Nemotron-Cascade 2
Nemotron-Cascade 2 is a sparse reasoning model post-trained through cascade reinforcement learning and multi-domain on-policy distillation. The training recipe transfers specialist strengths across mathematical reasoning, coding, science, and instruction following into a compact active-parameter model. It supports thinking and non-thinking modes and very long context. NVIDIA releases weights, training datasets, and reproducibility materials, making the checkpoint useful for reasoning research as well as self-hosted assistants. Competition-level results may rely on extended inference or tool setups.
