I did a clean clone. (just FYI - there are some dependency errors - needed to to npm install —force
But the outcome, when running on localhost:3000 is still the same. http://localhost:3000
I get the same when using your deploy direct to Vercel and running it from there. Not sure what the problem is. They OPENAI api key has all the rights needed, I;m Tier 4 user with those models in my playground etc.
Update - I restarted the app today - and it works. I wonder if there was a change on the OpenAI side of things (or in my account). Did not touch the code, keys etc. Cool stuff
