  In this note, we leverage the author's pasting theorem for
$(\infty,n)$-categories to construct new models of $(\infty,n)$-categories for
all $n \leq \infty$, as presheaves on certain categories of computads. Among
these new models are some which facilitate a construction of the Gray tensor
product of $(\infty,n)$-categories Day convolution and reflection, which we
carry out here. After constructing this Gray tensor product of
$(\infty,n)$-categories, we characterize it via several model-independent
universal properties.
