Nvidia Nemotron-Cascade 2 Wins Math and Coding Benchmarks With 3B Active Parameters; Post-Training Open-Sourced

Nvidia's Nemotron-Cascade 2 achieves gold-medal performance on math and coding benchmarks using only 3B active parameters via a mixture-of-experts architecture, with the complete post-training recipe now open-sourced. Small, efficiently trained models can now compete with much larger systems on specialized tasks, enabling edge deployment and lower costs in production AI pipelines.
