Sutton, Barto RL book maps LLM path
A Reddit user asks whether selected Sutton and Barto chapters are the right way to build RL foundations before diving into RL-for-LLM work like PPO, GRPO, tool use, math reasoning, and agents. The thread frames RLHF and policy optimization as the main bridge between classic RL and modern LLM research.
The chapter shortlist is directionally right, but it mixes core foundations with exactly the parts that matter most for modern RLHF-style systems. For LLMs, the useful bridge is less about textbook control and more about approximate methods, policy gradients, and preference-driven optimization.
- –Chapters 1, 3, and 6 are the right base: they establish MDPs, bootstrapping, and temporal-difference learning.
- –Chapters 9-11 and 13 are more relevant to LLM work than planning-heavy material because modern RL for language models leans on function approximation and gradients.
- –The Alberta reinforcement learning courses are a stronger structured path than reading the book alone if the goal is to move from theory into practice.
- –For RL-for-LLMs specifically, add RLHF-focused material early; classic Sutton and Barto explains the vocabulary, but not the training stack most people use today.
- –Tool use, agents, and math reasoning only become "RL" in the useful sense when you care about interaction, credit assignment, or preference optimization.
