New paper traces LLM reasoning from pretraining to post-training
gerardsans · x · 2026-07-21
- The paper studies the full LLM training pipeline, from pretraining to post-training.
- It reports a joint scaling law and uses it to reason about how compute should be allocated across stages.
- The authors also analyze what RL is doing to the policy, aiming to connect training choices with final model behavior.
