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. 👉 links in the comments #AI4Math #FormalMath #LeanProver #AutomatedReasoning #TheoremProving #ProofAssistant #MachineLearning #AIResearch #OpenScience #Lean4 #LeanLang

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. #AI4Math #FormalMath #LeanProver #AutomatedReasoning #TheoremProving #ProofAssistant #MachineLearning #AIResearch #OpenScience #Lean4 #LeanLang

One year ago, our small but mighty model NuminaMath-7B-TIR won the first progress prize of the AI Math Olympiad 🥇 We have come a long way since and we're exited for what comes next 🙌 If you don't know us yet, check out the link in the comments for the full blog post about Team Numina and the technical details behind our winning solution #AI4Math #FormalMath #LeanProver #AutomatedReasoning #TheoremProving #ProofAssistant #MachineLearning #AIResearch #OpenScience #Lean4 #LeanLang

New milestone for Project Numina and Kimi Moonshot! 🚀 We are open sourcing our KiminaProver-72B. This SotA theorem-proving model comes with Test-Time Reinforcement Learning Search and Error-Fixing Capability. We’re putting it to the test soon, with the IMO just around the corner 👀 Check it out👉 huggingface.co/collections/A… Read the blog post huggingface.co/blog/AI-MO/ki… #AI4Math #FormalMath #LeanProver #AutomatedReasoning #TheoremProving #ProofAssistant #MachineLearning #AIResearch #OpenScience #Lean4 #LeanLang
