arXiv:2605.29860v1 Announce Type: new Abstract: When a large language model under reinforcement learning commits a wrong reasoning step early in a trajectory, standard algorithms force it to keep generating until the maximum horizon, spending compute on tokens that never receive positive reward and polluting advantage estimates with post-failure noise. We propose ESPO (Early-Stopping Proximal Policy Optimization), which detects trajectory failure on-the-fly and terminates rollouts early. At each generation step, ESPO computes a surrogate regret using only the logits already computed during sam
The rapid scaling of large language models and the computational expense of reinforcement learning necessitate more efficient training methods to manage resource consumption and accelerate development cycles, especially as models are integrated into agentic systems.
Improving the efficiency of reinforcement learning for large language models directly impacts the cost and speed of AI development, enabling faster iteration and deployment of more capable AI agents.
This invention means LLMs can be trained more efficiently by avoiding wasted compute on failed reasoning paths, accelerating the development of more robust and intelligent AI systems.
