Overview

• Research examines overthinking in Large Reasoning Models (LRMs)
• Identifies three patterns: Analysis Paralysis, Rogue Actions, Premature Disengagement
• Studies 4,018 software engineering task trajectories
• Shows overthinking reduces performance by 30% and increases costs by 43%
• Proposes solutions through function-calling and reinforcement learning

Plain English Explanation

Think of an AI model like a student solving math problems. Sometimes that student gets stuck thinking too much about the problem instead of actually solving it. This is what happens with [Large Reasoning Models](https://aimodels.fyi/papers/arxiv/danger-overthinking-examining-re...
