View on XWe put Claude Opus 5.5 and ChatGPT Astra head-to-head for JavaScript animation. Observed something crazy!!!! Opus 5.5 didn't write a single line of code for the starting 30 minutes! Both took around 50 minutes to finish. But look at how they spent that time: - Opus 5.5: ~30 minutes thinking, ~20 minutes building. - ChatGPT Astra: ~10 minutes thinking, ~40 minutes building. Opus spent more than half the run thinking before getting into the build. which is kinda interesting! I prefer Opus’s glass, lighting and denser city. Astra makes the planet and galaxy easier to follow. but it lacks at the details. Side by side Comparison. Opus on the left, Astra on the right. Which side are you?
