​
nodes
object[]
required
​
edges
object[]
required
​
modelPresets
object

Canvas-wide default model + variant the user configured in canvas settings, per category (image/video/text/audio). When a node is created with no modelConfig, the server pins these defaults exactly. Use this to know what model+mode will apply, so you can pick correct edge handles and avoid hallucinating the default
