Nemotron-Cascade 2
Open-weight 30B Mixture-of-Experts (MoE) architecture: Features 30 billion total parameters with only 3 billion activated parameters per token, enabling efficient performance.
Advanced Reasoning Capabilities: Delivers best-in-class reasoning, especially in mathematical problems and coding tasks. It has achieved gold-medal level performance in the 2025 International Mathematical Olympiad (IMO) and the International Olympiad in Informatics (IOI).
Strong Agentic Capabilities: Equipped with robust abilities for agentic tasks.
Operating Modes: Supports both a "Thinking Mode" for deep reasoning in complex math and code tasks (activated by a `<think>` token) and a "Non-Thinking Mode" for more efficient, direct responses.
Structured Tool-Calling Protocol: Utilizes a defined protocol within the system prompt for effective tool use in agentic applications.
Post-training Pipeline: Built using the Nemotron-3-Nano-30B-A3B-Base model and refined through a post-training pipeline involving Cascade RL and Multi-domain On-Policy Distillation (MOPD).
