Claude Fable 5.1 plans and real prices
Real price = monthly fee ÷ tokens you can actually use in a month. “vs API” shows how many times cheaper than the official API list price (standard workload mix) the plan is. “Evidence” opens the full calculation and sources for that row.

Maintainer-provided sample: same-day Max account /usage weekly quota 0%→19% corresponding to 2,443 turns and 285.6M raw tokens (cache read 283M + output 2.6M); claude-fable51-round3-2026-09-20.json; round9 timeline correction
3.006B→1.728B: the sample was measured during the 9/4~5 promo period — the 19% denominator is the promo pool 4.72B/week, not the permanent pool 3.925B — the old algorithm wrongly attached the blended equivalent pool to the permanent basis and did not split Opus's share; re-decomposed: consumption 0.19×47.2 = 897M equivalent, Opus share 113M raw weight 1, Fable share 172.5M raw → implied weight ≈4.54× Opus (lands inside Fable 5's measured 4.25~6.5 interval, self-consistent); monthly quota = 157×50%÷4.54; the dollar-weighting method independently verifies at 1.70B; the next day's 3,017 turns → 24% cross-checks (same-period basis consistent); single account n=1 → medium; not workload-normalized: the sample has only cache read + output, lacking write/input components, and was decomposed through a promo-period pool
