“You've reached your weekly limit. Resets Thursday at 9am.”

What it means

The weekly bar for your plan (all models, or Opus only) is full.

When it resets

7 days after the weekly window started.

What to do now

1. If only the Opus bar is full, switch to Sonnet with /model.
2. Shorten context: /compact or start a new session.
3. Consider Max 5× or 20× if this happens every week.
