Learning to Refer: Client-Resolved Generation for Privacy-Aware Language Models

Client-Resolved Generation (CRG), a genera- tion interface that separates server-side generation from the lexical realization of input-derived content, is introduced, which provides a practical interface for privacy-sensitive cloud LLMs by reducing plaintext exposure across both input and output pathways while preserv-...

Funnel of Thoughts: Efficient Test-Time Scaling via Early Voting and Rollout Pruning

Funnel of Thoughts (FoT) is introduced, an inference-time method that preserves the full 32-trajectory voted accuracy while halving its attention FLOPs, a 28.8% reduction in full-model inference cost.

Answer-Conditioned Chains of Thought Degrade Verifiable-Reasoning Distillation in Large Language Models

This work shows that training a strong instruction-tuned reasoning model on its own answer-conditioned chains sharply lowers its verifiable-reasoning accuracy, and generates answer-blind data, because no correctness filter can see this damage in the data.
