Teaching AI to Read Crystals, Not Just Text
MIT News notes that the approach doesn’t work well yet, and the problem comes down to data: most materials are crystals — 3D periodic arrangements of atoms whose structures are stored in specialized formats, not the text streams that large language models are trained on. MIT researchers have now created a multimodal AI model that tackles the problem by combining 3D atomic structures with natural-language descriptions.

Take
MIT News notes the experimental literature is heavily biased toward a few popular classes of crystals, so any model trained on it risks skewing toward those materials.
Pushback
The model also draws on first-principles computational databases, not just the experimental literature, so that text bias may not be the whole story.
