gpt-4-32k, 2023–2025
Retired by OpenAI
It could hold 32,000 tokens in mind at once and cost enough that almost nobody asked it to.
OpenAI has confirmed the retirement of gpt-4-32k, effective June 6, 2025, aged 2 years and 2 months. 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-4o, which the family describes as 'recommended'.
