Claim: CatBoost outperforms other GBM libraries on public benchmarks and ships with concrete implementations: symmetric trees for very fast prediction, permutation-based categorical statistics to avoid target leakage, and a relaxed order-boosting scheme that reduces overfitting on small datasets. Benchmarks show ~20× GPU training speedups versus XGBoost and 30–60× faster prediction in latency‑sensitive settings; code, reproducible plots and tuned comparisons are available on github.
