Run thousands of Codex agents in parallel on 36- to 48-hour quant research sessions
The startup Third Moment Research runs up to 10,000 agents at once, each using the default Codex harness in a Docker environment with 1 TB of market data and a research repository, to improve a baseline trading system. An outer harness examines tasks left unfinished and decides whether to retry, terminate or escalate to human review. By analyzing thousands of agent trajectories, Codex found a backtest bottleneck and shipped the fix to production. We wrote the prompt below, since the source doesn't share the one used.
