$0.13/prompt can only be useful for artists/end users. Anyone thinking about using this at scale would need a 20/30x reduction in price. But there's still no API available so I think that will change with time. Maybe they will add different tiers based on volume.
That is a fair point. I don't think the pricing is unreasonable, but it feels limiting. You could try 1000 variations until you find what you need perfectly, but in that pricing model users will be induced to use less the tool, not more.
I'd prefer an option to pay like 200 usd/year to use unlimited. And maybe have a price per use only in the API.
edit: this pricing model also makes it expensive to learn to use the tool.
Until you consider the level of demand for this product, which is surely higher than OpenAI can scale to with the number of GPUs they have. If they price it lower they’ll be overwhelmed.
