New RL textbook arrives; authors argue classic RL formulations remain untapped for LLM fine-tuning

Aviv Tamar announced physical copies of his new RL book have arrived. Idan Barnea recommends it for its mathematical foundations of reinforcement learning, noting that today's RL for LLM fine-tuning mostly assumes known transition dynamics, while the book covers alternative formulations — arguing the full power of RL has yet to be tapped.
