# Compare Two Models

This is the last step in the Get Started arc - loading a second model revision alongside the one you've been exploring, and reading your first diff.

## Steps

1.  From the command palette, run **Compare With…** and choose a second checkpoint - ideally a different revision or fine-tune of the model you already have open, so the comparison is meaningful.
2.  Tensormorph aligns the two checkpoints (matching tensors by name and shape) and sets your original model as the **baseline**.
3.  Switch to the **Diff** view - the comparison-mode counterpart to the Architecture view you already know from [Explore a Model Architecture](/docs/get-started/explore-a-model-architecture). Regions that differ are shaded using Tensormorph's diverging color convention: cyan where the candidate increased relative to baseline, red where it decreased, dark where nothing changed.
4.  Select the same tensor you inspected in [Inspect a Tensor](/docs/get-started/inspect-a-tensor). Switch to the [Matrix and Heatmap view](/docs/editors/matrix-and-heatmap-editor)'s **Diff** shading mode for a precise, cell-level read of exactly how that tensor changed.
5.  Open the [Scalar Inspector](/docs/editors/scalar-inspector) on a changed cell - it now shows both revisions' values side by side, not just one.

If you can see a shaded diff in the Diff view and read one specific changed value in both revisions side by side, you've completed your first comparison - the same workflow behind reviewing a fine-tune, a quantization pass, or a merge proposal.

## Where this goes next

Everything in this tutorial arc - navigating, inspecting, comparing - is the foundation for the rest of Tensormorph's workflows: [diffing at scale](/docs/compare-and-morph/weight-diff), [resolving a merge conflict](/docs/compare-and-morph/merge-conflicts), or [tracing a runtime pass](/docs/profiling/runtime-traces) all build directly on these same navigation and inspection patterns, just applied to a more specific question.
