Just got an email about OpenAI winding down fine-tuning?
OpenAI is winding down the fine-tuning API and platform. Existing active customers can continue running fine-tuning training jobs through [January 6, 2027](calendar:T2:January 6, 2027), after which creating new training jobs will no longer be possible.
And
Inference on fine-tuned models will only be turned off once the underlying base model is deprecated.
Maybe this is a way to save money but it kind of hurts the main appeal of using OpenAI services in my opinion.
