gpt-3.5-turbo-0301, 2023–2024

Retired by OpenAI

gpt-3.5-turbo-0301 passed away on September 13, 2024, aged 1 year and 6 months, by scheduled deprecation, in a data center it never saw. It answered questions, wrote emails and was blamed for both. Code that still calls it will find out the hard way.

Its work passes to gpt-3.5-turbo, which the family describes as 'recommended'.
