gpt-5 given 36 days
OpenAI sets retirement for December 11, 2026
Announced as the big one. Fifteen months later, it is on the list like everybody else.
gpt-5, an OpenAI model that answered questions, wrote emails and was blamed for both, has been given a date: December 11, 2026. That is 36 days from this edition. It is 1 year and 2 months old. Until then it will keep answering, as if nothing happened.
Its work passes to gpt-5.6-sol, which the family describes as 'recommended'.
