It is not clear at all if Claude will actually be profitable, are there enough people who will actually pay the subsidized costs especially if they end up being a significant fraction of an additional dev's salary.
The challenge all these frontier labs have is: Their existing models can have high token profitability, but they have to invest everything they've got (and everything they're given) into new model R&D, because if they don't xAI will beat them, or Anthropic will beat them, or Google will. That's the nature of frontier spaces like this.
But the flipside is, model capability will plateau, they probably are already, and as that happens it becomes safer to aim for profitability. And I have zero doubt that OpenAI and Anthropic can find profitability. xAI, Perplexity, Mistral, and the other labs, I'm less sure about.
