Anthropic
Claude Fable 5
v5 · frontier · Released June 9, 2026
Updated July 29, 2026
The U.S. government has partially reversed its prior export control suspension on Claude Fable 5 for foreign nationals, though the model remains under restricted access conditions. A full suspension was in effect due to a jailbreak finding, and the partial reversal does not clear all constraints.
Enterprise guidance
Fable 5 has been reinstated following a US government-directed suspension. Before restoring Fable 5 to production, complete a vendor risk reassessment covering: (1) contingency protocols for future government-directed suspensions, (2) export control classification monitoring for your user base, and (3) agentic deployment boundary controls. Document the June 12 suspension as an AI governance incident. Confirm your access tier status with your Anthropic account team before redeployment.

Status history
July 29, 2026· yellow to yellow
Development IvmpKIE9WBSO4XUOXmmd confirms a government-forced suspension due to a jailbreak finding, which alone justifies RED. However, development Ls1HQrjj2LxgesTKyj7l reports a partial reversal of that suspension, reducing but not eliminating the government access restriction. The model still meets YELLOW criteria given the ongoing partial government-imposed access control and the unresolved jailbreak concern. No escalation to RED is warranted given the reversal, and no downgrade to GREEN is appropriate while restrictions persist.
July 1, 2026· red to yellow
Fable 5 reinstated following US government review. Suspension lifted but export control history and vendor risk gaps warrant Use with Caution per governance assessment.
July 2, 2026· red to red
Fable 5 is already designated RED. The new development explicitly confirms an active export-control directive suspending access for foreign nationals, which is consistent with and further substantiates the current RED classification.
June 12, 2026· green to red
US Commerce Department export control directive suspended all access.
