Claude Code effort levels fail to improve code quality despite higher costs

By PulseAugur Editorial · [1 sources] ·

An experiment revealed that Anthropic's Claude Code, specifically version Fable 5.1, did not improve code quality or correctness across its different effort levels. The user found that the 'max' effort setting, which was 8 times more expensive and took significantly longer than the 'low' setting, produced code that passed the same tests and met the same specifications. While higher effort levels did result in more factored and defensive code, these improvements were not reflected in the benchmark's pass/fail metrics. AI

IMPACT Highlights potential inefficiencies in AI coding assistants, suggesting users should be cautious about higher-cost settings if they don't yield measurable improvements.

    Claude Code's Max Effort Cost Me 8x More. It Wrote the Same Code.

    <p>Claude Code has an <code>/effort</code> command with five levels: low, medium, high, xhigh, max. The help text for low says "quick, straightforward implementation with minimal overhead." The natural assumption is that the higher levels buy you better code, and that the price i…
