Existing diversity metrics miss the mark, failing to capture the true variety in problem-solving strategies that could enhance LLM reasoning capabilities.

LLMs' "Aha!" moments aren't about magic tokens, but about explicitly verbalizing and managing uncertainty during reasoning, which drives performance.

LLM agents can learn to explore novel states and generalize to new tasks with a hybrid on- and off-policy RL framework that leverages memory.
