Example: NVIDIA Nemotron-3 Family
NVIDIA recently released the Nemotron-3 family of open-source models, featuring three sizes:
- Nano: 30-billion parameters (3-billion active via Mixture-of-Experts architecture).
- Super: 100-billion parameters (10-billion active).
- Ultra: 500-billion parameters (50-billion active).
