Anthropic Adjusts Claude Session Limits During Peaks

Anthropic this week adjusted how Claude's five-hour session limits are enforced during peak hours, the company announced. The service now counts token usage rather than clock time between 05:00–11:00 PT (13:00–19:00 GMT), so a five-hour allowance can be consumed faster during high demand while weekly caps remain unchanged. About 7% of users—especially Pro subscribers—may hit limits sooner; API customers are unaffected.
Key Points
- 1Enforces session limits by token usage during peak hours (05:00–11:00 PT), not clock time.
- 2Increases token costs at peak times, causing five-hour allowances to deplete more quickly for users.
- 3Recommend shifting token-heavy background jobs to off-peak windows to avoid unexpected session blocks.
Scoring Rationale
Official, timely operational change with measurable user impact; limited by company-specific scope and undisclosed token thresholds.
