Anthropic Cuts Claude Power in Peak Hours

🔑 Enhanced Key Takeaways

• •The peak-hour adjustment is specifically defined as 05:00 – 11:00 PT (13:00 – 19:00 GMT), during which token costs per session are effectively increased, causing users to exhaust their five-hour session allowance faster than in off-peak periods.
• •Anthropic has simultaneously increased capacity during off-peak hours to compensate for the tighter peak-hour restrictions, ensuring that total weekly usage limits for Free, Pro, and Max subscribers remain unchanged.
• •Internal estimates suggest approximately 7% of users will be impacted by these session limit adjustments, with Pro tier subscribers identified as the group most likely to encounter these new constraints.

🛠️ Technical Deep Dive

• •Session limits are calculated based on token consumption rather than absolute clock time, accounting for conversation length, complexity, and model-specific overhead.
• •Agentic tools like Claude Code exhibit distinct consumption patterns, where recursive API calls and accumulated context history (e.g., 200k+ input tokens per request) lead to rapid depletion of session quotas.
• •The system architecture utilizes a rolling window for usage tracking, where long-running threads become exponentially more expensive as the full conversation history is reprocessed with each new interaction.
