A leaker discovered code strings in Claude Code version 2.1.190 on Tuesday suggesting Anthropic is preparing to restore its Fable 5 AI model with weekly usage limits bundled into subscription plans. The leaker, using the handle 'synthwavedd' on X, posted that the new version includes the string 'You've used your Fable 5 usage for this week,' indicating a shift from the previous separate add-on pricing model. This development follows the Trump administration's June 12 emergency ban on Fable 5 over alleged jailbreak vulnerabilities, which Anthropic disputed while complying with the directive. The leaked strings were independently verified by Decrypt through direct examination of the macOS binary package downloaded from npm.
Decrypt Verifies Leaked Code Strings in Claude Code Binary
Decrypt downloaded the macOS Apple Silicon Claude Code package directly from npm using npm pack @anthropic-ai/claude-code-darwin-arm64@2.1.190, extracted the tarball, and ran strings -a on the bundled package/claude executable. The verification confirmed the presence of new Fable 5 copy: 'You've used your included Fable 5 usage for this week. Continuing on Fable 5 uses usage credits.'
The leaker noted that the phrase 'purchased separately from your plan' appears to have been dropped from the relevant UI copy. The strings do not appear in the public GitHub changelog, but exist in the binary.
Some users noted Amazon Bedrock still shows mentions of Claude Fable 5 on its models. A user going by 'BridgeMind' on X posted that the page is live and the model is listed as sold by Anthropic.
Trump Administration Banned Fable 5 on June 12
Fable 5, the first of Anthropic's Mythos-class models made publicly available, was pulled on June 12 after the Trump administration issued an emergency export control directive citing a jailbreak vulnerability. Anthropic complied but disputed the severity of the finding, arguing that any model currently on the market could replicate the same vulnerability without needing a bypass.
Fable 5 was initially available to subscribers for a limited free window, then was supposed to be moved to usage credits sold separately. The Trump administration banned the model days after its release, alleging it could be a national threat if jailbroken.
The model's status page at status.claude.com still shows the June 13 suspension as active, with no restoration date announced.
Tom Brown Replaces Amodei in White House Negotiations
Anthropic CEO Dario Amodei was seated across a large oval table from Trump at the G7 summit in France, with OpenAI CEO Sam Altman at the president's side and Amodei next to French President Emmanuel Macron. Anthropic refused to allow the Pentagon to use its AI in certain warfare-related applications, a stance that led to it being labeled a supply-chain risk. Trump has accused Anthropic of being 'woke.'
Per Wired, Anthropic swapped out Dario Amodei for cofounder Tom Brown as its point person in White House discussions about Fable 5's return. The administration has reportedly been happier since Brown took the lead.
Brown had been in meetings with Commerce Secretary Howard Lutnick and National Cyber Director Sean Cairncross since mid-June. The negotiations center on building a shared framework for evaluating AI jailbreak incidents.
Trump said last week that he no longer views Anthropic as a national security threat, walking back a position he held as recently as mid-June. Anthropic responded with a statement thanking the administration for its 'ongoing partnership.'
