MoE is Fragile During SFT; Coding Scaling Laws Vary Drastically Across Languages
mdancho84 · x · 2026-08-12
The author discusses model fine-tuning and coding task characteristics:
- MoE vs Dense: While MoE models have higher capacity, they are more fragile during SFT, with hyperparameter sensitivity and routing stability issues.
- Coding scaling laws aren't uniform: Different programming languages require vastly different amounts of data to specialize. Some "enterprise-y" languages look easier to learn, whereas heavily used ones like Python and JS can be trickier.
