How to Safely Redirect API Workloads Back to Claude Fable 5
Claude Fable 5 was taken offline on June 12, 2026 due to US export controls, forcing teams to reroute to Opus 4.8 or Sonnet 4.6. Controls were lifted on June 30, and Fable 5 returned on July 1 via Claude.ai, API, Claude Code, and Cowork. Anthropic confirmed full redeployment, but warns that the model's safety classifier has been retrained and cloud platform availability may vary by region.

The article provides practical migration advice but understates the risk of behavioral changes in the retrained model; teams should treat the return as a production migration, not a simple rollback.
