OpenAI Updates Preparedness Framework After Safety Lead's Public Exit

OpenAI released an updated Preparedness Framework offering more focused risk identification, stronger mitigation requirements, and greater transparency in how it evaluates and governs AI safety. The update follows the resignation of David Robinson, who led drafting of the original framework and oversaw safety reports on 12 frontier model launches before quitting the week of September 28, 2026. Robinson published an essay in The Atlantic titled 'I Quit OpenAI Because Its Culture Is Broken,' arguing that OpenAI's 'unimpeded optimism' created a dangerous environment and that frontier labs still operate like perpetual startups when their increasingly capable systems require the layered redundancy and failure planning of nuclear plants or aviation.
