LongCat-Flash-Prover: Advancing Native Formal Reasoning via Agentic Tool-Integrated Reinforcement Learning

TL;DR: A 560B-parameter MoE model achieves new SOTA in Lean4 formal reasoning via tool-integrated reasoning and hierarchical policy optimization.

Formal verification is gaining traction for AI safety and software reliability, driving demand for stronger automated theorem provers.

  • 560B-parameter MoE model with tool-integrated reasoning (TIR)
  • Hybrid-Experts Iteration Framework expands
AI Geopolitics

How policy, chips, capital, and company power shape AI.

Policy, export controls, funding, compute supply, industrial strategy, and big-tech positioning are treated here as core AI inputs, not side topics.
