Kiwi Board-Artist — Nemotron 3 Nano 4B (LoRA)

The whiteboard hand of Kiwi, an AI tutor that draws while it speaks. Given one lesson step (topic, what's already on the board, the sentence being spoken), it emits Kiwi's exact board-op JSON — placing shapes, curves, labels and notes neatly with no overlapping elements.

Fine-tuned with LoRA (r=32, all-linear) for 2 epochs on peekaboo10/kiwi-whiteboard-lessons: 3,553 programmatically constructed gold lesson steps across 8 diagram families and 34 topics, every example validated to render with zero overlaps without post-hoc layout correction. Final eval loss: 0.020940473303198814.
