A convergence of recent research reveals a critical limitation in current large language models: single-agent systems struggle with consistency and reliability in high-stakes domains. Studies show that LLMs exhibit erratic behavior when handling complex cases, producing divergent outputs under minor prompt variations in clinical settings. Similarly, AI-assisted programming tools deployed in educational contexts demonstrate 'objective drift,' where locally plausible outputs diverge from stated task specifications. These failures underscore a fundamental challenge: relying on a single AI entity creates bottlenecks that propagate errors through downstream applications, particularly in domains requiring safety and precision.
