Lean

Big day for Lean! Alex Gerko of XTX Markets is donating $10M to the Lean FRO and the new Mathlib Initiative to support the future of formal mathematics and machine-checked proofs. Thank you, Alex Gerko and Convergent Research, for believing in the mission. Read the full…

Check out the new use cases on lean-lang.org showing real-world #LeanLang applications! 📚 Mathlib: Nearly 2M lines of formalized math spanning algebra, analysis, topology & more 🦀 Aeneas: Rust → Lean verification toolchain for functional correctness in #Rust…

LeanTool is a utility that uses tool calls to link big language models (LLM's) to the Lean 4 theorem prover. It allows for interactive refinement, proof validation, and real-time syntax checking. The intended use is incorporating it both in automated workflows and…

CAV is officially underway 🚀 ⭐ #cav2025 #ceremony #verification

🚀 Excited to share that the Workshop on Mathematical Reasoning and AI (MATH‑AI) will be at NeurIPS 2025! 📅 Dec 6 or 7 (TBD), 2025 🌴 San Diego, California

While IMO is trending, our model leads on college-level math (Putnam Benchmark)—nearly doubling the problems solved by prior SOTA, with formal, verifiable proofs! Moreover, it’s not just an announcement—you can actually download and use our model. 🙂

An under appreciated fact about using formal methods like Lean is that it enables large-scale *collaboration* among mathematicians & potentially future AI agents. Why? Well, you can decompose a large proof into separate components that can be proven independently with robust…

This past week, Harmonic had the opportunity to represent our advanced mathematical reasoning model, Aristotle, at the International Mathematics Olympiad - the most prestigious mathematics competition in the world. To uphold the sanctity of the student competition, the IMO Board…

Start a thread on Terence Tao's fascinating #IMO2025 closing speech. He painted a vivid picture of a new era in mathematics, driven by tools like AI & formal proof languages (especially Lean), transforming math from a solitary art into a large-scale, collaborative science. 1/

It's happening today! 📍Location: West Ballroom C, Vancouver Convention Center ⌚️Time: 8:30 am - 6:00 pm 🎥 Livestream: icml.cc/virtual/2025/w… #ICML2025 #icml25 #icml #aiformath #ai4math #workshop

Goedel Prover V2 (blog.goedel-prover.com) will be featured at @ai4mathworkshop today. Come and discuss with us!

(1/4)🚨 Introducing Goedel-Prover V2 🚨 🔥🔥🔥 The strongest open-source theorem prover to date. 🥇 #1 on PutnamBench: Solves 64 problems—with far less compute. 🧠 New SOTA on MiniF2F: * 32B model hits 90.4% at Pass@32, beating DeepSeek-Prover-V2-671B’s 82.4%. * 8B > 671B: Our 8B…

The first volume of the new Open Access journal "Annals of Formalized Mathematics" was released today! ➡️afm.episciences.org/volume/view/id… #FormalMath #Mathematics #OpenAccess

This April, we released Kimina-Prover Preview. Stay tuned! Full release is coming soon 🚀 #AI4Math #FormalMath #LeanProver #AutomatedReasoning #TheoremProving #ProofAssistant #MachineLearning #AIResearch #OpenScience

Sharing this really interesting post about a custom-built #LeanLang environment to replace a Jupyter Notebooks workflow, over on LinkedIn: linkedin.com/posts/philip-z…

📣 We're excited to share the new lean-lang.org! Relaunching our website was a key deliverable in our Year 2 roadmap to provide "improved navigation and access to valuable content, resources, and tools." We hope you like it! #LeanLang #LeanProver

Computers can check whether mathematical proofs are correct, but only if they have been translated into a machine-readable form first. Now, AI has got surprisingly good at this translation - which could transform the way maths is done. newscientist.com/article/248719…
