Hey, this isn’t a bug, it’s working as intended.
The 100% used indicator only shows your Pro plan included quota usage. Your account also has credits, which are a separate pool that automatically covers requests after you run out of included quota. That’s why Claude Opus 4.6 keeps working without errors.
If you look at the usage breakdown for the last few days, you can see some requests are billed to included, and some to credits, mostly claude-4.6-opus-high-thinking.
Agreed the UI could be clearer. Right now it’s not obvious that credits are a separate pool. This feedback about improving the display is already on our radar.
