Abstract: We analyze a model of qubits which we argue has an emergent quantum gravitational description similar to the fermionic Sachdev-Ye-Kitaev (SYK) model. The model we consider is known as the quantum *q*-spin model because it features *q*-local interactions between qubits. It was previously studied as a model of a quantum spin glass, and while we find that the model is glassy for *q=2* , *q=3* , and likely *q=4*, we also find evidence for previously unexpected SYK-like behavior for the quenched free energy down to the lowest temperatures for *q ≥ 5*. This SYK-like physics includes power-law correlation functions and an extensive low temperature entropy, so we refer to the model as \name{}. The model is generic in that it includes all possible *q*-body couplings, lacks most symmetries, and has no spatial structure, so our results can be construed as establishing a certain ubiquity of quantum holography in systems dominated by many-body interactions. Furthermore, we discuss a generalized family of models which includes \name{} and which provably exhibit SYK-like physics in the solvable limit of large local Hilbert space dimension. We also comment on implications of a bosonic system with SYK-like properties for the study of holography, Hamiltonian complexity, and related topics.
