behind the AI 2027 forecast, publicly corrected an error: the software R&D acceleration multiplier from recursive self-improvement should be 3.8x, not the previously stated 4.5x. He noted the corrected timeline still corresponds to March 2027 in the AI 2027 scenario, and apologized for the mistake.
