The world needs a way to pay for thin AI wrappers without having to turn them into subscription services. There are lots of potential applications where an indie developer can add value on top of LLM's, but can't subsidize GPT-4 usage for the world. OpenAI still doesn't approve of stored bring-your-own-key solutions, nor allow monitoring-and-approval of API costs at the individual consumer level (the new project keys are a step in that direction). The GPT store covers some use cases, and hopefully will get both monetization and a way to expose non-chat interfaces. But until then, everyone with a solution that needs to pass through API costs has to make pricing decisions inconvenient to everyone (in this case, asking too high a price; in other cases, risking overuse or having to heavily restrict usage).
