 ## Cautionary note
 
+**Read this:** using GPT-3 is not free, so any interaction with the GPT-3 model(s) is counted towards you token quota. You can find details about Open AI's pricing model at [https://openai.com/api/pricing/](https://openai.com/api/pricing/).
+
+You receive a reasonable credit for free and do not need to provide any payment information for the first interactions with the model. Once you token quota nears its end, Open AI will let you know. Your usage is tracable in your Open AI account dashboard.
