Official, quoted as official
Anthropic’s pricing page, help-center articles (usage and length limits, the Pro and Max plan pages, usage credits, Claude Code on Pro and Max, API rate limits) and its product announcements. When a statement comes from these, we say so and link to it.
In-product wording
The messages Claude shows when a limit is reached, and the Settings → Usage screen. These are the most accurate signal for any individual account and we always point readers there first.
Approximate figures, labelled as approximate
Message counts such as “around 45 per five hours on Pro” and “at least 225 / 900 on Max” come from Anthropic’s help-center articles on Pro and Max usage. They are approximations written for short messages on a light model, and they predate the 2026 limit changes, so we present them as guidance, explain what makes the real number go up or down, and never as guarantees.
What we do not do
We do not describe workarounds that break Anthropic’s terms, such as multiple accounts, and we do not speculate about internal quotas we cannot verify.
