What people think

One user fed both models a script meant to print the max of two numbers; Opus 5 deduced it correctly, while Opus 5.5 wrongly concluded it prints 1/0. One user reported that Claude Opus 5 broke ten things every turn while producing incomprehensible babble during coding, prompting them to switch from Claude Code to Codex.

“any gap in specificity in my statement of a task would lead Opus 5 to invent an interpretation to fill the gap, frequently creating lots of extra work for itself in the process, and often deviating from my intent”

From the same comment ↗

I feed it a script which takes two numbers and prints the max of the two numbers. Opus 5.5 thinks it prints 1/0 instead of the max numbers.
