1 · Think first

The secret to AI seeing photos and hearing sounds wasn't giving it eyes and ears. Photos and sounds got cut into small pieces too, and lined up in the same row as word pieces.

Text gets cut into word pieces, photos into square tiles on a grid, and sound into very short slices of time. Once they're cut, all three are just 'pieces in a row.'

That means there's no need to build a new design. You can feed them straight into the Transformer, which lets pieces look at each other. Because it handles several senses at once, it's called multimodal.

2 · Experiment · Split it up

Try it — Split text, photos and sound into pieces

Tap the buttons to switch what goes in. If you can see that whatever you put in ends up as pieces standing in a row, you've got it. Orange marks the pieces to watch right now.

In 2023, the ability to read photos opened up widely; in 2024 came a model that learned text, photos and sound in one design, and its spoken replies got as fast as 0.32 seconds on average.
