arXiv:2607.02686v1 Announce Type: new Abstract: Reinforcement learning agents operating under partial observability must act on incomplete information, making them natural candidates for guidance from small language models (SLMs) that carry broad reasoning priors. Yet integrating SLM guidance into this setting has proven difficult: across all test environments, vanilla uncertainty-gated approaches achieve an overwrite rate at or near zero, meaning the SLM almost never contributes an independent action. We trace this failure to the bare egocentric prompt, which provides insufficient context for
The rapid development of smaller, more specialized language models (SLMs) and the increasing complexity of partially observable environments in AI are converging.
Improving the integration of language models into autonomous agents operating with incomplete information is crucial for advancing AI capabilities in real-world scenarios.
This research highlights a significant barrier to effective SLM integration, shifting focus from minor prompt adjustments to deeper contextual mechanisms for agent guidance.

Vanilla uncertainty-gated approaches for LLM assistance in partially observable environments are largely ineffective.
Future research will prioritize more sophisticated context integration methods for SLM guidance in autonomous agents.
This could accelerate the deployment of more robust and adaptable AI agents across various industries, from logistics to defense.
