Building AI Agents in Rust — part 5 | Towards AI

Multi-agent crews in Rust let specialized roles (researcher, skeptic, editor) handle complex tasks better than one generalist agent, but latency and cost rise. Understanding when to parallelize vs sequentialize agents and how to route queries is critical for production LLM cost-efficiency.
