OpenThoughts: Data Recipes for Reasoning Models

ICLR 2026oral

Reasoning models have made rapid progress on many benchmarks involving math, code, and science. Yet, there are still many open questions about the best train- ing recipes for reasoning since state-of-the-art models often rely on proprietary datasets with little to no public information available. To…

SkillFactory: Self-Distillation for Learning Cognitive Behaviors

ICLR 2026poster

Reasoning models leveraging long chains of thought employ various cognitive skills, such as verification of their answers, backtracking, retrying by an alternate method, and more. Previous work has shown that when a base language model exhibits these skills, training that model further with reinforc…

ChartMuseum: Testing Visual Reasoning Capabilities of Large Vision-Language Models

NeurIPS 2025poster

Chart understanding presents a unique challenge for large vision-language models (LVLMs), as it requires the integration of sophisticated textual and visual reasoning capabilities. However, current LVLMs exhibit a notable imbalance between these skills, falling short on visual reasoning that is diff…

To CoT or not to CoT? Chain-of-thought helps mainly on math and symbolic reasoning

ICLR 2025poster

Chain-of-thought (CoT) via prompting is the de facto method for eliciting reasoning capabilities from large language models (LLMs). But for what kinds of tasks is this extra "thinking" really helpful? To analyze this, we conducted a quantitative meta-analysis covering over 100 papers using CoT and r…

MuSR: Testing the Limits of Chain-of-thought with Multistep Soft Reasoning

ICLR 2024spotlight

While large language models (LLMs) equipped with techniques like chain-of-thought prompting have demonstrated impressive capabilities, they still fall short in their ability to reason robustly in complex settings. However, evaluating LLM reasoning is challenging because system capabilities continue…
