Advanced LIGO \& Advanced Virgo are detecting a large number of binarystellar origin black hole (BH) mergers. A promising channel for accelerated BHmerger lies in active galactic nucleus (AGN) disks of gas around super-masssiveblack holes. Here we investigate the relative number of compact object mergersin AGN disk models, including BH, neutron stars (NS) and white dwarfs, viaMonte Carlo simulations. We find the number of all merger types in the bulkdisk grows $\propto t^{1/3}$ which is driven by the Hill sphere of the moremassive merger component. Median mass ratios of NS-BH mergers in AGN disks are$\tilde{q}=0.07\pm 0.06(0.14\pm 0.07)$ for mass functions (MF) $M^{-1(-2)}$. Ifa fraction $f_{AGN}$ of the observed rate of BH-BH mergers(${\cal}{R}_{BH-BH}$) come from AGN, we expect a rate of NS-BH (NS-NS) mergersfrom the AGN channel of ${\cal}{R}_{BH-NS} \sim f_{AGN}[10,300]\rm{Gpc}^{-3}\rm{yr}^{-1}$,(${\cal}{R}_{NS-NS} \leq f_{AGN}400\rm{Gpc}^{-3} \rm{yr}^{-1}$).Allowing for the ratio of NS-NS/BH-BH LIGO search volumes, from preliminary O3results we can rule out the AGN channel as a dominant contribution to observedNS-NS mergers. The number of lower mass gap events in this channel is a strongfunction of the nuclear MF and mass segregation efficiency. Compact objectmerger ratios derived from LIGO can restrict models of MF, mass segregation andpopulations embedded in AGN disks. The expected number of EM counterparts toNS-BH mergers in AGN disks at $z<1$ is $\sim[30,900]{\rm{yr}}^{-1}(f_{AGN}/0.1)$. EM searches for flaring due to embeddedevents in large AGN surveys will complement LIGO constraints on AGN models andthe embedded populations that must live in them.
