o3-2025-04-16 given 36 days
OpenAI sets retirement for December 11, 2026
o3-2025-04-16, 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 6 months old. It continues to work normally in the meantime, which is the strange part.
Its work passes to gpt-5.6-sol, which the family describes as 'recommended'.
