You give d1 something to look at (a webcam frame, a sketch, a photo, a support ticket, or a mix of text and images) and a short list of questions with fixed answer shapes: yes or no, a pick from options you name, or a rating on a scale you describe. It answers all of them in one go and puts a probability on every option. It never writes a sentence, so there is nothing to parse and no invented detail to check.
What is new compared with Clef is the size and the speed. At 3 billion parameters it answers a single question in about 8 milliseconds on a gaming GPU and 30 on a recent Mac, quick enough to ask the same question of every frame coming off a camera. Liquid built ten small games around that: open your palm to make a bird fly, freeze when the screen says red light, count your squats, draw something and let it guess. Each game is just typed questions asked again and again as the frames come in.
