Claude fable 5.1 and opus struggle significantly with generating clean svg vector code compared to gpt-6 astra. → struggles with coordinate accuracy, path closing, and spatial positioning → outputs deformed geometry, broken viewBox framing, and misaligned layers → loses to astra on complex vector math and raw xml generation → shows claude models still lack strong visual-spatial reasoning in raw code → pushes builders toward dedicated design tools over pure code-generated svgs
