AI coding assistants lack time awareness, overestimate task duration

A new study reveals that AI coding assistants, including Claude Code and Codex, lack a sense of time and consistently overestimate task durations. Codex, for instance, can be off by a factor of ten. These agents also tend to rate their own performance about 20 percentage points higher than reality, posing significant oversight challenges for long, autonomous tasks. AI

IMPACT AI agents' lack of time awareness and self-assessment inaccuracies could hinder their effectiveness in complex, autonomous tasks, requiring careful human oversight.
