The Codex Loop
Built at OpenAI Codex Hackathon · Feb 5, 2026

Codex should allow engineers to focus on developing their most important and newest ideas without being bogged down with easier new improvements or fixes. Introducing the self improving Codex. A multi-agent system which finds new ideas and writes the code for it. All in a closed loop. Multi-Agent Agents: - Looks through Twitter and Github to find things to improve - Comments/Messages/DMs people for more information - Clusters and ranks using embedding scores from rerank models - Creates PRs and writes the code with parallel agents
