Made this 3D worm animation entirely out of code, one clip on Opus 5, one on Opus 5.5.

Without the captions, can you tell which is which?

This is the most insane thing i've seen an AI do all year

An early tester gave Opus 5.5 one job: migrate 680,000 lines of code. a team would burn weeks on it it finished in under a day another let it run overnight across six repos, unattended. it stayed on task for over 18

I gave Claude Opus 5.5 a single prompt: 5 agents, a "triple A quality" Mario Kart, and zero questions.

This came out. 8 characters, drifts, objects and more than 9,000 lines of code. I didn't write one. Opus 5.5 came out today and Anthropic says it costs 40% less than Opus 5.

Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family.

It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.
