Study reveals when multi-turn RL actually helps LLM agents
What is What Does Multi-Turn Reinforcement Learning Really Improve in LLM Agents??
The paper measures the benefit of reinforcement learning across multiple conversation turns for large language model agents. It shows the gains only appear when the model can explore many possible responses (breadth) and engage in deep interactions (depth).
Who it is for
Researchers and product teams building LLM assistants should read it to gauge whether multi-turn RL is worth the extra training cost.
