ComfyUI Node
DiffusionGemma Trace
Post-hoc analysis over a complete canvas_trace. Renders a heatmap IMAGE plus a STRING summary (avalanche/commit curve + mask-token corroboration verdict). mode selects the heatmap signal: commit (which positions changed per step) or entropy (per-position predictive entropy, normalized per render). cell_px upscales the raw steps×positions grid so it's readable.

Inputs (3)
| Name | Type | Default | Description |
|---|---|---|---|
| canvas_trace | DGEMMA_CANVAS_TRACE | A complete per-step trace from a sampler-class node. | |
| cell_px | INT | 61–32 | Nearest-neighbor upscale factor for the heatmap (a raw steps×positions grid is unreadably small). |
| mode | COMBO | commit | Heatmap signal: commit = which positions changed each step; entropy = per-position predictive entropy (normalized per render). |
