Codex / Opus 5.5 · A seaside pelican-cycling comparison

The author shares a mobile-and-desktop seaside pelican-cycling comparison, labelling the upper result Codex and the lower Opus 5.5. The underlying Codex model is undisclosed and is not inferred; the Opus label is also author-reported. The post includes a full prompt and an external playable link, but no code or explicit mirroring license was found. Only the original recording and source links are archived; the external app is not counted as an on-site playable demo.
