I created an OpenAI pricing calculator on Uniqalc

If you need a quick way to estimate OpenAI costs, I made a calculator on Uniqalc based on the current pricing tables. It lets you input usage and see the projected cost, in case anyone else found this useful.

Also there's a shared calc that has a bunch of models like Claude, xAI etc.
