MassGen
MassGen is a terminal-based multi-agent system that runs several AI models on the same task in parallel, has them critique and build on each other's answers over repeated rounds, and lets the agents vote on the best result.
MassGen is a multi-agent framework that runs in the terminal. It coordinates several AI agents on the same task through redundancy and iterative refinement: each agent works the full problem, observes the others' progress, critiques it, and builds on it across repeated cycles.
When the agents judge that an answer is strong enough, they vote and the most broadly validated answer is returned. The project extends earlier ideas about iterative refinement and multi-agent conversation, and can also be installed as a skill inside Claude Code, Cursor, Copilot and other coding agents.
