Agentic Monte Carlo: Reinforcement Learning for Black-Box LLM Agents
ICML 2026poster
LLM agents operate in two distinct regimes: open-weight agents amenable to reinforcement learning (RL) and black-box agents whose behaviour must be controlled purely at test time. Although black-box agents are often backed by state-of-the-art proprietary LLMs, API-only access precludes parameter-lev…
