Paddo.dev: Opus 4.8 Is 4x Less Likely to Let Code Flaws Pass — But the Honesty Tax Means More Tokens

paddo.dev·medium signal

Paddo.dev published an analysis of Opus 4.8's self-correction behavior, reporting the model is 4x less likely to let a flaw in its own code pass unflagged compared to 4.7. The tradeoff: increased self-correction means higher token consumption per task as the model catches and rewrites its own output more frequently. For agentic loops where reliability matters more than cost, this is a net win; for high-volume batch processing, the token cost increase is material.
