Canva Craft trained on millions of templates and 25,000 designer-evaluated image pairs
jacob_top · reddit · 2026-10-24
A Reddit post examines how Canva trained its Craft model: the company says training drew on millions of human-made templates, with professional designers assessing over 25,000 image pairs during internal evaluation.
The author argues the more interesting lesson for software companies is how they pick which work a model should learn from. Using a hypothetical sales product, he notes that labeling every proposal attached to a won deal as a good example could teach the wrong lesson — the customer may have already trusted the vendor, or a competitor may simply have missed a deadline. Instead, have people who understand the work judge the artifacts themselves: does the proposal accurately describe the customer's problem? Can a buyer follow the value-case assumptions? Such judgments give a more specific basis for selecting examples and evaluating output than deal outcomes alone.
He cautions that Canva's announcement is a concrete case study, not proof that an archive of past work protects a software company from competition. Links to his own longer analysis (AI-assisted).
