How to stop hitting the usage limit by Wednesday

Claude shows you. Open Settings, then Usage. The page is headed Plan usage limits and has two bars: Current session, which is your five-hour window and the time left in it, and Weekly limits, which shows when the week resets, for all models, and separately for the heaviest model if your plan includes one. In Claude Code the same numbers come from typing /usage.

ChatGPT does not have a usage page like this; it tells you when you reach a cap for a model and when it resets, and the cap depends on the plan and the model. So on ChatGPT the method is the same but you fly blind, which makes the habits below matter more.

Three things decide how fast the bar moves, and Anthropic lists them on its usage page: model choice, effort level and current conversation length. The heaviest model uses the weekly budget several times faster than the standard one. A long chat costs more with every message, because the whole conversation is sent again each time. And files you paste in cost every time you paste them.

So the person who hits the limit on Wednesday is usually using the heavy model, in one long chat, pasting the same document in repeatedly. Each of those has a fix.

Anthropic's own advice for using less is "use projects for anything you'll reference multiple times". The reason is caching: content in a project is cached, so the model does not re-read it in full on every message. Content you paste into a chat is read in full every time. The same brief, pasted five times, costs five times.

Make a project per piece of work, put the brief and the reference files in it, and start every chat there. It also fixes the lost-the-plot problem, which we cover in its own guide.

Anthropic's list of tips reads like an editor's: combine related questions into one message, give clear detailed instructions, review your message before sending so you need fewer follow-ups, and refer back to earlier information instead of repeating it. Each round trip resends the conversation, so five small questions cost far more than one message with five numbered questions.

The prompt below is my template. It is boring, and it roughly halves the number of messages I send.

Anthropic's page has one detail most people miss: caches expire after a period of inactivity, and when you come back after a long break the content counts in full again. So an hour of focused work costs less than the same work spread over a day in ten-minute visits.

And when a chat gets long, hand off and start a new one. Every message in a long chat resends the whole history. A fresh chat with a 300-word handoff note is cheaper and gets better answers. In Claude Code, /compact does the summary for you.
