Does training of new models go into RnD or cost? And subscription plans' subsidies, are those cost or sales and marketing?
Pretty likely R&D, but obviously would need to be confirmed by OpenAI.
The original reporting includes this:
> The documents revealed how much OpenAI paid Microsoft for services. In the 2025 calendar year, OpenAI paid Microsoft $10.59 billion for “Research and development” expenses. We believe this most likely refers to the cost of training OpenAI’s models.
Given the enormous cost of training, would it be worth training new models then?
I'm not an expert, but is this even an option? I mean models must be refreshed with latest knowldge base periodically even without algo/design improvements, otherwise the lag become too noticeable and it will hurt users and their use-case.
