Community screenshot (provided by the maintainer, 2026-10-03): one Claude Code /usage session of claude-opus-5-5 with in 23.0k / out 3.0m / cache read 1.3b / cache write 5.6m (CC shows $366.96) = 19% of the weekly quota (all models), Fable weekly 0%; claude-max5x-opus55-round1-2026-10-03.json

15.769B→18.334B (2026-10-03: direct measurement replaces the value derived as 20x÷2, low→medium, Anthropic tier): segment worth $364.89 (read 1.3B×$0.2 + 1h write 5.6M×$8 + in 0.023M×$4 + out 3.0M×$20, priced at the actual write tier) ÷19% ×4 weeks = monthly $7681.94 ÷ Anthropic-tier blended price $0.419/MTok; the community screenshot's origin is unconfirmed and whether all of the 19% belongs to this session is unknown — if there was other usage that week, Opus took fewer pp and the weekly pool is larger, so this value is conservative; 19% is an integer reading, 18.5~19.5% gives 17.864B~18.829B; 1.3b has only two significant figures (±0.05b ≈ ±3.7%); the screenshot shows a 1h TTL and the CC price of $366.96 closes at 1h writes; cache write at the 5m $5 price gives 17.49B, kept for comparison; raw-total basis 27.55B kept for comparison; haiku-4-5 ($0.06) not counted; tension: with the 20x weekly pool = 5x×2, 20x would be about 36.668B, 16% above the 20x adopted value 31.538B — 20x is unchanged for now, and 5x/20x are no longer the same price or merged into one point

X @MiaAI_lab tweet (screenshot provided by the maintainer): xHigh burned 1.0305B raw in 1h2m = ~75% of the 5h limit; claude-opus55-round1-2026-09-23.json; round10 item #15 Max 20x ≈5.5 full windows/week (claude-adoption-round10-2026-09-25.json); Claude Pro × Opus 5.5 adopted sample (issue #52 + Reddit segment) ×10; claude-opus55-max20x-round2-2026-09-30.json

30.17B→31.538B (2026-09-30 decision, Anthropic tier): each path converted to Max 20x weekly-quota percentage points, then merged per pp — (i) the MiaAI window worth $471.10 (write at 5m; closes against the tweet's $482.63) = 75% of a window ÷ 5.5 windows/week = 13.636 weekly pp, 32.981B alone; (ii) the Pro × Opus 5.5 merged worth $628.00 / 196.333 Pro pp ÷ Max 20x weekly quota = Pro×10 → 19.633 weekly pp, 30.536B alone; the two paths differ by 8%. Not adopted: Pro 5h/week 13.333% (7.5 windows) applied directly to Max 20x gives 44.97B (Max 20x windows 20×, week 10× — the window/week ratio differs from Pro's); the official-multiplier derivation with 3.75 windows/week gives 22.49B (the MiaAI window is only 15.5× a Pro window, not 20× — inconsistent with both multipliers at once); equal-weight mean 31.758B; the #65 mixed sample not yet handled. Original 301.7 decision text — new 30.17B: 5h pool 1.0305B÷~75% = 1.374B raw (the 9/22 release had already raised Pro/Max/Team 5h caps, so the window pool reflects release-period basis); implied weight 7.15/13.74 = 0.5204×Opus5 → monthly pool 157÷0.5204; the list-price blend ratio 0.5143 independently corroborates (alternative 30.528B differs by 1.2%); the sample closes at the new price $471.1≈tweet $482.63 (+2.4%); n=1 tweet with no panel, ~75% rounded reading (monthly interval about 28.3B~32.2B), effort only affects rate; if official weights deviate from the price ratio (Fable 6.5× precedent) it must be re-derived; direct weekly-pool panel measurement or post-reset controlled saturation could raise it to high

Both high and xhigh show about $3.2 list dollars per 1%; effort only affects rate. Corroboration (recorded only, not weighted — 2026-09-30 decision closing PR #77): X @kanzakichiya ccusage two weeks 478.15M raw = 22%+47% of weeks (verbal), cache writes all 1h, worth at actual write prices $208.25 → $3.018/pp → 2.881B, within <7% of #52's $3.210/pp and the Reddit segment's $3.036/pp; the three sources merged per pp give 3.009B, and 2.452B with writes at 5m — neither adopted (claude-adoption-round11-2026-09-30.json).

X @leo114119 post (screenshot provided by maintainer): third-party relay usage stats for a Claude Team "6.25x" seat; 7-day window Opus 5.5 total 4,091,470,718 raw (12,836 requests; cache-read hits 4.029B / cache create-writes 49239K / new inputs 26K / outputs 13416K, hit 98.8%); poster claims the week was fully used; panel total cost $1,320.3794; https://claude.com/pricing (Premium seat $125/mo monthly, $100/mo annual); claude-team-opus55-round1-2026-10-06.json

Tier: claude.com/pricing (verified 2026-10-08) Premium seat $125/mo monthly, $100/mo annual; official text says 5x a Standard seat's usage, and the Standard seat only says "more than Pro" with no specific multiplier (the multiplier is counted per 5-hour session); "6.25x Pro" is a community inference via Standard~=1.25x Pro, not an official figure; listed at the monthly-pay price $125. Self-consistency (by weekly list-worth, adopted*$0.419/4): this week $1,320.38 = 4.13x Pro's Opus 5.5 weekly $319.91 and 69% of Max 5x's directly measured weekly $1,920.49; if Premium were truly 6.25x Pro the monthly allowance would be about 19.088B and this value is only 66% of that; the draft's "poster says ~=Max 5x, 4~8% off" compared Team raw against a converted Max 5x figure, a unit mismatch, discarded. Weaknesses -> low: n=1 post; "fully used" is the poster's own claim and the panel shows no quota percentage; the third-party relay panel is not the official /usage and the seat is shared by the organizer; the 7-day rolling window is not aligned with the official weekly reset; whether the official seat pool shares weights with Pro/Max is unproven; 34% below the 6.25x Pro claim. The Team Standard seat ($20/yr or $25/mo) has no quota sample and is not plotted

X @xuanwo post (2026-10-05, screenshots relayed by maintainer): all Other Models usage on Cursor Ultra this billing cycle went to claude-opus-5-5-high; usage-events CSV export covering 9/14–10/5 has 176 Opus records (mostly 22:35 on 10/2 through 14:14 on the 5th, Beijing time); cursor-opus55-community-round1-2026-10-05.json

New 896M (first measured point of the Other Models pool): segment worth $375.46 (read 748.78M×$0.2 + write 24.36M×$5(5m) + in 9.4K×$4 + out 5.19M×$20, hit 96.85%) = all Other Models usage in the cycle ÷ Anthropic-tier blended price $0.419/MTok; raw basis 778M kept as control; 1h-cache-write-$8 sensitivity worth $448.54 (1.071B) not adopted; worth is the same magnitude as the community-cited Ultra Other Models pool $400 (93.9%; CellCog once showed $500) — treated as the monthly pool essentially exhausted; the CSV has no billing-boundary or % fields so the whole export is counted, and if the pool was not fully used this value is conservative; a separate monthly pool from Cursor Models (grok-4.6 7.737B), not linked; single community source, panel % not screenshotted → medium; all records at high effort, which only affects burn rate
