Anthropic’s paid plans have new names. Max 5x for $100 is now Max, while Max 20x for $200 is Ultra. The subscriptions product lead says the new names should be more informative.

The old numbers referred to usage limits, but not in the same way for every limit. Max 20x had a 20x five-hour limit and a weekly limit set at 10x Pro, which led some new users to read the name incorrectly.

For verified Ultra accounts, the five-hour limit is being removed. Sessions can continue without interruption, with only weekly limits remaining. The change follows complaints about the mismatch between plan names and actual limits.
