But according to Anthropic they are getting the healthy margin right now. If they raise margin it would be “even better”, not just “finally making any money”

But it's not clear that's sustainable. If you look at what happened in the first half of the year, they were very clearly ahead and that translated into both massive growth and great margins. But that looks like it's atleast slowed or maybe even reversed in Q3. And again, that's while there's a shortage of compute and so everyone who has compute can charge a premium for it. Shoot forward 1-2 years as this massive glut of compute hits the market, can Anthropic sustain their margins or do they have to compete with Meta and Alphabet dumping almost free inference to claw back costs on data centre investment.

Depends if the vibe changes, right now people are switching based on capability and not cost (unless it's entirely unreasonable like release Fable).

If we start to see the main switching factor be cost or a plateau in capability then I would be worried.
