Clarification (verified with sources):
What people are calling a “bug” is actually an intentional change Google rolled out in late 2025: the system moved from a single 5-hour reset to two simultaneous limits — a 250-unit sprint resetting every 5 hours, plus a 2,800-unit weekly baseline. Both must be positive to keep working. If you exhaust the weekly limit on day 1, on day 6 you still have 24 hours left in the cycle — of course it’s still locked even if you “didn’t use anything that day.” The 5-hour timer keeps resetting, but it’s irrelevant if the weekly pool is empty. Most reported “bugs” are simply this misunderstanding. Google never explained it clearly.

Key survival tips: never use Opus for everyday tasks — it burns 8x more quota than Sonnet and ~800x more than Gemini Flash. For daily work, Sonnet on fast mode with pinned context gives 40-80 active hours per week. Critical insight: Claude and Gemini run on completely separate quota pools — if Claude locks, Gemini Flash remains your escape hatch.
