I am having a similar issue. My usage page is showing me the wrong value for the tokens I’ve used.
I have been using the GPT-3.5-Turbo endpoint for testing.
My usage reflects a higher rate than the $0.002 per 1k tokens documented in the API.
I have used 749 tokens this period and it reflect a $0.21 usage amount, which =/= the rate for GPT-3.5-Turbo as documented.
We are not the only ones experiencing these issues, see Reddit: https://www.reddit.com/r/OpenAI/comments/11h7f8r/openai_is_charging_10_x_for_api_usage/
Hopefully the reason your page isn’t updating has to do with a fix.
