When a single large model independently completes long-chain tasks requiring more than dozens of reasoning steps, errors accumulate exponentially with chain length, whereas decomposing the task among multiple specialized agents can significantly reduce the error rate.

VerifiedIn long tasks, small deviations at each step of the AI accumulate along the chain, leading to compounding errors.80% similarUnverifiedIn long-chain reasoning, small errors at each step are cumulatively amplified, a problem the academic community refers to as compounding errors.77% similarUnverifiedLong-sequence tasks tend to have larger variance because errors accumulate along the time axis, requiring a greater number of repeated experiments to reduce uncertainty.77% similarUnverifiedLong-horizon agent tasks rely on reasoning-action loops such as the ReAct framework, where errors cascade and amplify along the chain, causing completion rates to fall far below those of single-step question answering.76% similar
