summary: "Anthropic's internal AI model identified the specific timestamps that generated the seed parameters for the NIST elliptic curves, resolving a 26-year-old cryptographic puzzle in under 30 minutes. The research version of Claude confirmed the findings as real-world after calculating that 20 top bits were clear, which it determined as a one in a million probability."

## Summary

Anthropic's internal AI model identified the specific timestamps that generated the seed parameters for the NIST elliptic curves, resolving a 26\-year\-old cryptographic puzzle in under 30 minutes\. The research version of Claude confirmed the findings as real\-world after calculating that 20 top bits were clear, which it determined as a one in a million probability\.
