Same task test: Opus 5.5 vs Astra build a browser gummy octopus
The author had both models make a grabbable, stretchable browser gummy octopus, preferring Opus's feel and its roughly $6.7 lower API cost.
Opus made it squishier, brighter, and cheaper 🐙🤯 Claude Opus 5.5 vs ChatGPT-6 Astra. Same task - make a gummy octopus you can grab and stretch right in your browser I much prefer the jelly feel of Opus’s version: the body squashes, the tentacles stretch, and everything jiggles when you let go. Those bright colors and translucent edges - it genuinely looks like gummy candy lol Astra’s is cute, but Opus gets my vote here. Especially with that price difference Estimated API cost: Opus - $14.01 Astra - $20.74 $6.73 cheaper, and I like the result more. Which one would you pick? 👀
