steve hsu(@hsu_steve):This is kind of amazing. 1. It's Xiaomi doing this, not a traditional AI power even among PRC companies. 2. Xiaomi seems very advanced in cost-effective RL. If they get serious about math capability, perhaps using Lean verification, they might catch up to OAI/ANT - their models are currently much better at math-phys than any OS model I have tested. Chinese AI companies have focused primarily on coding and agentic behavior.

A classic mathematical theorem. 6,000+ lines of Lean code. Verified by the kernel. Xiaomi MiMo 2.6 Pro assisted researchers in fully formalizing the original main theorem of Li–Yorke’s classic paper Period Three Implies Chaos in Lean 4. Guided by a research-designed exploration strategy, multiple Subagents collaborated on theorem formulation and proof formalization. After revision and integration, the project spans 6,000+ lines of Lean code, verified by Lean’s kernel with no unfinished proof placeholders. Notably, Xiaomi MiMo 2.6 Pro was not specifically post-trained for Lean. #XiaomiMiMo# #XiaomiMiMoV26# #AIforScience# #XiaomiAI#
