When enrolled in an [OpenAI / ChatGPT plan](https://chatgpt.com/pricing/)
(e.g. Pro/Plus), you may want to figure out how much weekly usage (%) you have
left.
I’m sure codex has an
/usage
or /cost
command to do so, but what if I’m using a third-party harness like Head over to https://chatgpt.com/#settings/Usage to assess your usage limits.
Usage limits normally reset every week.
You can buy API credits (and even enable auto reload) when you run out, just like how you would do with your mobile phone plan.
Alternatively: codexbar. — § —
