Is the NIST AI RMF mandatory?

No. The NIST AI Risk Management Framework is a voluntary, outcome-based framework. The EU AI Act, by contrast, is binding law with financial penalties.

Does following NIST AI RMF make me EU AI Act compliant?

Not on its own. NIST is a strong governance foundation and much of its evidence is reusable, but the EU AI Act adds specific binding obligations - transparency labelling, GPAI documentation, conformity assessment - that NIST does not require.

Can one governance program cover both NIST and the EU AI Act?

Yes. Both share risk-management primitives, so a single mapped control set with crosswalked evidence can satisfy NIST outcomes and EU AI Act obligations together.
