AI coding subscriptions, graded: is each plan worth it?

One page per plan: what it costs, what it buys, how far one pass of our fixed task set goes on it, and whether we would pay for it. Measured plans read straight off the provider's meter on the W40 2026 grading run. Plans we did not run on borrow a sibling plan's measurement, scaled by the provider's own advertised multiple and marked est. Two plans side by side is compare subscriptions; a recommendation is the quiz.

Plan usage is what one pass of our fixed task set (real-world issues plus spec planning, the suites every agent runs alike) consumed of that plan's own allowance, on the best-graded model on the plan. Each figure is a share of a different subscription and never comparable across rows. Estimates scale a sibling plan's measurement by the provider's advertised usage multiple, never by price. 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. Verdicts and prices are the quiz's versioned editorial catalog (v48), last reviewed Oct 1, 2026.
