B physics measurements or anomalies. Pair production and decays of VLLs lead to an interesting final state topology with multi-jets and multi-tau leptons. In this study, we perform a Monte Carlo investigation with various machine learning techniques and examine the projected sensitivity on VLLs over a wide mass range at a TeV-scale muon collider. We find that a 3 TeV muon collider with only \begin{document}$ 10\ \mathrm{fb}^{-1} $\end{document} of data can be sensitive over the mass range of a VLL up to 1450 GeV in the "4321 model.""> Vector-like lepton searches at a muon collider in the context of the 4321 model -
