Summary
Researchers introduced VITAL, a hybrid reasoning framework that selectively verbalizes informative tokens as anchors while keeping most computation in latent hidden states. It outperformed fully latent methods, achieving relative average accuracy gains of 9.6% on GPT-2 and 5.1% on Llama-3.2-1B at comparable reasoning lengths, and surpassed hybrid baselines with shorter reasoning trajectories on Qwen3-1.7B.
