Architecting AI Agents: Chains, Graphs, and Collectives

TL;DR. A taxonomy outlines three core architectures for AI agent systems in production: sequential chains, dynamic graphs, and concurrent event-driven collectives. - Each architectural type offers distinct capabilities and presents specific scaling limitations. - Choosing the correct architecture is crucial for avoiding pitfalls and enabling complex AI applications. - Many development teams do not consciously select an architecture, leading to inefficient designs.

• AI agent systems primarily use three architectures: chains, graphs, and event-driven collectives.
• The chain architecture, simple but brittle, is common for sequential tasks.
• Graph architectures allow for dynamic routing and decision-making, increasing complexity and robustness.
• Event-driven collectives offer high concurrency and autonomy for agents within a system.
• Misaligned architectures can lead to system failures and development bottlenecks.
