Estimated from Claude Max 5x
We have not run on Claude Max 20x itself: the figures scale the Claude Max 5x measurement by Anthropic's weekly multiples (Claude Max 5x holds 0.5x the weekly allowance of Claude Max 20x; the advertised 5x and 20x describe the session window), per claude.com/pricing retrieved 2026-09-01. Estimates, never measured numbers. Figures marked est are re-expressed for Claude Max 20x the way the leaderboard's budget picker does it; the underlying runs are on the Claude Fable 5.1, Claude Opus 5.5, Claude Sonnet 5.5, Claude Haiku 4.5 scorecards.

Approx. cost is the listed monthly price spread over the work a month of the plan's usage windows fits at the measured share, per task; the plan bills a flat month, not per task. Tasks a week multiplies the passes the weekly limit holds by the 19 tasks in a pass; a meter that read under 1% gives a floor, not a figure.
What 5x and 20x actually buy
Anthropic sells Max 5x at $100/month and Max 20x at $200/month as 5x and 20x the Pro allowance, so the step from 5x to 20x is advertised as 4x. That multiple describes the 5-hour session window. The weekly limit, the one the leaderboard reads every Claude row on, grows only about 2x from Max 5x to Max 20x, which is the multiple our Max 5x estimates scale by.
Anthropic sells Max as 5x/20x the Pro allowance; our own paired 5x/20x runs measured ~5.7x where 4x is advertised, so the multiple can be well off. That gap was measured on our paired Max 5x and Max 20x runs of the same models on the real-world suite (v3) in August 2026, and the leaderboard repeats it under every budget view.
