Opus 5.5 vs DeepSeek V4.1 on a LEGO underwater scene
Given the same prompt, Opus 5.5 built a full brick coral reef with caustics and god rays plus a LEGO turtle docking a sub, while DeepSeek V4.1 Flash returned a grey floor and a yellow capsule.
Same prompt: a LEGO turtle pilots a yellow mini-sub through a coral reef and docks at an underwater station. Claude Opus 5.5 built the whole reef out of bricks: staghorn coral, sea fans, kelp, clownfish in anemones, a clam with a glowing pearl. Caustics ripple across the floor and god rays fall from the surface. The turtle waves from the glass cockpit, fish part around the sub, and the airlock lights chase toward the hatch as it docks. DeepSeek V4.1 Flash needed a fix pass just to stop the frame from blowing out white. What came back is a grey floor, a scatter of shapes and a yellow capsule.
