Claude Fable 5 built me a live options strategy. It DESTROYED the market out of sample. Then the government banned it.

Claude Fable 5, the strongest finance model ever measured, built a momentum-LEAP options strategy through a public walk-forward runbook. It beat the market by more than ten to one out of sample, and I deployed it live on my $25,000 public account. Three days into the model's life, the US government placed it under export controls and Anthropic took it offline. The full runbook, agent trace, and live book are open.
