>stable diffusion is an excellent example, the price to train today's or yesterday's frontier is the analogy,

Dont use llms to draft your responses to people, extermely cringe. That explains the llm induced Dunning Krueger.

What examples... There are no public numbers regarding how much it costs to train a 10T model, atleast nothing concrete.

You should just use common sense and think about how you have to fit tensors in memory to train, and the larger the model is the more GPUs you need. Then you could also use common sense to think about how GPUs have gone up in price, not down.
