By PulseAugur Editorial · [1 sources] ·

A user conducted a non-scientific comparison between Claude Opus 4.6 and 4.8, using Codex 5.5 as the judge. The results indicated that Claude 4.8 performed better overall in understanding the codebase and detecting risks, despite being slower and more verbose. Codex 5.5, acting as the judge, also reflected that while Claude 4.8 was a more thorough investigator, its own output would have been more concise and efficient. AI
