Nemotron-Cascade Paper Review: Cascade RL + RLHF/RLVR for Scalable General-Purpose Reasoning (14B)

📌 Nemotron-Cascade introduces Cascade RL: sequential, domain-wise reinforcement learning for reasoning LLMs 🧠 Supports both instruct mode and deep thinking mode in a unified general-purpose model 🧩 Tackles cross-domain heterogeneity in response length and verification latency that slows RL training 🧪 Uses RLHF as a powerful pre-step that boosts reasoning beyond preference alignment 📈 Subsequent domain-wise RLVR stages rarely degrade earlier domain performance and can even improve it 🏆 Reports strong results: 14B model surpassing its SFT teacher (DeepSeek-R1-0528) on LiveCodeBench and IOI-level performance 🛠️ Shares practical training recipes, reward modeling, and data curation insights for scalable RL training #AI #LLM #CascadeRL #RLHF #RLVR #Reasoning #NemotronCascade #DeepThinking #LiveCodeBench #arXiv
