gpt-5.3-codex given 147 days
OpenAI sets retirement for April 1, 2027
gpt-5.3-codex, an OpenAI model that wrote code that other people then took credit for, has been given a date: April 1, 2027. That is 147 days from this edition. Visiting hours are open: it still answers every request until that day.
Its work passes to gpt-6-sol, which the family describes as 'recommended'.
