OpenAI puts o1 in Los Alamos supercomputer for 15,000 scientists

OpenAI is bringing its most advanced reasoning models to the U.S. National Laboratories, a move that embeds the company’s technology directly into the country’s most sensitive scientific and nuclear security work. The deal, announced Thursday, will see an o-series model deployed on Venado — an NVIDIA-powered supercomputer at Los Alamos National Laboratory — where it becomes a shared resource for researchers across Los Alamos, Lawrence Livermore, and Sandia National Labs.

That’s roughly 15,000 scientists suddenly getting access to frontier AI. The labs plan to use the models for everything from disease treatment and materials science to protecting the electrical grid and deepening our understanding of high-energy physics. OpenAI is framing this as mission-aligned: putting AGI in the hands of people who can use it for breakthroughs that genuinely benefit humanity.

What’s genuinely new here is the national security scope. The National Labs run a comprehensive nuclear security program focused on reducing the risk of nuclear war and securing weapons worldwide. OpenAI calls this use case “highly consequential” and says its researchers with security clearances will provide AI safety consultations and review use cases. The company already worked with Los Alamos on assessing whether advanced models could help create bioweapons — this agreement extends that collaboration across chemical, biological, radiological, and nuclear risks.

Microsoft is the quiet backbone of all this. The deployment happens through Microsoft as OpenAI’s preferred compute partner, and Venado itself was purpose-built for scientific breakthroughs in renewable energy, astrophysics, and materials science. It’s a three-way handshake — OpenAI provides the models, Microsoft provides the infrastructure, and the government provides the mission. Whether this accelerates actual discovery or primarily normalizes AI inside the national security apparatus is the question worth watching. Either way, it’s a signal that the AI race and the arms race are no longer separate conversations.
