Because Los Alamos National Laboratory required extremely high security and clearance for national security research, OpenAI could not deploy its models through standard APIs and instead built a custom on-prem deployment, physically installing the o3 model's weights onto the lab's air-gapped Venado supercomputer.
Sherwin Wu recounts how strict government security clearance requirements forced OpenAI to physically install its o3 reasoning model onto Los Alamos's air-gapped Venado supercomputer rather than provide standard API access. ✦ AI generated

“I know you had one as well.”
Because they are so, they're a government lab, they're so, you know, restrictive and high security and high clearance with a lot of their things, we couldn't just do a normal deployment with them. They couldn't, you know, you can't have people doing national security research just hitting our APIs. And so we actually did a custom on-prem deployment with them onto one of their supercomputers called Venado.

14:24very interesting about this one was that it's also a story of a very, like, bespoke and, like, new type of deployment that we've done. So because they are so, they're a government lab, they're so, you know, restrictive and high security and high clearance with a lot of their things, we couldn't just do a normal deployment with them. They couldn't, you know, you can't have people doing national security research just hitting our APIs. And so we actually did a custom on-prem deployment
14:48with them onto one of their supercomputers called Venado. And so this actually involves a bunch of, you know, very bespoke work with some FDEs, also with a lot of our developer team, to actually bring one of our reasoning models, o3, into their laboratory, into an air-gapped, you know, supercomputer Venado and actually deploy it and get it installed to work on their hardware, on their networking stack, and actually run it in this particular environment. And so it was
15:16actually very interesting because we literally had to bring the weights of the model physically into their supercomputer in an environment, by the way, where you're not allowed to have, you know, it's very locked down for a good reason. They're not allowed to have cell phones or like any electronics with you as well. So I think that was a very unique challenge. And then the other interesting thing about this deployment is just how it's being used, right? So the interesting
15:39thing is because it's so locked down and on-prem, we actually do not have much visibility into exactly what they're doing with it, but we do have, you know, they give us feedback. Yeah, yeah. They actually do have some telemetry, but it's, you know, within their own systems. But we do know that it's, you know, being used for a bunch of different things is being used for aiding
15:59them in terms of speeding up their experiments. They have a lot of data analysis use cases, a lot of notebooks that they're running with reams of data that they're trying to process. They're actually using it as a thought partner, which is something that's pretty interesting to me. o3 is like pretty smart as a model. And a lot of these people are tackling really tough, you know, novel research problems. And a lot of times they're kind of using o3 and going back and forth
16:20with it on their experiment design on like what they actually should be using it for, which is, you know, something that we couldn't really say about our older models. And so, yeah, it's just being used for a lot of different use cases for the National Lab. And the other cool thing is it's actually being shared between Los Alamos and some of the other labs, Lawrence Livermore, Sandia as
- ·Los Alamos requires extreme security and clearance for its research
- ·National security work could not be routed through OpenAI's public APIs
- ·OpenAI shipped the o3 model's weights directly to the lab
- ·The model runs on Los Alamos's air-gapped Venado supercomputer
