GPU memory scales linearly with model count, and VRAM is the limiting resource. Solution : Tensor deduplication automatically identifies and shares bit-identical weight tensors across models, requiring no checkpoint modifications. Results : Across… ## [Shared Backbones: Loading Weights Once, Serving Many Models](https://nitingupta.dev/post/shared-backbones/) _2025-11-29 · ngupta@nitingupta.dev (Nitin Gupta) · Nitin Gupta_ I keep running into the same pattern when trying to self-host models (which is a lot of fun): we run several big models side by side, all of them valuable, all of them slightly different, and all of them wasting VRAM by reloading nearly the same weights. This post is my attempt to explore a specific idea: Can we load a shared backbone of weights once on a GPU, then load only the small,…
