What is the difference between Claude Pro and Max? The core difference is actually the amount of usage. Anthropic's official help is clearly written: the Max plan has two tiers, each offering higher usage per session than Pro; And the number of messages is not fixed, it is affected by the message length, attachment size, current session length, and features used. The limit at the Session level resets every 5 hours. The official link is About Claude's Max Plan Usage, and the Pro plan instructions are available in About Claude Pro usage.
Why do you feel that the quota is falling so fast?
Because Claude doesn't just look at how many messages you send, it also counts how many attachments there are in each message, how long the session is, and whether you're using heavier features. A very long conversation with several large documents is usually more expensive than a dozen short questions and answers.
More stable usage
- Try to combine related issues in the same round.
- Start a new conversation on a new topic, don't drag it out in one thread for too long.
- Large attachments are dismantled and small first, and then uploaded.
If you're a heavy user, here's the value of Max: instead of letting you chat indefinitely, it gives you a higher session margin for people who really use Claude as a work tool.
