FAQ

Why do I keep hitting usage limits in Claude Code?

Claude plans reset on a rolling 5-hour window with weekly caps on paid plans, and Claude Code shares one pool with Claude chat. Long contexts and Opus-class models burn the pool fastest.

Is a subscription or the API cheaper for coding agents?

It depends on volume. Use the calculator: if your API estimate for the model you use is above a plan's price and that plan's quota covers your work, the plan wins.
