Theo, CEO of T3 Code and T3 Chat according to the X profile, posted a chart on 10 November putting a dollar value on Claude’s $200-a-month Ultra plan at Anthropic’s API list prices. Spent only on Opus 5.5, a month of the plan’s limit was worth $14,662 on that account, 73 times the price. Spent only on Fable 5.2, the model Anthropic released on 9 November, it was worth $3,021, or 15 times.
The chart says the figures come from one account and 1.1 million proxied requests between 11 August and 9 November. Fable is capped at half of each weekly limit, and on Theo’s figures that half bought $3,021 of Fable 5.2 against $7,331 of Opus 5.5: about 2.4 times as much API value for Opus, by our arithmetic.
Business Pill · Usage-Based Pricing
An evergreen Business Engineer explainer on usage-based pricing: paying for work, not for seats. It explains the general idea only and does not discuss Claude Ultra or Fable 5.2.
The key insight: Theo, CEO of T3 Code and T3 Chat according to the X profile, posted a chart on 10 November valuing a month of Claude Ultra’s $200 limit at API list prices: $14,662 spent only on Opus 5.5 and $3,021 spent only on Fable 5.2, on one account. Anthropic caps Fable at half of each weekly limit; on Theo’s figures that half bought about 2.4 times as much API value on Opus 5.5, by our arithmetic.
The post reads: “The $200 Claude Ultra plan gets you $15,000 of Opus 5.5 in a month, but only around $3,000 of Fable 5.5”. It adds: “Even ignoring that Fable is restricted to 50% of your weekly limit, it burns faster per $ than Opus does.” The post text says Fable 5.5; the attached chart labels the model Fable 5.2.
The chart, titled “What $200 of Claude Ultra gets you”, lists five ways to spend a 30-day month. Opus 5.5 only comes to $14,662. Using Fable 5.2 first and then Opus 5.5 comes to $10,353, made of $3,021 of Fable 5.2 and $7,331 of Opus 5.5. The same order with Fable 5.1 comes to $9,528. Fable 5.2 alone is $3,021 and Fable 5.1 alone is $2,197.
Its footnote says “One month is 30 days, which is 4.3 weekly limits. One week of only Opus 5.5 is worth $3,421.” The two figures agree: $3,421 times 30 divided by 7 is about $14,661, by our arithmetic. The footer describes the basis as “one account” and “API list prices”.
API list-price value of half of a 30-day month of Claude Ultra’s limit on one account, as posted by Theo (@theo) on 10 November 2026 from 1.1 million proxied requests between 11 August and 9 November; not independently verified. Fable is capped at 50% of the weekly limit, per Anthropic. The 2.4x ratio is our arithmetic.
What Was Posted on X
Fable 5.2 is the best model I’ve ever used. It finds bugs and fixes them that Opus 5.5 just missed. Super impressive, insane model.
But oh boy does it eat through your rates fast, especially 5h limit. Even on medium effort.
User view on usage limits: @kimmonismus posted on 10 November at 08:52 UTC that Fable 5.2 is โthe best model Iโve ever usedโ and finds and fixes bugs that Opus 5.5 โjust missedโ, but added: โoh boy does it eat through your rates fast, especially 5h limit. Even on medium effort.โ This is one userโs experience; the post gives no usage figures.
What Anthropic’s Own Pages Say
Anthropic’s pricing page lists Ultra at $200 a month with “10x Pro usage” every week, no 5-hour limit for verified accounts, and “$200 a month in API credits, up from $100 on Max”. In its plan table, Fable on Max and Ultra is “50% of weekly limits”.
The Help Center article on Ultra says “Ultra plans have a weekly usage limit that applies across all models, and a separate weekly limit for Fable”. It also says “Additional usage limits may apply to manage capacity and ensure fair access to all users”. The article on Fable models says they “draw from your plan’s regular weekly usage limits and use them faster than other Claude models”, and that past the 50% mark users can keep using Fable “with usage credits” or switch models.
None of the Anthropic pages we read gives a dollar value for a plan’s limit or says how much faster Fable uses it. Theo’s chart is a measurement of that from outside, on one account’s traffic.
Update (10 Nov): Anthropic’s Fable launch offers. Anthropic’s Help Center article Claude Fable 5.2 launch offers sets out extra Fable usage for a limited time. Max and Ultra plans, premium Team seats and premium seats on legacy seat-based Enterprise plans get “One to three Fable limit resets, depending on how long you’ve subscribed”: one under six months, two at six to 12 months, three over 12 months, counted from the first paid bill. Those resets expire on 8 March 2027. Pro plans and standard Team seats get “All Fable models included in your plan for one week, up to 50% of your weekly usage limits, plus one Fable limit reset”, through 16 November at 11:59 pm PT. Resets go only to accounts with paid billing in place before 9 November at 10:00 am PT.
A reset “gives you back the usage you’ve spent on Fable models” on the weekly limit and refills a five-hour window where an account has one. Anthropic adds: “A reset doesn’t raise your limits.” The 50% Fable cap stays in place, and the article puts no dollar value on a reset. testingcatalog’s 10 November daily brief on X summarised the offer for Ultra, Team Premium and Pro; Anthropic’s own text also covers Max plans and standard Team seats.
The Price Sheet Behind the Gap
On Anthropic’s API price sheet, Fable 5.2 costs $8 per million input tokens and $40 per million output tokens, twice Opus 5.5’s $4 and $20. Cache hits cost $0.20 per million tokens on both. Our report on the Fable 5.2 launch is in Anthropic Launches Claude Fable 5.2, 20% Cheaper Than 5.1.
As we read Theo’s figures, a higher list price alone would raise the dollar value of each Fable token, not lower it. The chart shows the opposite: the same half of the limit bought about 2.4 times as many API dollars on Opus 5.5 as on Fable 5.2, by our arithmetic, which is what the post means by Fable burning “faster per $”.
As we read it, the chart turns Anthropic’s plain-language line that Fable uses limits faster than other models into a dollar gap, measured on one account rather than published by Anthropic.
As we read it, the subscription and the API now price the same model differently: on the API, Fable 5.2 costs twice Opus 5.5 per token, while inside the plan, on Theo’s figures, each unit of limit returned less than half the API value on Fable.
Anthropic Help Center, Claude Fable models on your plan
“They draw from your plan’s regular weekly usage limits and use them faster than other Claude models.”
Three Implications
FOR ULTRA SUBSCRIBERS Anthropic’s pages say Fable can use up to 50% of the weekly limit, after which users can pay with usage credits or switch models; the plan also includes $200 a month in API credits.
FOR DEVELOPERS COMPARING PLAN AND API Fable 5.2 lists at $8 per million input tokens and $40 per million output tokens, twice Opus 5.5’s $4 and $20, with cache hits at $0.20 on both, on Anthropic’s price sheet.
FOR THE SUBSIDY DEBATE Theo’s Opus 5.5 figure is 73 times the planprice; the guest in the SemiAnalysis clip we reported earlier put a $200 Claude plan at $12,000 of Opus 5, 60 times by our arithmetic.
The framework says: “The subscription is a call option on token deflation.”
As we read it, Theo’s chart shows the size of that option on one account: $14,662 of Opus 5.5 at list prices for a $200 plan. The framework predates Ultra and Fable 5.2 and does not discuss them.
What Is Not Established
The figures are one account’s, reconstructed at API list prices, and we could not check the underlying logs. Subscribers do not pay those prices, so the dollar values describe usage, not what Anthropic spends to serve it. The chart’s window ends on 9 November, the day Fable 5.2 was released, and it does not say how many Fable 5.2 requests the figure rests on. We read Theo’s first post and its chart, not the rest of the thread. Anthropic has not published a dollar value for any plan limit.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
One account’s logs, posted by Theo, put a month of Claude Ultra’s $200 limit at $14,662 of Opus 5.5 or $3,021 of Fable 5.2 at API list prices. Anthropic caps Fable at half of each weekly limit and says Fable uses limits faster; on Theo’s figures, that half bought about 2.4 times as much API value on Opus 5.5 as on Fable 5.2, by our arithmetic.

A note on sourcing. The dollar values of the Ultra plan are Theo’s measurement, posted on X on 10 November 2026 from one account’s requests at API list prices; we did not see the underlying logs. Plan terms, Fable limits and API prices are from Anthropic’s pricing page, Help Center and API price sheet, read on 10 November. The 2.4x ratio and the consistency check are our arithmetic.
