How we compare
- Sources
- Official plan pages, help docs and public user reports. We don’t test the tools hands-on.
- No single score
- Each provider measures usage in its own units, so we never convert between them.
- API value per $1
- What a full month at the plan’s cap would cost at API list prices, divided by the plan price, shown as a range across dated public reports. A ceiling for people who hit their caps, not typical use. SemiAnalysis’s June test is shown for reference only.
- Usage per $
- Each vendor’s own multipliers, so it only compares plans from the same vendor.
- Sentiment
- A sample of firsthand X posts per coding agent, found and labeled by Grok. Up to 40 posts per agent per day; the count does not measure posting volume. Grok also labels its own Grok Build. See the counted post data. Rates the agent, not the plan. No score under 50 posts.
- Offers
- Checked on each provider’s pricing page, help center, release notes, blog and X account. Active only until the published end date.
- Evidence
- Every value opens its sources. Unmarked values come from official pages; marks flag user reports, our take, third-party estimates and anything we couldn’t verify.
Coverage & evidence gaps9 notes
- No hands-on testing or tasks-per-dollar benchmark. User reports are small samples, not consensus.
- Usage units differ: OpenAI counts messages per five hours, Anthropic multiples of Pro per five-hour and weekly window, SpaceXAI a weekly pool shared with chat.
- API value per $1 comes from a handful of public usage reports. Grok figures are forum estimates with low confidence, and plans without a report show “Not measured”.
- Codex and Grok Build context windows are model figures. Per-plan windows aren’t published.
- Claude Team and ChatGPT Business publish relative usage, not counts. Grok Business gives no amount.
- Enterprise and Edu plans are contact-sales, so they aren’t compared.
- Official X accounts need sign-in, so promo posts there weren’t fully readable.
- Sentiment covers X only, not Reddit, and is a sample. Grok labels xAI’s own Grok Build.
- Availability was checked in public docs, not by signing up.

Author says he hit Claude Pro’s limit by 2pm and moved to the $100 plan, then wrote workaround tactics. Sample of one; no message counts or task detail given for the Pro tier itself.
Author ran Claude Max 20x for six weeks, tracking her own weekly usage meter, then downgraded to Max 5x for several more weeks. Sample of one account; no ccusage or API-cost log shown, only self-reported meter percentages.
Author argues Anthropic’s 20x multiplier applies only to the five-hour session limit, and the separate weekly cap runs closer to twice Max 5x. Secondhand: he relays other users’ reports rather than his own meter. Member-only article; checked through its public preview.
Author on ChatGPT Plus used her entire rolling 5-hour Codex allowance in about 24 minutes on one Find-and-Replace feature, leaving it unfinished. Single session, single task.
Author downgraded his own ChatGPT account from Pro 20x to Pro 5x to help fund a separate SuperGrok Plus subscription, and compares the two months. Sample of one; no message or token counts given, only his own before/after read of workflow speed and wall-hitting.
Author pays for SuperGrok Plus, describes using Grok Bot to build a small analytics team and a news scraper in his first week, then hitting his weekly limit once before an early reset. Sample of one, no independent numbers.
Same author’s own SuperGrok Plus billing screen hit 100% of the weekly pool, then reset early with no published explanation; his separate Grok Chat meter read near zero. Sample of one account’s dashboard, not an independent measurement.
Author on SuperGrok Heavy ran the same three tasks across Grok Build, Claude Code and Codex CLI and reports roughly 10 hours saved in the first week. Sample of one reviewer over one week, not a controlled benchmark.
Issue filed on ChatGPT Plus: one request to open a Flutter app through the Build iOS plugin used 36% of the Plus limit and still failed. One task, one account, with a session ID for OpenAI to check.
Pro 5x user logged raw token counts: on Aug 30, 344.8M tokens used about 30 points of the weekly allowance; on Aug 31, after an automatic reset, 331.6M tokens used about 93 points. One account; the user reports it as a metering bug.
Pro 20x user took a full weekly window from 100% to 0% between Sep 8 15:54 and Sep 9 21:32 on GPT-6 Astra, about 403M raw tokens (about 98% cached input). A full Pro 5x window on another account was about 51M tokens, a ratio of about 7.9×. One user’s logs, posted in an open issue.
Pro 20x user estimates effective capacity at roughly 6–8× Plus, not 20×, from their own Codex token throughput. They say it is an estimate, because the analytics page does not show quota units. The issue, opened Aug 12, is still open.
Claude Pro user says one normal working cycle on Opus used about 50% of the 5-hour Pro limit, and a single plain question on Sonnet used about 9%, in a long multi-day session. One user, reported as a regression.
Max 5x user ran one ultracode review that spawned 18 Opus 5.5 agents and used 70% of the 5-hour session in about 20 minutes, then waited about 5 hours for the reset. One run of a multi-agent feature, not typical single-agent use.
Max 20x user on CLI 2.1.278 logged 9.6B tokens over 7 days, 93.9% on Opus 5, and says 30% of the weekly limit went on day one, which projects exhaustion in about 3.3 days. One heavy account’s own logs.
Weekly Claude Code limits were 50% higher from May 13 through September 13, 2026. From September 14 they are 25% higher than before the promotion on Pro, Max, Team and seat-based Enterprise. Page shows only a relative update date.
Three accounts measured in August 2026, during the +50% weekly-limit promotion, on Opus, Fable 5 and Sonnet 4. Author’s Max 20x: about $3,400–3,900 of API-priced usage per week. Two Max 5x accounts (friends): about $997–1,031 and $1,118–1,167 per week. Article concludes 20x is about 3.5× Max 5x weekly.
Pro 5x ($100) user regressed 20+ pairs of remaining weekly limit against ccusage API-priced spend on GPT-5.6 (non-fast). One weekly limit equalled about $675 on July 13 and about $600 on July 23, an 11% drop. Author says limits may differ by user or be A/B tested.
Pro 20x user extrapolated measured intervals to a full weekly allowance: about $1,925 on GPT-5.6 Sol (Sep 1–4) and about $1,234 on GPT-6 Astra (Sep 8). Interval-based estimates from local token logs, not a full allowance drained; the author says they are not proof the cap was cut.
Pro 20x user recorded about $5,450–5,500 of ccusage API-priced usage over 3.0 to under 3.5 full weekly allowances on mixed models, with Fast mode off and context at 272K or below. Implies about $1,557–1,833 per weekly allowance.
Forum estimates of weekly API-priced value on Grok 4.5 and 4.6. SuperGrok: about $50 per week (one commenter), $100–120, about $90 without the doubled first week, and about $125 after halving a $250 estimate for a doubled first-week quota. SuperGrok Heavy: about $500 per week (one commenter; another disputes it). No published data.
685 sampled firsthand X posts from 665 authors across six complete UTC days, found and labeled by grok-4.7 with X Search. This saved sample was trimmed from the September 23 scan; the partial last day was excluded. Up to 40 posts per product per day were searched, so counts do not measure posting volume. Grok also labels Grok Build. Every counted post link is kept for audit.
