Open-Source Model

A machine learning model whose source code, training data, and weights are publicly available for inspection, modification, and redistribution.

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).

The gary-explains channel reviewed the Nemotron-3 Nano in their video Nematron 3.

Example: Alibaba OvisOCR2

Alibaba has open-sourced OvisOCR2, a compact local document parsing model designed to surpass traditional pipeline-based methods.
