OpenAI may not be training GPT-5, but Sam didn't say anything about GPT-4.5.

In fact Greg Brockman explicitly said they are considering changing the release schedule in a way that could be interpreted as opening the door for a different versioning scheme.

And actually there is no law or anything that says that any particular change or improvement to the model or even new training run that necessities them calling it version 5. It's not like there is a Version Release Police that evaluates all of the version numbers and puts people in jail if they don't adhere to some specific consistent scheme.
