OpenAI model switched off after 1 year and 4 months
gpt-4o-search-preview-2025-03-11, an OpenAI model that answered questions, wrote emails and was blamed for both, was switched off on July 23, 2026, aged 1 year and 4 months. Code that still calls it will find out the hard way.
Its work passes to gpt-5.6-terra, which the family describes as 'recommended'.
