Architecture Editor
This page is titled "Architecture Editor" to match its address in the workbench, but Tensormorph's own View menu calls it the Architecture view - one of eight 3D views (alongside Layer Stack, Tensor Volume, MoE Expert Galaxy, Parameter Map, Diff, Morph, and Runtime Flow). "Editor" and "view" refer to the same panel throughout this documentation.
The Architecture view is Tensormorph's default 3D view: a spatial rendering of a model's structure, from the whole-model overview down to an individual layer or module, that you navigate rather than read as a list. It follows the same region layout as every other view in the workbench, specialized here for structural navigation.
Regions
Header region
The header runs along the top of the view and is split into three groups, left to right:
Navigation menus
- View - camera presets (front/top/isometric), frame-selected (
F), frame-whole-model (Home), and a projection toggle (orthographic vs. perspective). - Select - selection operators: by type, by link (e.g. "select linked experts"), box/lasso select. Selection here stays in sync with the Outliner.
- Switch view (
1/2/3) - jump to a 3D, 2D, or 1D view of the current selection without losing it.
Snapping
- Toggles snapping to the address grid (see Snapping to the address grid).
Display
- Shading mode - magnitude-heatmap, sparsity-mask, or gradient-flow shading of the visible tensors.
- Overlays - the toggleable annotation layer (shape labels, stride markers, quantization-boundary lines); see The overlay system.
- Isolate (
/) / Hide (H) - narrow the view to the current selection, or hide it, without changing what's actually selected in the Outliner.
Toolbar region
A vertical strip of active tools, following an active-tool model: whichever tool is selected changes what a click or drag does, until you switch tools again. The default set includes Select, Measure (read out shape or distance between two points on the address grid), and Probe (inspect a scalar under the cursor without changing the current selection). Weight editing and interpolation tools live in the dedicated Morph view, not here - the Architecture view only ever renders derived statistics, so nothing done in it can alter a weight.
Inspector panel
A collapsible panel on the right edge showing properties of the active selection and of the view itself - the always-available, view-local counterpart to the full Scalar Inspector. Unlike the Scalar Inspector, it never leaves the Architecture view, so it's the fastest way to check a shape or dtype without switching views.
Snapping to the address grid
Snapping in the Architecture view targets the address grid - a coordinate system derived from the Semantic Model Graph's address space, not an arbitrary user-configurable spacing. Selecting a tile snaps to the tile boundary; selecting a layer snaps to the layer boundary. This keeps two structurally different models comparable in the same space: their grids align at every level of the hierarchy even when their shapes differ.
The overlay system
Overlays are independent, toggleable annotation layers drawn on top of whatever shading mode is active - they never require switching shading modes to see them. The default overlays are:
| Overlay | Shows |
|---|---|
| Shape labels | Tensor shape at each node, always legible regardless of zoom |
| Stride markers | Where a tensor is a view rather than a contiguous copy |
| Quantization boundaries | Where dtype or quantization scheme changes across a module |
| Address grid | The coordinate scaffold described above |
Toggle overlays from the header's Overlays popover.
Performance at scale
Shading modes are not free - magnitude-heatmap and gradient-flow shading cost more to compute per frame than a flat structural view, and that cost is most visible at trillion-parameter scale where most of the model is off-screen or far from the camera. Because the Architecture view only ever renders mergeable tile statistics (moments, min/max, norms, NaN/Inf counts) rather than raw parameters, distant or coarse-detail structure can be shaded from cheaper, coarser statistics automatically - see Level of Detail and Streaming.
