Infrared dynamics of SYK model (and tensor models with similar large N physics), exhibit some of the non trivial features of near extremal black holes, such as maximal chaos and nearly AdS$_2$ symmetry. In this note we present a class of tensor models that can be thought of as describing probes to such a black hole. Our models are obtained by adding probe fields to SYK like tensor models. Dynamics of the original model in unaffected by the probe fields in large N limit. Further all four point functions exhibit maximal chaos in large N limit, a non trivial feature expected of a black hole probe.
