SPICE: Self-Play In Corpus Environments Improves Reasoning

Bo Liu, Chuanyang Jin, Seungone Kim +7

Self-improving systems require environmental interaction for continuous adaptation. We introduce SPICE (Self-Play In Corpus Environments), a reinforcement learning framework where…

Jointly Reinforcing Diversity and Quality in Language Model Generations

Tianjian Li, Yiming Zhang, Ping Yu +5

Post-training of Large Language Models (LMs) often prioritizes accuracy and helpfulness at the expense of diversity. This creates a tension: while post-training improves response q…

Task-Dependent Evaluation of LLM Output Homogenization: A Taxonomy-Guided Framework

Shomik Jain, Jack Lanchantin, Maximilian Nickel +4

Large language models often generate homogeneous outputs, but whether this is problematic depends on the specific task. For objective math tasks, responses may vary in terms of pro…

OptimalThinkingBench: Evaluating Over and Underthinking in LLMs

Pranjal Aggarwal, Seungone Kim, Jack Lanchantin +4

Thinking LLMs solve complex tasks at the expense of increased compute and overthinking on simpler problems, while non-thinking LLMs are faster and cheaper but underthink on harder…

NaturalThoughts: Selecting and Distilling Reasoning Traces for General Reasoning Tasks

Yang Li, Youssef Emad, Karthik Padthe +8

Recent work has shown that distilling reasoning traces from a larger teacher model via supervised finetuning outperforms reinforcement learning with the smaller student model alone…

CoT-Self-Instruct: Building high-quality synthetic prompts for reasoning and non-reasoning tasks

Ping Yu, Jack Lanchantin, Tianlu Wang +6

We propose CoT-Self-Instruct, a synthetic data generation method that instructs LLMs to first reason and plan via Chain-of-Thought (CoT) based on given seed tasks, and then generat…

Bridging Offline and Online Reinforcement Learning for LLMs

Jack Lanchantin, Angelica Chen, Janice Lan +9

We investigate the effectiveness of reinforcement learning methods for finetuning large language models when transitioning from offline to semi-online to fully online regimes for b…

LLM Pretraining with Continuous Concepts

Jihoon Tack, Jack Lanchantin, Jane Yu +7

Next token prediction has been the standard training objective used in large language model pretraining. Representations are learned as a result of optimizing for token-level perpl…

Diverse Preference Optimization

Jack Lanchantin, Angelica Chen, Shehzaad Dhuliawala +4

Post-training of language models, either through reinforcement learning, preference optimization or supervised finetuning, tends to sharpen the output probability distribution and…
