Princeton Test Shows Few AI Models Profit in 500-Day Startup Simulation
Researchers at Princeton University created CEO-Bench to assess AI agents managing a fictional software company across 500 simulated days. Only three models ended above their starting capital, while most went bankrupt during the test. A non-AI rule-based heuristic outperformed nearly all of the models evaluated.
Key points
- →Princeton researchers developed CEO-Bench for long-term AI business simulation
- →Most AI models lost starting capital over 500 simulated days
- →Simple rule-based system beat nearly all tested AI agents
