Summary

Claude Fable 5.2, Anthropic’s most capable generally available model for technical work, is now on AWS via Amazon Bedrock and Claude Platform.
It can run unattended for hours‑days, coordinate sub‑agents, and targets software engineering, scientific research, and quantitative finance; Claude Mythos 5.2 retains cyber/bio capabilities for verification programs.
Fable 5.2 is a covered model requiring data retention, but zero‑retention use is allowed until Enterprise Frontier Safeguards are available; see AWS docs for details.
