# HALO Adds Adaptive Latent Reasoning on Top of Frozen Language Models

The method spends a small, input-dependent amount of extra compute refining a backbone's hidden states rather than fixing the number of refinement steps.

A new preprint, HALO: Hybrid Adaptive Latent Reasoning, studies how to improve a frozen pretrained language model with a small amount of extra computation applied at inference. The straightforward approach adds a fixed number of refinement…
