Fast‑Thinking AI Paints Better Pictures Than Bigger Models

Ever wondered why some AI art apps feel sluggish while others snap pictures in a flash? Scientists discovered that a clever “step‑by‑step” AI, called a visual autoregressive model, can outpace the massive diffusion models that dominate the scene. Think of it like building a LEGO castle one brick at a time and being able to see if the shape looks right before adding the next piece, instead of dumping all the bricks at once and hoping it works. By using a technique similar to “beam search,” the AI quickly discards dead‑end ideas and reuses earlier work, making the whole process up to ten times faster. In tests, a 2‑billion‑parameter autoregressive system created sharper, more detailed images than a 12‑billion‑parameter di…
