Need Help: Keep hitting my rate limit

Hey guys, just started taking the n8n masterclass. I'm trying to do the test workflow (Customer Orders) from the video. My API key is set up and it looks as though it should work...but I keep hitting the rate limit whenever I do a test step with the OpenAI node.

I tried adding $10 to my openAI account. Apparently I'm on the free tier and need to spend $5 to get to the next tier and increase my rate limit. But how am I supposd to spend that $5 if I keep exceeding my rate limit?

I'm trying to burn through my $5 of tokens with OpenAI playground, but it's slow going. This is driving me crazy, what should I do?

Screenshot attached, error details below:
