OpenAI to sunset self-serve fine-tuning platform by January 2027

By PulseAugur Editorial · [1 sources] ·

Customers using fine-tuned versions of models like GPT-4o and its variants must migrate their custom models before this date. The company advises users to audit their current fine-tuned models, collect their training data and test cases, and begin training replacement models on their own infrastructure, as the model weights will remain with OpenAI.
