Hierarchical Prompt-Domain Control and Learning for Resource-Constrained Agentic Language Models

arXiv:2605.27703v1 Announce Type: new Abstract: Large Language Models are increasingly deployed inside agentic systems, where they must follow structured protocols, adapt to evolving states, and operate under memory, latency, and cost constraints. In such regimes, prompt extension is unreliable: growing contexts can push compact models outside their effective prompt domain, while deployment-time fine-tuning remains limited by scarce data and compute. We propose a hierarchical control-and-learning framework in which a compact model is first distilled to learn the required output schema, then su

Why this matters
Why now

The proliferation of agentic systems built on Large Language Models necessitates methods for efficient operation under real-world constraints like memory, latency, and cost, pushing research towards optimized control and learning frameworks.

Why it’s important

This research addresses fundamental resource limitations in deploying autonomous AI agents, enabling wider adoption and more sophisticated applications across industries by making powerful models more practical and cost-effective.

What changes

Current reliance on prompt extension is yielding to more sophisticated hierarchical control-and-learning architectures, allowing compact models to maintain performance and adapt in dynamic, constrained environments.
