“Apple charges 15% but for whatever reason it's really closer to 20% of revenue up to your first million… Beyond that Apple charges 30 but really closer to 33%. People significantly overestimate the cost of AI in the back end — AI costs are sub 3%.”

The scary-sounding bill — OpenAI tokens — is usually under 3% of revenue unless you're generating images or voice. The real cost stack is Apple taking ~20% (and ~33% past the first million) plus marketing and headcount. Plan around the platform tax, not the model tax.
