Qwen3.5-9B fine-tuned to generate a self-contained React JSX widget from a
target screenshot and deterministic dimension, OCR, and palette context.
This is a full-weight BF16 checkpoint, not a PEFT adapter. The vision tower was
frozen during SFT; the language policy was trained for two epochs on 1,816
paired image-code examples from
Djanghao/Widget2Code-Data.
The model emits code that must be executed in a sandboxed renderer. It can
produce invalid or unsafe code and should not be executed in a privileged
environment.
In the stored 1,000-image Widget2Code test run, generation completed for 957
examples and 924 outputs rendered successfully. Mean SSIM among rendered
outputs was 0.7247. The run used temperature 0.7, repetition penalty 1.1, and a
10,000-token limit.
These numbers describe the stored evaluation run and are not a claim of
general-purpose frontend correctness.
