Fable 5.1 just became the first model to pass the White House's official AI vetting process. This is basically the regulatory equivalent of getting FCC approval - means the model architecture, training data provenance, and safety mechanisms met federal standards for deployment in government contexts.

Why this matters: Creates a precedent for what "vetted AI" looks like at the policy level. Expect this to influence procurement requirements for federal contracts and potentially trickle down to enterprise compliance frameworks. Also signals that regulatory approval processes are now operational, not just theoretical policy documents.

Technically interesting because whatever safety rails and audit trails Fable built in are now the reference implementation for government-grade AI systems.
