Everything is still based on 4 4o still right? is a new model training just too expensive? They can consult deepseek team maybe for cost constrained new models.

Where did you get that from? Cutoff date says august 2025. Looks like a newly pretrained model

If the pretraining rumors are true, they're probably using continued pretraining on the older weights. Right?

> This stands in sharp contrast to rivals: OpenAI’s leading researchers have not completed a successful full-scale pre-training run that was broadly deployed for a new frontier model since GPT-4o in May 2024, highlighting the significant technical hurdle that Google’s TPU fleet has managed to overcome.

It's also plainly obvious from using it. The "Broadly deployed" qualifier is presumably referring to 4.5
