The temporary 50% bump to weekly limits runs out September 13, replaced the next day by a permanent 25% increase over the standard cap. Testing Catalog puts the net drop at roughly 17% against what subscribers have right now.
Anthropic posted the change from its Bluesky account, covering Pro, Max, Team, and seat-based Enterprise plans. The 50% boost had been extended through August 31, with Anthropic saying at the time that it hoped to make an increase permanent.
