Unified Training Algorithm Consolidates LLM Lifecycle Stages
October 28, 2026
A new framework unifies pretraining, SFT, and RL into a single maximum-likelihood training algorithm. By treating RL objectives as fitting to model-generated distributions, the lifecycle becomes a problem of data proportion and scheduling rather than algorithmic switching.
