### Key Observations
- **Win Rates**: Kimi-K2-Instruct achieves the highest win rates across all comparisons, increasing from 59.6% (vs DeepSeek) to 65.4% (vs ChatGPT-4o-latest).
- **Tie Rates**: Decrease as opponent strength increases (23.5% → 17.6%), suggesting fewer inconclusive outcomes against stronger models.
- **Loss Rates**: Relatively stable (16.6–17.0%), indicating consistent performance even against advanced models.
### Interpretation
The data demonstrates that **Kimi-K2-Instruct** outperforms all three compared models in open-ended evaluations, with performance gains against stronger opponents (e.g., ChatGPT-4o-latest). The decline in tie rates suggests that Kimi’s interactions with advanced models result in more decisive outcomes (wins/losses) rather than ambiguous ties. The stable loss rates imply that when Kimi fails, it does so in closely contested scenarios, highlighting its robustness in competitive settings. This positions Kimi-K2-Instruct as a leading model in handling complex, open-ended tasks.
