Announcing Numina’s first Fellowship: Congratulations to Prof. Tamás Hausel & Project Sandbox (@ISTAustria ) 🎉
We're proud to support their vision of a verifiable research environment where AI agents and mathematicians collaborate to push the frontiers of mathematics.
Excited to see what they discover!

We formalized the proof of the 3D Kakeya conjecture in Lean from the Sticky Kakeya theorem.
Together with the unconditional Sticky Kakeya formalization by Nankai University × ByteDance Seed AI4Math, this gives a complete formal proof with no sorry and no project-specific mathematical axiom.
A great example of how AI can help turn frontier mathematics into machine-verified proofs.

The core idea is simple: instead of training a theorem-proving-specific pipeline from scratch, we explore whether a general coding agent can be turned into a strong formal mathematics reasoner by giving it the right tools through MCP.
Numina-Lean-Agent integrates Lean interaction, semantic theorem retrieval, informal proving, and multi-model discussion. In our experiments, it solves 12/12 Putnam 2025 problems, matching or surpassing several closed-source systems, while remaining #opensource.
Huge Milestone for AI & Math! 🚀Check out this thread by @Amaury_Hayat on the reasoning engine behind Numina xitter.cf/Amaury_Hayat/status/20…
📣 Calling Global Researchers
We are excited to announce the launch of the Numina Fellowship!
Designed for research groups looking to accelerate their work with AI specialized in mathematical reasoning, this fellowship aims to co-develop solutions to ambitious problems at the forefront of science and mathematics.
⏳ Deadline: March 30, 2026
💰 Numina will commit $50k-$200k

Standing on the shoulders of giant AI models, we utilize accessible models (Claude/Gemini/GPT-5.2) with a novel agentic reasoning loop.
The Brascamp-Lieb formalization (arXiv:2511.11091) took just 2 weeks. This demonstrates concurrent autoformalization: providing machine-checked guarantees while a paper is still under peer review.

This progress is built on the foundational work of the @Mathlib community. The future of math research lies in transparent tools that amplify human insight.
We are hiring Mathlib experts to join this effort.

Announcing Numina-Lean-Agent: an open-source framework achieving SOTA in formal theorem proving using generic models.
Two major breakthroughs: 🏆 12/12 on Putnam 2025 📜 Formalized the "Effective Brascamp-Lieb inequalities" research paper (>90% AI-generated)
Code: github.com/project-numina/nu…
Demo: demo.projectnumina.ai/
Paper: github.com/project-numina/nu…
We are hiring Mathlib experts to build a research-level autoformalization system. 🚀
With Numina-Lean-Agent, we achieved SOTA (12/12 Putnam 2025) and >90% autonomous formalization of the "Effective Brascamp-Lieb inequalities" paper.
Join us to build the transformation engine for formal mathematics.
Congratulations to our contributors @BaksysMantas and Jonas Bayer for their participation in the AITP 2025 conference! 💪🚀
During their talk they deep dived into the capabilities of our Kimina prover, which uses a Chain of (Formal) Thought reasoning pattern, allowing it to generate complex, human-like proofs and achieve an 92.2% pass rate on the miniF2F benchmark. 👀
We believe in open scientific collaboration. By open-sourcing our models and datasets, we aim to accelerate progress and build tools that bridge the gap between human intuition and formal verification.

We are proud to be Releasing NuminaMath-LEAN, a large-scale dataset of 100K mathematical competition problems formalized in Lean 4, with more than 20K human annotations.
Paired with Kimina-Prover, Kimina-autoformalizer, CombiBench, we hope these data and models will advance open-source AI for formal mathematics !
This year's IMO was bittersweet for Numina as our theorem prover did not solve any problem, we believed we were very close.
Numina is starting a new chapter after IMO 2025. While we will still continue to build SOTA open source theorem prover for high school problems, we would also like to branch out and explore undergraduate level math or even research level, open mathematical problems.
