Hold on. This makes the whole thing even worse. Anthropic did disclose the weekly limits on its own website in 2025:
Max 5x ($100): 140–280 hours of Sonnet
Max 20x ($200): 240–480 hours of Sonnet
So the $200 plan cost twice as much, but offered only around 1.7x the expected weekly Sonnet usage.
Anthropic has since removed these numbers from the page. Its website now says that “20x” applies per five-hour session, acknowledges a separate weekly limit, but no longer tells customers what that weekly limit actually is.
I fact checked and they really deleted that. wtf
Anthropic used to actually clarify the weekly limits for Claude Max back in July 2025:
Max 5x: 140–280h/week
Max 20x: 240–480h/week (~1.7x more weekly usage than 5x)
then they removed the numbers and never published them again.
so now there’s not even an official estimate for how much more weekly usage you’re actually getting.
