Summary

MetaGPT is a multi-agent framework that encodes Standardized Operating Procedures (SOPs) into prompt sequences and assigns roles along an assembly-line workflow. The paper says solutions to more complex tasks are complicated through logic inconsistencies due to cascading hallucinations caused by naively chaining LLMs, and that SOP sequences allow agents to verify intermediate results and reduce errors. On collaborative software-engineering benchmarks, they report more coherent solutions than previous chat-based multi-agent systems. [S1]

When to apply

Use when looking at structured multi-agent software teams that encode human working procedures, rather than free-form chat between agents.
