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
