WANG Jianing (王嘉宁) is a Meituan LongCat researcher and first author of LongCat-Flash-Prover, a 560B open-source MoE model for native formal reasoning in Lean4. The Prover report introduces agentic tool-integrated reinforcement learning and reports strong open-weights performance on auto-formalization and theorem-proving benchmarks.

WANG Jianing is also listed on R-HORIZON, a benchmark and training-data method for long-horizon reasoning.
