Do you choose a proprietary frontier model and get moving quickly? Build on an open model and gain greater control? Fine-tune your own version?
Change strategy six months from now when the economics and capabilities shift again? There may not be one right answer. But for founders, choosing badly can affect almost everything that follows — cost, infrastructure, margins, differentiation, speed, and control.
That decision is at the center of the session “The Open vs. Closed AI Debate Is Just Getting Started,” coming to the Builders Stage at TechCrunch Disrupt 2026, happening on October 13-15 in San Francisco. Led by Nvidia‘s Nader Khalil, Director of Developer Tech, and Sydney Sykes, Global Head of VC Partnerships, the session will discuss the trade-offs between open and proprietary AI and whether either approach can provide a lasting competitive advantage.
This isn’t a philosophical argument about open source. It’s a business decision being made right now inside startups of every size. Dive deep into this AI debate with 10,000+ tech leaders at Disrupt by getting your pass.

Nvidia said in July that 145 papers accepted at ICML 2026 cited its Nemotron open models and datasets, alongside research using other Nvidia open model families across robotics, autonomous vehicles, and biomedical research.
At the same time, proprietary frontier labs continue pushing model capabilities forward. The result is a market where the question is increasingly less about whether open models can be useful and more about where each approach makes commercial sense. Even Nvidia rejects a simple either-or framing.
