OpenAI model switched off after 2 years and 11 months
OpenAI has confirmed the retirement of gpt-4-1106-preview, effective October 23, 2026, aged 2 years and 11 months. It answered questions, wrote emails and was blamed for both. Code that still calls it will find out the hard way.
Survived by gpt-5.6-sol, younger, cheaper, and named in the same documentation table.
