hence the generous free tier. You want it to be big enough for a team of developers to do all the experimentation and development work, and also to launch a product to a small audience.

As soon as your product is a success, you run out of free tier, and you will have to negotiate a price with the sales team.

If I were OpenAI, then while I had a market leading product, the price would be 'I want half the profit margin of whatever you're using it for'.
