Our verdict
Choose Claude Max 5x for one person running a few agents. Both plans include Opus 5.5 and Fable, so the extra $100 changes headroom rather than capability.
Choose Max 20x when many agents need to run at once. The 20x applies to the 5-hour window. The weekly limit is only about twice Max 5x.
$100 gives Opus 5.5 five times the Pro allowance. Opus 5.5 is light enough on the limit to keep several agents running through the day. Fable is included for the hardest planning, but Opus 5.5 now covers most of it. Move here when the Pro limit stops you.
Pros
Five times the Pro allowance
Room for several Opus 5.5 agents
Sonnet 5.5 for smaller things and simple tasks
Fable for the hardest planning
Cons
Pro covers most single-agent days for $80 less
Best for People who keep hitting the Claude Pro limit. Start on Pro first.
How far it goes: at least 15 times a week, and more than 100 for the cheapest model
Our whole real-world issues and spec planning pass runs at least 15 times a week, and more than 100 for the cheapest model on this plan, depending on which model you run.
That works out at about under 23c to $1.84 of the subscription per run, at the list price.
Measured on this plan, at <1% to 8%/1w of its allowance per run. A share belongs to the plan it was measured on, so we never subtract one plan's from another's.
$200 is the largest Claude allowance, with Opus 5.5 and Fable through Claude Code, the best CLI agent. That is room for many agents running all day. Opus 5.5 does most of the work. Fable is there for the hardest planning. Buy it only if the Max 5x limit is blocking your work.
Pros
The largest Claude allowance
Many Opus 5.5 agents all day
Sonnet 5.5 for smaller things and simple tasks
Fable for the hardest planning
Cons
Max 5x covers most days for $100 less
Best for People who keep hitting the Max 5x limit. Start on a cheaper plan first.
