Claude said "you've reached your usage limit"?
You're mid-prompt. Claude says wait 4 hours. Maybe 5. Maybe until next Tuesday. That's the subscription model working as designed — for Anthropic, not you.
Why subscription plans hit caps
Claude Pro is $20/mo. Claude Max is $100–$200/mo. Those are flat monthly prices. But each Claude call uses real GPU compute — some prompts burn 100× more than others. To not go bankrupt on power users, Anthropic has to cap everyone.
aiusage inverts the model: you pay for credits (GPU-seconds of Claude compute). No monthly fee. No cap. Use a little, use a lot — it's your compute to spend. Credits never expire.
The switch takes 60 seconds

Common questions
"My Claude Pro just reset 2 hours ago — why am I already capped?"
During peak hours (5–11am PT weekdays), Anthropic's new policy burns your 5-hour window faster. A single Sonnet or Opus message can take 20–100% of your session. If you were on aiusage, no session windows exist.
"Is Claude Max worth it?"
Max ($100/mo) gives 5× Pro headroom. Max 20× ($200/mo) gives 20×. Users still hit weekly caps. aiusage's $50 pack gives you 120 runs (≈ Max-level usage) with no reset, no cap.
"Does Claude Code work with aiusage?"
Yes — set ANTHROPIC_BASE_URL=https://aiusage.ai in your ~/.claude/settings.json under env. Same workflow, no rate caps. More on Claude Code setup →
"Can I keep my Anthropic account?"
Yes. Your key stays yours. You can switch back anytime — or use both.
