OpenAI model switched off after 2 years and 10 months
OpenAI has confirmed the retirement of gpt-3.5-turbo-1106, effective September 28, 2026, aged 2 years and 10 months. It answered questions, wrote emails and was blamed for both. Code that still calls it will find out the hard way.
It is survived by gpt-5.6-terra, who is already doing the job.
