## Summary

The authors introduce Software World, a simulation framework for multi‑agent collaboration in realistic software ecosystems. The framework creates environments of real, interdependent Python packages, allowing agents to maintain and improve software efficiency.

In simulations across three worlds, the authors ran more than 10,000 hours of agent work using eight different models. They measured speedup in hidden dependent packages and found that performance improvement scales with inference‑time compute. The best model achieved a downstream efficiency gain of up to 31%, while some frontier models stopped searching for improvements early.

The authors release the simulation framework and trace data at https://szj.io/sw, inviting further studies of agent collaboration and resource allocation in software development.

## Key points

- software world simulates multi‑agent collaboration using real python package ecosystems
- three worlds simulated, totaling >10,000 hours of agent work across eight models
- best model improves downstream efficiency by up to 31%

## Why it matters

The framework enables systematic study of agent collaboration, informing design of more efficient AI systems that can work together on complex software tasks, potentially accelerating software development and AI research.
