Fable 5 Returns — Anthropic's Banned Model Is Now Available Worldwide Again

🚫 What Happened? — The Two-Week Ban

In mid-June 2026, Anthropic released Fable 5 — its latest and most powerful AI model. However, just days after release, researchers discovered a serious jailbreak vulnerability that allowed users to bypass the model's built-in safety guardrails.

The U.S. government under the Trump administration temporarily restricted exports of Fable 5 — invoking regulations typically reserved for dual-use technologies.
