Create an OpenAI API Key

Blazebar needs an API key to talk to OpenAI models (GPT-4o, o1, etc.). This takes about 2 minutes. You'll need an OpenAI account.

Heads up: OpenAI's API is pay-as-you-go. You'll need to add a payment method and load a small credit balance ($5 minimum) before your key will work. New accounts may get free trial credits.
