Best known upper bound for Dedekind zeta function on line $sigma=1$ in the $t$ aspect

What’s the best known upper bound for the Dedekind zeta function $zeta_K(s)$ of a number field $K$ for $s=1+it$ as $trightarrow infty$. For example, is something like this
$$zeta_K(1+it)=o(log{t}),$$
known, where we allow $o$ to depend on $K$.
