The Importance of Rigorous Hyperparameter Tuning
Our study underscores that accurate hyperparameter tuning is foundational for fair optimizer comparisons and unlocking true performance. Many previous claims of significant speedup were found to stem from insufficiently optimized baselines.

Critical
Hyperparameter tuning is paramount; suboptimal settings can make a superior optimizer underperform, revealing that blind hyperparameter transfer is unfair.
Understanding Real-World Optimizer Performance Across Scales
While many novel optimizers claim substantial speedups, our rigorous testing reveals a more nuanced reality, especially as model scales increase. Understanding these dynamics is crucial for large-scale enterprise deployments.
1.1x
Realistic speedup over AdamW for 1.2B parameter models, significantly less than the claimed 1.4-2x.
| Feature | Scalar-Based Optimizers (e.g., AdamW, Lion) | Matrix-Based Optimizers (e.g., Muon, Soap, Kron) |
|---|---|---|
| Update Mechanism | Individual parameter updates using entry-wise scalar operations. | Leverage inherent matrix structure; precondition gradients via matrix multiplication. |
| Performance on Small Models (0.1B-0.5B) | Achieve similar speeds to AdamW, with <1.2x average speedup. | Deliver ~1.3x speedup over AdamW. |
| Performance on Large Models (1.2B) | Speedup diminishes to ~1.1x. | Speedup diminishes to ~1.1x. |
| Data-to-Model Ratio Sensitivity | Less sensitive to shifts in optimal performance across different data regimes. | Optimal choice shifts; Muon outperforms at lower ratios, Kron/Soap gain advantage at higher ratios (8x+ Chinchilla). |
Dynamic Optimizer Selection: Data-to-Model Ratio Matters
Our findings highlight that the optimal choice of optimizer is not static; it critically depends on the data-to-model ratio. For example, while Muon consistently leads at smaller Chinchilla ratios (e.g., 1-4x), its performance is outperformed by Kron and Soap when the data-to-model ratio increases to 8x or larger. This suggests that enterprise AI strategies must account for training data density when selecting optimizers.
Avoiding Misleading Early-Stage Evaluations
Evaluating optimizers prematurely can lead to flawed conclusions. Our research demonstrates that intermediate checkpoints and inconsistent learning rate decays often present an inaccurate picture of long-term performance.
Misleading
Early-stage loss curves can be highly misleading; rankings often flip due to learning rate decay, emphasizing end-of-training evaluation.
Unfair
Blind hyperparameter transfer across optimizers is unfair, as optimal settings for one may be suboptimal for another.
