Model: Claude Opus 5.5, GPT-6 Astra · Series: Code-rendered film: the "15-second showreel" prompt

Evidence: X post (2026-09-24): '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 close, see for yourselves. GPT is honestly terrible here, openai just has awful taste'

Human role: Gave both models the identical showreel prompt and posted the two results side by side; no other direction stated.

Pipeline: Same one-line prompt → each model writes its own motion-graphics code → two renders cut side by side

Lore: one-prompt, code-not-generated, showreel-prompt

Summary
This video, shared by creator Kirill Sh (@shneural), presents a side-by-side comparison of motion design showreels generated by Anthropic’s Claude Opus 5.5 and OpenAI’s GPT-6 Astra from an identical prompt. Both models generate synchronized kinetic typography, 2D/3D geometric animations, and technical HUD elements formatted as a professional motion designer’s portfolio.

Assessment
A side-by-side comparative demo of autonomous code-rendered motion graphics. Both models successfully output synchronized WebGL/canvas-style code animations and kinetic typography tailored to the prompt, demonstrating differing aesthetic styles (Opus leans into technical HUD/minimalist code aesthetics, while Astra adopts a contemporary acid-lime/chrome branding agency aesthetic).

Lyrics & themes
The audio is entirely instrumental electronic music tailored to each reel. Opus 5.5 features a steady, sync-heavy 120 BPM beat with mechanical audio cues; GPT-6 Astra features an energetic 144 BPM beat with percussion and glitchy vocal chops. The on-screen text across both revolves around motion design mantras, kinetic typography, rhythmic synchronization, and portfolio showcases.
