An infinite canvas for designs, nearly one-shotted
Meng To asked GPT-5.6 Sol Ultra for an infinite canvas for HTML and React designs: layers, an inspector, and real-time collaboration. Planning plus sub-agents got most of it in one pass.
An infinite canvas is a product. It needs layers you can reorder, an inspector that talks to real HTML and React, and more than one person in the file at once. Meng To asked GPT-5.6 Sol Ultra for all of that.
The path is the interesting part. Planning plus sub-agents, paced across a session long enough to burn through the usage limits. The author thanks the resets. That is a useful tell: the work was large enough that the model had to be fed in stretches.
A design tool with collaboration is the kind of surface people still picture as a team's job. Here it arrived nearly one-shot.

I asked GPT 5.6 Sol Ultra to build an infinite canvas for HTML/React designs with layers, an inspector, and even real-time collaboration. It pretty much one-shotted the whole thing using planning + sub-agents. It burned through my limits (thanks for the resets!), but holy https://t.co/fBv3rI63nQ
