One prompt, two models, a motion reel each
Kirill gave Claude Opus 5.5 and GPT-6 Astra the same brief: a 15-second motion-design showreel, go all out. He thinks looking at Astra hurts after Opus. The pair is the point.
The prompt is identical, which is the only way the comparison is fair. Kirill asked Claude Opus 5.5 and GPT-6 Astra each to make a 15-second motion-graphics reel "that shows what an incredible motion designer you are," and to go all out. His verdict is partisan: after Opus, Astra hurts to look at.
You do not have to share the verdict to see why the post belongs here. Motion design is taste under a stopwatch — type, timing, when to shut up. Two models, one sentence, code-rendered rather than filmed, so neither can hide behind stock footage.
A/B tests of writing are common. A/B tests of a showreel are not, because the failure is visible in a second and cannot be talked away.

after Opus 5.5 it actually hurts to look at anything GPT 6 Astra designs gave both models the exact same prompt: "make a dynamic 15-second motion graphics video that shows what an incredible motion designer you are, like it's your showreel for a résumé. go all out." not even https://t.co/ZO2nKrW13d
