Training Reasoning Models on Saturated Problems via Failure-Prefix Conditioning

Minwu Kim, Safal Shrestha, Anubhav Shrestha +1

As Reinforcement Learning with Verifiable Rewards (RLVR) substantially improves the reasoning abilities of large language models (LLMs), a new bottleneck emerges: more training pro…

On the Limits of Layer Pruning for Generative Reasoning in Large Language Models

Safal Shrestha, Anubhav Shrestha, Aadim Nepal +2

Recent work has shown that layer pruning can effectively compress large language models (LLMs) while retaining strong performance on classification benchmarks, often with little or…

Warm Up Before You Train: Unlocking General Reasoning in Resource-Constrained Settings

Safal Shrestha, Minwu Kim, Aadim Nepal +2

Designing effective reasoning-capable LLMs typically requires training using Reinforcement Learning with Verifiable Rewards (RLVR) or distillation with carefully curated Long Chain…

Layer Importance for Mathematical Reasoning is Forged in Pre-Training and Invariant after Post-Training

Aadim Nepal, Safal Shrestha, Anubhav Shrestha +4

Large language models improve at math after instruction tuning, reinforcement learning, or knowledge distillation. We ask whether these gains come from major changes in the transfo…

Reinforcement Learning vs. Distillation: Understanding Accuracy and Capability in LLM Reasoning

Minwu Kim, Anubhav Shrestha, Safal Shrestha +2

Recent studies have shown that reinforcement learning with verifiable rewards (RLVR) enhances overall accuracy (pass@1) but often fails to improve capability (pass@k) of LLMs in re…
