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

Chanhee Park, Sungbin Han, Jeongho Yoon +2

Large Reasoning Models produce diverse, sometimes inconsistent answers across repeated queries on the same problem, so multi-sample inference is a prerequisite for reliable deploym…

Flat Score, Amplified Failures: How the Error Budget Masks Damage in Quantized LLM Agents

Jiwon Jang, Kisu Yang, Heuiseok Lim +1

The paper evaluates 4-bit post‑training quantization of multi‑turn, tool‑calling LLM agents and finds that while standard scores remain unchanged, quantization substantially increa…

LAMAR: An Open Language-Aware Multilingual Alignment Reranker

Seongtae Hong, Youngjoon Jang, Jungseob Lee +2

In multilingual retrieval augmented generation pipelines, an embedding model can retrieve relevant documents written in multiple languages, which are subsequently reranked before a…

To Isolate or to Score? Model-Adaptive Assessment for Cost-Efficient Multi-Agent RAG

Jungseob Lee, Chanjun Park, Heuiseok Lim

Multi-agent document assessment for retrieval-augmented generation is computationally expensive, driving practitioners toward smaller, deployable models whose assessment mechanisms…

DART: Draft-Agreement Routing for Training-Free Adaptive Thinking Budgets in Hybrid Reasoning Models

Jungseob Lee, Seongtae Hong, Seungjun Lee +7

Hybrid reasoning models can answer directly or spend extra tokens on extended thinking. A practical router should choose between these modes for each query, so easy problems avoid…

Beyond Penalizing Mistakes: Stabilizing Efficiency Training in Large Reasoning Models via Adaptive Correct-Only Rewards

Jungseob Lee, Seungyoon Lee, Seongtae Hong +3

Training large language models to reason efficiently is a critical challenge. While integrating length-penalizing rewards into Group Relative Policy Optimization (GRPO) aims to red…
