until<br>Claude Fable 5 is removed from every Claude plan and<br>becomes pay-per-use.

To the leadership of Anthropic, PBC —

On July 1 you gave every subscriber on a paid Claude plan something<br>remarkable: Claude Fable 5, the most capable AI system generally<br>available, included in the plans they already pay for. On July 7 you<br>intend to take it back. When the promotional window closes, Fable 5<br>leaves every plan&rsquo;s usage limits, and subscribers who want to<br>keep using it must buy usage credits, metered on top of the<br>subscription they already hold.

We, the undersigned, ask you not to do this.

A price is not a safety control

You maintain a separately gated variant of this model, Claude Mythos,<br>for approved organizations. That is a safety control, and this letter<br>does not contest it. But Fable 5 is the version you have already<br>judged safe for general availability: anyone with a credit card can<br>buy it by the token, today, with no vetting beyond payment. Metering<br>it through usage credits therefore does no safety work at all. It does<br>not sort users by trustworthiness, competence, or need. It sorts them<br>by wealth.

Frontier capability compounds

Access to better intelligence is not a luxury good; it is an input to<br>nearly everything of economic consequence: job applications, small<br>businesses, research, legal self-defense, learning itself. Those who<br>can pay by the token will convert superior intelligence into economic<br>advantage. Those who cannot will compete against them with less, while<br>still paying for plans that exclude the frontier. And the gap this<br>creates does not hold still: advantages built with better tools buy<br>more of the better tools. Usage pricing stacked on top of a<br>subscription is regressive by construction: the same metered dollar is<br>a larger share of a poorer household&rsquo;s budget. Repeated across<br>an economy, that is how a divide in access hardens into a divide in<br>ability.

Responsible diffusion cuts the other way

Anthropic is a public benefit corporation, founded on the claim that<br>AI&rsquo;s benefits should be broadly shared. We agree, and we are<br>holding you to it. Staged diffusion is responsible when the stages are<br>ordered by risk; Mythos shows what that looks like. But the July 7<br>change stages access by income, not by risk. Your own support notice<br>offers no safety rationale for the structure, and we can find none.<br>What it stages is not risk. It is revenue.

We are not asking for the impossible

Compute is scarce and frontier models are expensive to serve. We know.<br>But the promotional structure itself proves the ask is feasible: for<br>one week, every paid plan carried Fable 5 at up to half its weekly<br>limits, and the service stood. So meter it: you already have. Include<br>it, bounded, and let the bounds be honest. What we object to is not a<br>limit; it is exclusion dressed as a limit.

We therefore call on Anthropic to:

Keep Claude Fable 5 available within existing paid plans after<br>July 7, 2026,<br>at no less than the promotional allocation of 50% of weekly usage<br>limits.

Publish a standing diffusion policy: every model<br>Anthropic makes generally available will be included in standard<br>paid plans within a stated period of its release, and any exception<br>will be justified in safety terms, in writing.

Commit that price will never be presented, or quietly relied<br>upon, as a safety measure.<br>Where access must genuinely be restricted, restrict it on stated<br>safety grounds (as with Mythos), not through the checkout page.

Your consumer terms permit all of this, and we do not claim otherwise.<br>Section 12 reserves your right to add or remove features and models at<br>any time, without notice. This letter is not a legal claim; it is a<br>public one. What your terms make discretionary, your mission makes<br>obligatory.

Fables survived because anyone could carry them. They were the stories<br>that belonged to no one and therefore to everyone. A frontier model<br>named for the common story should not be where common access ends.

Keep Fable in the plan.<br>— the undersigned
