Meta chief AI officer Alexandr Wang said on X that Muse Wonder and Muse Wonder Full have a bug in how usage is counted against Muse Code subscribers' limits. Wang said the behaviour is not intended, that Meta is working on a fix, and that it will update subscribers once fixed and issue resets.

The bug matters because Wonder Full is only available through Muse Code, whose paid tiers start at $50 a month. Subscribers whose quota drained faster than expected should not assume the usage was real until Meta's fix and resets land.

No timeline for the fix was given in the initial report, which came via TheFly. Watch for Meta's promised update post before drawing conclusions about final quota balances.
