as teams explore flavors of fine-tuning like SFT & RL, i think it’s helpful for someone on the team to internalize what behaviors each method “encourages” + how this happens + what type of model it produces
behaviors
- SFT=mode covering & RL=mode seeking
- how that relates to the loss
- the source of data (offline dataset vs model producing tokens and getting scored)
choose how deep you want to dive into the math but LLMs are great at drawing and redrawing the concepts until it makes sense
i’ve always found it helpful to plug numbers into the loss functions and see what number comes out and see what that means by what cases get rewarded vs penalized
a lot of observed behavior like catastrophic forgetting falls out of analyzing where the math is forcing the learning process
claude and chatgpt are fantastic ascii art and html drawers, have hundreds of these little diagrams trying to understand concepts in papers

Probing the Origins of Reasoning Performance: Representational Quality for Mathematical Problem-Solving in RL vs. SFT Fine-Tuned Models
This paper investigates internal representational differences between RL and SFT fine-tuned models on mathematical reasoning, finding that RL models exhibit more linearly separable hidden states and hierarchical layer importance. Token allocation variability under repeated sampling suggests training pipeline dependence rather than RL vs SFT alone.
