Claude Opus 5.5 vs GPT-6 Astra: 3D mechanical centipede comparison
Given the same prompt for a desert mechanical centipede, Opus 5.5 shows more detailed armor panels and joints, while Astra's design is simpler and less consistent across angles.
Opus 5.5 keeps changing the game. It's getting ridiculous how much detail this model can handle. I put Claude Opus 5.5 and GPT-6 Astra side by side to see how they handle the same challenge: a giant mechanical centipede crawling through the desert. The difference gets interesting when you look closer. > Opus built a silver armored body with individual panels and gold joints. Astra went with a simpler, angular design. > Look at the legs. Opus has detailed mechanical hinges running along the entire body. Astra's are mostly thin black rods. > At 0:08, the camera moves above them. Opus keeps its segmented armor consistent from head to tail. Astra looks more like an exposed geometric frame. > Even the heads are different. Opus has layered mandibles and curved antennae, while Astra uses much simpler shapes. Both created a recognizable mechanical creature, but Opus looks far closer to something you'd actually see in a sci-fi game. The real difference isn't just detail. It's how well that detail holds together from every angle. The prompts and full setup are in the article below👇
