Nemotron Cascade 2 30B A3B Introduction We're excited to introduce Nemotron Cascade 2 30B A3B, an open 30B MoE model with 3B activated parameters that delivers strong reasoning and agentic capabilities. It is post trained from the Nemotron 3 Nano 30B A3B Base. Nemotron Cascade 2 30B A3B achieves gold medal performance in both the 2025 International Mathematical Olympiad (IMO) and the International Olympiad in Informatics (IOI). It operates in both thinking and instruct (non thinking) modes.
