Fable 6
There is no announced Fable 6 — no name, date, or specs. “5” is the generation: Mythos is the unrestricted frontier tier, Fable the safeguarded public face of the same model, so Fable 6 means a whole new generation. Between here and there sits an analyst-predicted hardened “Fable 5.1” (not Anthropic-confirmed), and any future Mythos-class launch now carries Anthropic’s new commitments — government pre-release testing among them — forged in June’s export-control freeze. The market prices the next Mythos-class drop (whichever it is) at 84% by Sep 30. The second a new generation answers, ArtificialWatch fires.

Fable 5 returns worldwide — with the safeguards that will gate every future launch
Anthropic redeployed Fable 5 globally behind a new safety classifier blocking the reported jailbreak “in over 99% of cases,” and Mythos 5 returned for vetted US organizations. The relaunch came with four forward commitments — including pre-release government evaluation for national-security-relevant models — that now shape how a Fable 6 would ship. via Anthropic · 9to5Google
Export controls lifted — and Sonnet 5 ships the same day
Commerce lifted the directive on Fable 5 and Mythos 5; Anthropic announced the return that evening while also launching Claude Sonnet 5, its cheaper agentic workhorse. The frontier line and the workhorse line now move on separate cadences. via CNBC · Anthropic · TechCrunch
The roadmap read: a hardened “Fable 5.1” likely lands before any Fable 6
An analyst roadmap ranked Anthropic’s likely next moves: restore Fable 5 (done), then a hardened Mythos-class variant “possibly labeled Fable 5.1”, then point-bumps elsewhere — on a ~6–8 week cadence. A prediction, not an Anthropic statement, and this page treats it as one. via AIToolsReview (analyst, unconfirmed)
Generation 5 launches — and gets frozen in 72 hours
Fable 5 and Mythos 5 launched Jun 9 (1M-token context, adaptive thinking) and were suspended Jun 12 under a US export-control directive over a reported jailbreak. The 19-day freeze is chronicled day-by-day on our sister site FableWatch. via Anthropic · FableWatch
