  AGNs and GRBs produce powerful relativistic jets and their central engines
share the same basic astrophysical ingredients, despite the vastly different
mass scales. Using Fermi and Swift observations, we find evidence that the jets
produced by blazars and GRBs follow the same correlation between the gamma-ray
luminosity and kinetic power. This result suggests that jet production and
energy dissipation mechanisms are remarkably similar over 10 orders of
magnitude in jet power, establishing a physical analogy between AGN and GRBs.
We discuss the implications of these results and the road ahead.
