GPT 5.6 Uses Sub-Agents to Build Design Tools
dkundel · x · 2026-07-12
A reposted thread showcases a case of building a frontend design tool using GPT 5.6 Sol Ultra: the creator prompted the model to generate an infinite canvas supporting HTML/React design, complete with layers, an inspector, and even real-time collaboration features.
The creator noted that the model essentially wrote it "in one go," primarily relying on planning + sub-agents. Although it consumed a significant amount of credits, there were very few errors overall, and the design aesthetics exceeded expectations, requiring minimal subsequent revisions.
