gpt-4.5-preview, 2025–2025
Retired by OpenAI
Very large, very expensive, and gone almost before anyone could afford to get to know it.
gpt-4.5-preview, an OpenAI model that answered questions, wrote emails and was blamed for both, was switched off on July 14, 2025, aged 4 months. Requests addressed to it are expected to come back unanswered.
Its work passes to gpt-4.1, which the family describes as 'recommended'.
