Claude Code Rate Limits Are Burning Out in Minutes -- Anthropic Adjusts Peak-Hour Caps to Manage Demand

TL;DR: Claude Code users began reporting on March 23 that their 5-hour session limits were being exhausted in 1-2 hours -- or even on a single prompt for some Max 20x subscribers. Anthropic's Thariq Shihipar confirmed this is intentional: 'To manage growing demand for Claude, we're adjusting our 5-hour session limits for free/Pro/Max subs during peak hours (5am-11am PT on weekdays).' During those windows, a session burns compute faster, meaning users get fewer tokens per session hour. The change follows a similar rate-limit reset just a month earlier tied to a prompt caching bug.

Why it matters: Anthropic throttling its flagship coding agent mid-session -- without proactive user notice -- reveals the scale mismatch between Claude's soaring demand and available compute. For paying Max subscribers, this directly degrades the product they're paying $100-$200/month for. It's a leading indicator of the infrastructure pressure Anthropic faces as Claude Code adoption accelerates.
