There's still some glitches, occasionally the entire app code would get replaced by the function the LLM was trying to update. I could fix it by telling it that's what had happened, and it would then fill everything in again... Waiting for the entire app to be rewritten each time was a bit annoying.
It got the initial concepts of the app very very quickly running, but then struggled with some CSS stuff, saying it would try a different approach, or apologising for missing things repeatedly...and eventually it told me it would try more radical approaches and wrote online styles... I wonder if the single file approach has limitations in that respect.
Very interesting, very fun to play with.
I'm kind of concerned for security things with LLM written apps - you can ask it to do things and it says yes, without really thinking if it's a good idea or not.
But cool!
And anything which helps with the internet to be full of small independent quirky creative ideas, the better.
