📝 Walkthrough

Walkthrough

Seedance 2.0 Mini was added to the shared model mapping and exposed as a selectable model in the TextToVideo, FirstLastFrame, and Reference node schemas. The tooltip text for those nodes was updated to mention the Mini tier. Pricing badge expressions were updated for TextToVideo and FirstLastFrame with Mini-specific resolution-based pricing, and Reference pricing was updated with Mini-aware no-video and video pricing plus a different minimum video factor.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Use lowercase match for Mini in JSONata branches.

At Line 1670, Line 1811, and Line 2087/2091/2100, $contains($m, "Mini") likely never matches because widgets.model is lowercased before JSONata evaluation. That causes Mini to fall through to non-Mini pricing/min-factor logic and shows incorrect price badges.

Proposed fix

-                  $pricePer1K := $contains($m, "Mini") ? ($res = "720p" ? 0.005291 : 0.00572) :
+                  $pricePer1K := $contains($m, "mini") ? ($res = "720p" ? 0.005291 : 0.00572) :
...
-                  $pricePer1K := $contains($m, "Mini") ? ($res = "720p" ? 0.005291 : 0.00572) :
+                  $pricePer1K := $contains($m, "mini") ? ($res = "720p" ? 0.005291 : 0.00572) :
...
-                  $noVideoPricePer1K := $contains($m, "Mini") ? ($res = "720p" ? 0.005291 : 0.00572) :
+                  $noVideoPricePer1K := $contains($m, "mini") ? ($res = "720p" ? 0.005291 : 0.00572) :
...
-                  $videoPricePer1K := $contains($m, "Mini") ? 0.002717 :
+                  $videoPricePer1K := $contains($m, "mini") ? 0.002717 :
...
-                  $minVideoFactor := $contains($m, "Mini") ? (3 + $dur) : $ceil($dur * 5 / 3);
+                  $minVideoFactor := $contains($m, "mini") ? (3 + $dur) : $ceil($dur * 5 / 3);

Based on learnings: in comfy_api_nodes/, PriceBadge JSONata widget values are auto-lowercased by the frontend, so checks should use lowercase forms.
