The Takeaway

LottieGPT tokenizes Lottie JSON directly, allowing for autoregressive generation of native vector files. This is a massive leap from raster video, providing resolution-independent, editable assets for professional motion design workflows.

From the abstract

Despite rapid progress in video generation, existing models are incapable of producing vector animation, a dominant and highly expressive form of multimedia on the Internet. Vector animations offer resolution-independence, compactness, semantic structure, and editable parametric motion representations, yet current generative models operate exclusively in raster space and thus cannot synthesize them. Meanwhile, recent advances in large multimodal models demonstrate strong capabilities in generati
