Canva Research unveils Brush vision-language model for design editing

Developed by Canva’s 160-person research organisation from an open-weight foundation model post-trained with reinforcement learning on designer-curated layout and typography rewards, Brush focuses on modifying finished or in-progress designs rather than generating flat images from scratch. When selected inside the Canva AI model menu, Brush inspects the active document, writes and executes code to adjust targeted text, colours, spacing, or visual effects, and visually verifies the updated canvas while keeping untouched layers intact.

Across internal multi-page presentation, poster, and social-asset editing benchmarks, Canva reports sharp drops in both turnaround latency and inference cost compared with its previous general-purpose design agent architecture. Brush is rolling out in beta inside Canva AI for Canva Pro subscribers; Canva has not announced enterprise API access or open-weight plans.
