A gummy octopus you can stretch: Opus 5.5 vs GPT-6 Astra

The same brief—a gummy octopus you can grab and stretch in the browser—given to Opus 5.5 and GPT-6 Astra. The creator prefers Opus’s squishier, brighter version and estimates its API cost at $14.01 versus $20.74.

Creator-reported playable siteWeb & UI

A jiggly, see-through “zero productivity” website made with Opus 5.5

A deliberately useless website of wobbling, translucent shapes you can poke. The creator says jiggle and transparency effects got much better with Opus 5.5, with fewer tokens.

A candy-colored 3D run, made in one early Sonnet 5.5 chat

A 30-second multi-camera animation: a small blob character wakes up in a grey world, the scene floods with color, and a countdown sends it racing. The creator says one Sonnet 5.5 chat session made it.
