Opus 5.5 vs GPT-6 Astra: same prompt, two jelly seaside worlds
Given the same prompt, Opus 5.5 and GPT-6 Astra each generated a tiny seaside world video; the author found Opus's water physics and animal movement more lifelike, though its API cost of $29 was higher.
The jelly world just got its own tiny ocean 🌊🍮 Claude Opus 5.5 vs GPT-6 Astra - same prompt, two tiny seaside worlds Opus wins this one for me. I really liked its water physics and animal movement - the shimmering reflections and spreading ripples make the whole scene feel alive. A little coastal escape you could watch for way too long. Though $29.08 is a little pricey for a ticket to the jelly beach Astra came in cheaper, but I wasn’t a fan of its water physics or overall visual quality. More “aquarium decoration” than “living underwater world.” Cute enough to put on a shelf, but Opus makes you want to touch the water Estimated API cost: Opus - $29.08 Astra - $17.86 Which jelly ocean would you dive into? 🪼
