OpenAI self-serve fine-tuning does not have a researched profile yet. Everything here comes from its recorded changes and public listings, each linked to its source.
From May 7, 2026, organizations that never ran fine-tuning cannot start. From July 2, 2026, organizations without fine-tuned inference in the past 60 days cannot create jobs. On January 6, 2027, all new fine-tuning jobs stop. Inference continues until base models are deprecated.
Takes effect Jan 6, 2027 · in 66 days
