If o3 is based on GPT-4o, there is a reasoning model based on GPT-4.5 that’s better. If o3 is based on GPT-4.5 (and so the reason it’s still not out is that they are waiting for Blackwells to inference it at a reasonable speed and cost), then it was a hasty job just after the base model for GPT-4.5 was pretrained, and so by now they have something much better. Either way, there is some sort of “o4”, but it’s probably a bad look to announce it before releasing the already-announced o3.
It’s been more than three months since o3 and still no o4, despite OpenAI researchers’ promises.
Deep Learning has officially hit a wall. Schedule the funeral.
