OpenAI Codex will undergo a usage reset today, Day 17, taking effect before 10 a.m. Pacific Time, according to Codex head Tibo. Tibo also urged users to apply for Daybreak Blue access in advance, noting the application takes about 15 minutes and should not be left until a security incident occurs. Daybreak is OpenAI's Trusted Access for Cyber program, with Daybreak Blue serving as one of its access tiers.
