Nvidia Nemotron-Cascade 2: Post‑Training Playbook Upsets Size Orthodoxy

Nvidia’s Nemotron-Cascade 2 uses a sequential post-training recipe to deliver top-tier math and coding performance while activating only 3B parameters at inference. The Cascade RL pipeline plus MOPD token-level distillation signals a shift toward intelligence-density strategies that cut serving cost and raise the value of training orchestration. Public materials across the Nemotron family sometimes report divergent headline sizes, a difference that likely reflects measurement conventions rather than an architectural contradiction.
