Reasoning Core: Designing Broad Procedural Data for Completion-Supervised Reasoning Training

Damien Sileo, Valentin Lacombe, Dimitri Kachler

Procedural generators produce useful verifiable reasoning problems at scale, but have received less attention as data for completion-supervised fine-tuning. We introduce Reasoning…

Same Formulas, Different Semantics: Do Language Models Follow Modal Logic Specifications?

Réemi Andrieu, Damien Sileo

Reasoning about necessity and possibility depends on assumptions about accessibility between worlds and about which objects exist at each one. The same inference may therefore hold…

Reasoning Core: A Scalable Procedural Data Generation Suite for Symbolic Pre-training and Post-Training

Valentin Lacombe, Valentin Quesnel, Damien Sileo

Training on verifiable symbolic data is a promising way to expand the reasoning frontier of language models beyond what standard pre-training corpora provide. Yet existing procedur…

Saturation-Driven Dataset Generation for LLM Mathematical Reasoning in the TPTP Ecosystem

Valentin Quesnel, Damien Sileo

The scarcity of high-quality, logically sound data is a critical bottleneck for advancing the mathematical reasoning of Large Language Models (LLMs). Our work confronts this challe…
