I was frustrated that open ai's playground lacks function calls, so I wrote my own more similar to ChatGpt!
Now I can:
* use the same models I program against
* have access to function calls
* can see how much it's costing me
Side benefit: I can share my API key with a friend so they can use Gpt3.5 & 4 as open ai took their deposit but still labelled their account as free tier - mistakes happen.
Prerequisite: an open ai api key

Use at your own risk as I blindly installed npm packages.
