DecompRL: Solving Harder Problems by Learning Modular Code Generation

Juliette Decugis, Fabian Gloeckle, Francis Bach +2

How can Large Language Models (LLMs) solve problems they currently cannot? Repeated sampling scales test-time compute but GPU cost grows linearly with attempts, while reinforcement…

LemmaBench: A Live, Research-Level Benchmark to Evaluate LLM Capabilities in Mathematics

Antoine Peyronnet, Fabian Gloeckle, Amaury Hayat

We present a new approach for benchmarking Large Language Model (LLM) capabilities on research-level mathematics. Existing benchmarks largely rely on static, hand-curated sets of c…

Formalizing Mathematics at Scale

Ahmad Rammal, Niket Patel, Fabian Gloeckle +5

We present AutoformBot, a multi-agent system for building an Autoformalized Textbook Library At Scale (Atlas) in Lean 4. AutoformBot orchestrates thousands of LLM agents, equipped…

WybeCoder: Verified Imperative Code Generation

Fabian Gloeckle, Mantas Baksys, Darius Feher +5

Recent progress in large language models (LLMs) has substantially advanced automatic code generation and formal theorem proving, yet software verification has not seen comparable g…

Automatic Textbook Formalization

Fabian Gloeckle, Ahmad Rammal, Charles Arnal +4

We present a case study where an automatic AI system formalizes a textbook with more than 500 pages of graduate-level algebraic combinatorics to Lean. The resulting formalization r…

ProofOptimizer: Training Language Models to Simplify Proofs without Human Demonstrations

Alex Gu, Bartosz Piotrowski, Fabian Gloeckle +2

Neural theorem proving has advanced rapidly in the past year, reaching IMO gold-medalist capabilities and producing formal proofs that span thousands of lines. Although such proofs…
