When to Re-Plan: Subgoal Persistence in Hierarchical Latent Reasoning

arXiv:2606.03741v1 Announce Type: new Abstract: Long-horizon reasoning requires a system to commit to medium-horizon intent without becoming rigid: re-plan too often and computation never coheres into multi-step structure; commit too long and the plan goes stale. We study this stability-adaptivity tradeoff in the latent reasoning setting, where multi-step computation occurs inside hidden state rather than externalized token traces. We extend the Hierarchical Reasoning Model (HRM) with a feudal-style manager-worker interface: a slow high-level module periodically emits a normalized directional

Why this matters
Why now

This research addresses a fundamental challenge in long-horizon AI reasoning, a critical bottleneck for advanced AI systems as their complexity and application scope increase.

Why it’s important

Improving AI's ability to balance commitment to long-term goals with adaptability to new information is crucial for developing more robust, autonomous, and intelligent agents.

What changes

The proposed 'feudal-style manager-worker interface' offers a concrete architectural improvement for hierarchical latent reasoning models, potentially leading to more efficient and capable AI systems in complex environments.
