NVIDIA's AI Just Won a Gold Medal in Math — And I Tested It Locally!

NVIDIA just dropped one of the most capable open-source AI models of 2026 — and I tested it right on my own machine using Ollama and OpenWebUI. No cloud. No API bills. Just raw local AI power. Nemotron-Cascade-2-30B-A3B is a 30 billion parameter Mixture of Experts model that only activates 3B parameters at a time — meaning it's fast, efficient, and surprisingly easy to run locally. I put it through a range of questions — from tricky math problems and coding challenges to creative writing, science questions, and reasoning tasks. It handled almost everything impressively well. This model is a…
