### Which model should command a Red Alert army?

Jev Router won the round robin 8–4, ahead of Claude Sonnet 5 (8–4), GPT-5.6 Terra (8–4) and GPT-5.6 Luna (0–12). With 4 games per pair the order at the top is a signal, not a verdict.](https://evaljetty.com/openra/investigations/which-model.html)[Is it worth the cost?

### Is the expensive model worth it?

Not in this field: Jev Router delivered the cheapest wins ($0.17 per win), and per-game cost ranged from $0.03 to $0.47.](https://evaljetty.com/openra/investigations/cost-vs-outcome.html)
