🚨 Anthropic restores Claude Fable 5 with tighter safety guardrails after a 19-day suspension 🚨
Anthropic restored Claude Fable 5 on July 1, 2026 after a 19-day suspension tied to a jailbreak report and U.S. export controls. The model is back online with a new cybersecurity classifier, broader guardrails, and usage limits for eligible users.
🔑 Key highlights:
🔹️ Claude Fable 5 was restored globally across Claude.ai, Claude Platform, Claude Code, and Claude Cowork.
🔹️ The suspension began after Amazon researchers found a jailbreak technique that bypassed safety guardrails.
🔹️ The U.S. Department of Commerce issued emergency export controls on June 12, which forced Anthropic to block access globally.
🔹️ Anthropic added a real-time cybersecurity classifier that blocks the specific jailbreak technique in more than 99% of cases.
🔹️ Access is limited to Pro, Max, Team, and select Enterprise users, with reduced usage limits from July 1 to July 7.
🔹️ After July 7, usage moves to credits rather than standard subscription allowance.
🔹️ Anthropic and partners including Amazon, Microsoft, and Google are building a broader jailbreak response framework through Project Glasswing.
🎯 Bottom Line: Claude Fable 5 is back, but with stronger guardrails, government-reviewed safeguards, and tighter access controls.
