Multi-Agent Orchestration Beats Expanding Context Windows for Long Context

A developer argues that the industry is wrong about long context, suggesting we should forget 2M/5M context windows at the model level and solve it at the harness/infrastructure level.

Their team at INT21 shared their engineering practice: instead of waiting for larger context windows, they use multi-agent orchestration. When dealing with massive codebases that exceed context limits, they run multiple model instances in parallel, with each agent studying a different portion of the codebase and combining findings at the end. This approach of breaking a massive context problem into coordinated, smaller, evidence-seeking tasks is structurally better at filtering noise and preserving key evidence than simply expanding the context window.
