Claude Max 20x becomes Ultra and drops the 5-hour limit

Anthropic has renamed the top of its consumer plan ladder and loosened the limit that heavy users complain about most.

On October 30, Anthropic’s Claude account announced two changes on X: Max 5x is now simply “Max,” and Max 20x is now “Ultra.” Prices stay the same, at $100 and $200 a month, and existing subscribers move over automatically with nothing to do. The bigger change is that verified Ultra accounts no longer have a five-hour session limit.

What changed

The rollout details reported so far:

• Verified accounts only. Coverage says the limit is gone for verified Ultra accounts. New Ultra accounts reportedly keep a temporary five-hour cap until verification clears. Anthropic is said to tie the verification step to fraud and abuse prevention.
• Most existing subscribers get it first. Anthropic began rolling the change out to most current subscribers the same day.
• Max keeps its session window. The $100 plan keeps a five-hour limit at five times Pro, plus a weekly limit.

What did not change: the weekly cap

This is not unlimited Claude. Ultra still has a weekly allowance reported at ten times Pro, and coverage notes a separate weekly cap on Fable, plus Anthropic’s stated right to add capacity-related limits.

That detail reframes the old name. According to the reporting, the “20x” in Max 20x referred to the five-hour session window, not to weekly capacity. For weekly use, the plan was always about ten times Pro.

The practical effect depends on how you work:

• Occasional heavy sessions. If you open Claude for a couple of intense hours a day, the session limit was the one you hit. Removing it is a real gain.
• All-day, every-day work. If you run Claude Code from morning to night, the weekly cap is the one that binds, and for you the change may be small. One analysis argues Anthropic’s announcement does not say how much extra work the plan provides, and that heavy users who hit the weekly cap gain little.

We found no independent measurements of how much additional usage verified Ultra users actually get, so that remains an open question.

The naming dispute

The rename also lands in the middle of a debate about what the multiples meant. One outlet notes a lawsuit disputing the “20x” figure, and that the new names drop the multiples altogether. That makes plan comparisons harder: “Ultra” no longer tells you how much usage you are paying for. Check Anthropic’s pricing page for the current terms before relying on any figure here.

How this fits the usage-limit story

Limits have been a recurring fault line for AI subscribers. In August, Anthropic cut Claude weekly usage by 17% for Claude Code users, and in July OpenAI briefly removed its five-hour limit for Codex and ChatGPT Work before its pricing documentation listed a shared five-hour window again. Anthropic’s move now removes the session window on its highest consumer plan while keeping a weekly ceiling, a different trade-off from either.

What it means for working professionals

• If you are on Max 20x: nothing to do. Your plan appears as Ultra, and the five-hour limit should lift once your account is verified.
• If you are on Max 5x: your plan is now just Max, with the same five-hour window.
• If you are choosing between tiers: compare on weekly usage, not on the name. The tier that matters is the one whose weekly allowance covers your real workload, and whether you want to work in long, uninterrupted sessions.
• For teams and freelancers billing client work: long unbroken sessions are the main benefit. Plan around the weekly cap, because hitting it mid-week is still possible.
