 - Merge models in minutes instead of hours on low VRAM. For a 3060/3060 Ti user: This script enables functionality that is otherwise impossible (merging 70B models or large 7B merges with `--cuda`) without OOM. [More details here](https://huggingface.co/spaces/Naphula/model_tools/blob/main/mergekit_low-VRAM-graph_patch.md)
 - Update: v18 is much faster than v4 and replaces the trial-and-error loop with an adaptive math-based calculator (using GrimJim's measure.py logic)
