Codex's Effort Mode is Too Manual

guy-you-know · reddit · 2026-07-16

A user discusses Codex's effort mode: low effort tends to cause silly mistakes on complex tasks, while high effort overcomplicates simple tasks, wasting time and credits.

They question the absence of a true "smart auto mode" that adapts to task complexity, suggesting that spending a few seconds to evaluate request difficulty before assigning an effort level would better suit most use cases. Ultimately, they acknowledge that Codex is already highly capable, but its current mode-switching and strategy design just aren't smooth enough.
