Multimodal Models

Image security has an awkward habit of sounding theoretical until the image is inside a business workflow. A product team adds an image-upload feature. A compliance team uses multimodal models to inspect screenshots. A support bot reads photos from customers. A research assistant summarizes figures from PDFs. Everyone understands that the model may occasionally misread an image. That is ordinary error. Annoying, but ordinary. ...

MemCtrl: Teaching Small Models What Not to Remember A robot assistant walks through a room. It sees a chair from the front. Then from the side. Then from a slightly worse angle. Then the same chair again, because the camera moved while the robot hesitated. In theory, all of this is “context.” In practice, it is mostly noise wearing a productivity badge. ...

A reaction scheme looks like a picture. To a chemist, it is closer to a compressed process model. A few arrows may encode the starting materials, catalysts, solvents, temperatures, intermediate states, selectivity, yield, and the structural change that makes the entire experiment worth publishing. Reading that scheme correctly is already difficult. Reading the paper around it is worse. ...

A chair is not a picture of a chair. That sounds obvious until a text-to-3D system forgets the backrest from one angle, gives the chair three legs from another, paints the seat correctly, and somehow convinces a weak evaluator that the job is mostly done. In 2D generation, a model can often survive by producing a plausible view. In 3D generation, every view is a witness. Geometry, texture, object parts, and spatial relationships all have to agree. Annoying, yes. Also the entire point. ...
