Briefings
The authors present Compo, a poster generation model that replaces text prompts with a spatial canvas interface. Compo supports four binding types: semantic, identity, text, and pixel, allowing users to compose generation intent directly in space. The model was trained using a scalable pipeline that automatically constructs supervision data for different binding types and their combinations, enabling efficient adaptation without training from scratch. Experiments show Compo achieves stronger compositional controllability than general-purpose image generation models and dedicated poster generation systems while maintaining high visual quality.
Key points
- Compo is a poster generation model that replaces text prompts with a spatial canvas interface.
- Compo supports four binding types: semantic, identity, text, and pixel, allowing direct composition of generation intent in space.
Context
Poster generation traditionally relies on text prompts, which require users to encode two-dimensional composition intent into a one-dimensional sequence of words. This work introduces Compo, a model adapted from a pretrained image editing model to understand Spatial Canvas inputs and Text Specifications, shifting the paradigm from prompting to composing.
Limitations
The evidence is limited to the authors' experimental results on Compo and its training pipeline. Specific performance metrics for other models or the benchmark's detailed results are not provided. The study does not report long-term usability or real-world adoption data.
