Very cool idea! One question, how much is this costing you out of pocket to host this? The OpenAI GPT4 part must be not nothing.
Currently it's about:
* Rendering the screenshot (urlbox): $0.02
* GPT-4V 1K input tokens = $0.01
* GPT-4V 1K output tokens = $0.03
* GPT-4V Vision pricing (per image size): $0.008
Total: 6.8 cents per a single audit
May not seem like much, but I see a lot of traffic coming from HN, so say 10K people use it, it'll cost $680...
This Hacker News post could have cost $1,000+ if the API rate limit hadn't kicked in. Oh well, silver linings...
Since almost no one could use the app (too many people, and not enough quota from OpenAI), I added a $1.99 one-time payment per audit. This would probably decrease the number of users and also help cover the insanely high costs.
