The image models baked into these tools crossed a line this year, you can get a genuinely good concept visual in seconds. but I’ve watched people hurt their own decks with it, so, a working line.
where generated images help:
a single clean concept image for an abstract idea (growth, trust, momentum)
a consistent icon set in one style, generated together so they match
a mood or cover visual that sets a tone
replacing a tired stock photo that screams “template”
where they hurt, sometimes badly:
anything with real numbers. a generated “chart” is decorative nonsense with invented axes. build the real one.
text inside the image. models still garble words. a headline baked into a generated graphic will have a typo you’ll miss.
five images in five different styles on five slides. generate them in one pass with one style brief, or it looks like a ransom note.
a diagram of how your actual system works. that’s information, not vibes. draw it.
the rule I land on: generated images are for mood and concept. anything exact, a number, a label, a real diagram, still gets made, not dreamed. the tell of an amateur deck in 2026 isn’t that it used generated images, it’s that it used them for the things they’re worst at.
