OpenAI sets retirement for April 1, 2027
gpt-5.1, an OpenAI model that answered questions, wrote emails and was blamed for both, has been given a date: April 1, 2027. That is 147 days from this edition. Until then it will keep answering, as if nothing happened.
It is survived by gpt-6-sol, who is already doing the job.
