I don't expect any of the third party openrouter providers sell tokens at a loss. Agreed that increasing model size could drive token prices up however so far there's been a very strong trend in the opposite direction with smaller models becoming increasingly capable thanks to advances in theory and implementation.
Edit: A glaring omission on my part there is that growth of aggregate industry demand for tokens has the potential to outpace increases in supply provided by new datacenters buildouts. So tokens certainly could go up depending on how things play out.
