Hybrid agents switch between latent reasoning and text-based tool use

arxiv.org 3 min read Editor score 6/10

HybridAgents use a HybridLink to move between latent and text modes, with continuous working memory intended to preserve hybrid context across turns. The design targets a trade-off between efficient internal reasoning and inspectable, tool-integrated agent behavior.

What

Hybrid Reasoning Agents combine latent-space reasoning with text-based interaction for tool use.

Method

HybridLink enables transitions between modes, while continuous working memory preserves context; HybridSFT and HybridRL train the model to coordinate and switch modes.

Why it matters

The paper reports lower token use, faster inference and lower cost, offering engineers a way to trade internal reasoning efficiency against inspectable tool interaction.
