MetaGPT is an open-source Python framework that structures LLM agents into a simulated software company, assigning roles such as product manager, architect, project manager, engineer, and QA engineer. Agents communicate via a shared message pool using Standardized Operating Procedures (SOPs) encoded as prompt sequences. A single natural language requirement can produce user stories, competitive analysis, system design, data structures, API specs, and working code. Version 1.0 introduced Foundation Agent technology, and MGX (MetaGPT X) launched in February 2025 as a hosted AI agent development team. Key features: - Role-based multi-agent system: PM, architect, engineer, QA, and more - Shared message pool architecture for clean agent-to-agent communication - SOPs (Standardized Operating Procedures) encoded as structured prompt sequences - Produces full software artifacts: requirements, design docs, code, and tests from one prompt - MGX hosted platform for no-infrastructure multi-agent development teams - Extensible: supports OpenAI, Anthropic, and other LLM backends
