Created by a team of researchers from Chinese and US universities, MetaGPT is a new LLM-based meta programming framework aiming to enable collaboration in multi-agent systems by leveraging human procedural knowledge to enhance robustness, reduce errors, and engineer software solutions for complex tasks.

MetaGPT takes a one line requirement and builds user stories, competitive analysis, requirements, data structures, APIs, and other documents. It achieves that by replicating the structure of a software company. The researchers showed a demo where they ask MetaGPT to create a CLI blackjack game and have it generate all required artifacts including requirements, tests, and a working Python implementation of the game.
