OpenAI schedules model shutdowns through January 2027, phasing out fine-tuning

By PulseAugur Editorial · [1 sources] ·

OpenAI has announced a series of model deprecations and shutdown dates extending until January 2027. Several older models, including GPT-3.5 Turbo, GPT-4, and GPT-4 Turbo, are scheduled for shutdown on October 23, 2026. Newer models like GPT-4o and GPT-4o mini will follow on January 14, 2027, with GPT-6 Luna slated as the replacement for many of these. The company is also phasing out its fine-tuning platform, with new fine-tuning jobs ending on January 6, 2027, and existing fine-tuned models adhering to the shutdown schedule of their base models.

IMPACT Developers must update their code to migrate from deprecated OpenAI models and endpoints before the scheduled shutdown dates.
