What is L2MAC?

L2MAC is a framework for a general-purpose stored-program "automatic computer" implemented as an LLM-based multi-agent system. From a one-line input prompt, it generates large outputs such as an entire complex codebase. Internally, it creates and executes a prompt program made of a series of instruction steps on its own; each step is handled by a new LLM agent, and a control unit manages the context. Agents read and write persistent memory in the form of a file store, and can use tools that run syntax checks and unit tests. The related paper was accepted at ICLR 2024.

  • Work around context limits through collaboration of multiple LLM agents
  • Generate large outputs such as codebases and books from a single prompt
  • Memory that stores and uses past interactions and outputs
  • Automatic generation and execution of sequential prompt programs
  • Integration with syntax-check and test-execution tools
  • Customize task execution steps

Who uses L2MAC and for what

  • Generate an entire app codebase from a one-line prompt
  • Write book-length text
