Claude Peak Time Starts "Speed Limiting": About 7% of Users Affected, Pro Subscription Most Impacted

According to 1M AI News, Anthropic's Claude Code team engineer Thariq Shihipar announced on X that, in response to Claude's continued usage growth, Anthropic is adjusting the session quota allocation for the Free, Pro, and Max subscription tiers during peak hours. The users' total weekly quota remains unchanged, but during weekdays from 5 a.m. to 11 a.m. Pacific Time (with the U.S. having entered daylight saving time, corresponding to 8 p.m. to 2 a.m. Beijing time), the 5-hour session quota will be depleted faster.

Shihipar stated that the team has implemented significant efficiency optimizations to mitigate the impact, but about 7% of users will now encounter session limits that were previously not encountered, with Pro subscribers being particularly affected. He recommended users running high token-consuming background tasks to reschedule them to off-peak hours to extend their available quota and mentioned that efforts to expand capacity will continue.
