The record

The Claude Fable 5 timeline

Launch, ban, and comeback: every dated event in the strangest month any frontier model has had, each with a primary source and our own coverage.

  1. Fable 5 launches

    Anthropic releases Claude Fable 5 (claude-fable-5, $10 in / $50 out per MTok) alongside the restricted Claude Mythos 5 — the first Mythos-class models. Fable goes to everyone; Mythos goes only to Project Glasswing partners. Subscribers are told Fable is free on paid claude.ai plans through June 22.

  2. Suspended worldwide by an export-control directive

    Three days in, Amazon researchers report a jailbreak that got Fable 5 to flag software vulnerabilities and write exploit-demonstration code. A US government export-control directive follows, requiring Anthropic to restrict foreign nationals' access. Because no real-time nationality verification exists, Anthropic pulls both models for all users, worldwide — the bluntest instrument available, applied to everyone.

  3. Anthropic disputes the finding

    Anthropic pushes back: the reported jailbreak is narrow, not universal. The company notes that Opus 4.8, GPT-5.5, Kimi K2.7 and other frontier models could identify the same vulnerabilities — and that every model it tested could produce the same demonstration. The implication: singling out Fable 5 punished the model that got reported, not the capability.

  4. The original free window would have ended

    On paper, this is the day the launch promise — Fable 5 free on paid claude.ai plans through June 22 — expired and the credit gate began. In practice it was moot: subscribers had gotten roughly three usable days out of the promised fourteen before the June 12 pullback. The date matters later, when the return terms reopen the argument.

  5. Mythos 5 restored for US organizations

    The US government approves restoring Claude Mythos 5 — for US organizations only. It's the first crack in the wall, and the first signal that the negotiations between Anthropic and the administration are moving. Broader domestic and international expansion is slated for later, under Project Glasswing.

  6. The return telegraphed — then Commerce lifts the controls

    Reports land that Fable access will be restored within days. Then, on June 30, the Commerce Department formally lifts the export controls on both models. Its letter cites Anthropic's coordination commitments — four of them: pre-release access for designated government partners, rapid jailbreak investigation and notification, dedicated research resources on government priorities, and shared voluntary industry standards. Co-founder Tom Brown, not Dario Amodei, led the negotiations. The same day, Anthropic launches Claude Sonnet 5 at $2/$10 intro pricing.

  7. Fable 5 returns globally — with a classifier, and a backlash

    Fable 5 is restored worldwide: the Claude API, claude.ai, Claude Code, and Claude Cowork, with AWS, Google Cloud, and Microsoft Foundry re-enabling it in waves. The model id is unchanged, so configs that kept claude-fable-5 simply start working again. The return ships with a new safety classifier that blocks the reported cyber-jailbreak technique in over 99% of cases — at the admitted cost of false positives on routine coding and debugging, with some tasks handed to Opus 4.8 with a notification. Subscribers immediately push back on the terms: seven days at half of weekly limits, versus the fourteen free days originally promised. Anthropic hasn't directly addressed the complaints.

  8. The included-access window closes

    The return promo window ends: after July 7, Fable 5 on Pro, Max, and Team plans requires usage credits rather than being included in weekly limits. API access and pricing ($10/$50 per MTok) are unaffected. If there's a week to point Fable at your hardest project, this is it — our triage guide says what's worth the rate.

Moral: twenty-two days from launch to ban to comeback — keep the receipts, because the story isn't over.
