Consistency models (CMs) learn a consistent mapping from multiple noise levels to the data endpoint and can therefore perform generative inference in one or a few steps. This property makes them attractive as learned priors for low-latency inverse problems. Multiple-input multiple-output (MIMO) channel estimation under limited pilot overhead can be formulated as a high-dimensional linear inverse problem with an explicit measurement matrix, where data consistency alone is often insufficient for stable angular-domain channel recovery. This paper applies the plug-and-play consistency model (PnP-CM) framework to pilot-aided MIMO channel estimation. The PnP-CM inference procedure enforces the pilot observation model in the data-consistency update and invokes a pretrained CM denoiser in the prior update, thereby recovering the angular-domain channel vector within a small number of outer iterations. Preliminary experiments validate the feasibility of using CMs as low-latency channel-estimation priors and show that adaptive parameter scheduling and cross-scenario robustness remain important directions for further improvement.
