Comparing Similarity and Performance of AI Optimizers
eliebakouch · x · 2026-07-19
The author shared comparison charts of various AI optimizers (like Adam mini, SCION, SOAP, etc.).
- Similarity: Adam mini and SCION perform very similarly, whereas Cautious Adam differs significantly from SOAP.
- Scaling Law Validation: Experiments tested cross-parameter scale consistency for optimizers—meaning whether an optimizer performing best on a 1.2B model applies equally well to a smaller 520M model. Results show most optimizers follow this rule, except for SOAP.
