Excited to share our #ICML2026 poster on Numina-Lean-Agent, an open and agentic reasoning system for formal mathematics. If you are at @icmlconf and interested in formal mathematics, theorem proving, agentic systems, or #AIforScience, come visit our poster presented by @ahhwuhu Thursday, July 9 2026 2:30 PM – 4:15 PM Hall A We’d love to chat! #OpenSourceAI #AIagents #Lean4

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

#IMO2025 has begun a few hours ago, wishing a great Olympiad to all the students! We're eager to see how the different AIs perform, including ours 💪🔥 #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

Hello World! 👋 We're thrilled to officially launch the X account for Numina, dedicated to advancing frontier AI in mathematics. Stay tuned for updates on our research, achievements, and the future of mathematical AI! #AI4Math #FormalMath #LeanProver #AutomatedReasoning #TheoremProving #ProofAssistant #MachineLearning #AIResearch #OpenScience
