Hi, I am the author. For text-to-SVG, check out IconShop [1]. It was the paper that I tried to reproduce results from initially. In the paper, there is a comparison of their approach against using GPT-4 [2].

Using vectorisation tools like potrace, is indeed a much more popular approach, and there are quite a few papers generating fonts this way. The most recent I believe is DualVector [3]. But I tried to approach the problem from another angle.
