We study four-point functions in Chern-Simons vector models in the large $N$limit. We compute the four-point function of the scalar primary to all ordersin the `t Hooft coupling $\lambda=N/k$ in $U(N)_k$ Chern-Simons theory coupledto a fundamental fermion, in both the critical and non-critical theory, for aparticular case of the external momenta. These theories cover the entire3-parameter "quasi-boson" and 2-parameter "quasi-fermion" families of3-dimensional quantum field theories with a slightly-broken higher spinsymmetry. Our results are consistent with the celebrated bosonization duality,as we explicitly verify by calculating four-point functions in the freecritical and non-critical bosonic theories.
