On their latest collaboration, Microsoft boss Satya Nadella and xAI’s Elon Musk had a brief chat, shared by the duo on social media. Welcoming Grok onboard Azure, Nadella remarked, “Thank you so much, Elon, for being here at (Microsoft) BUILD.” He recalled how Musk gigged with the Bill Gates firm during the early days. “I know you started off as an intern at Microsoft,” he added. “You were a WINDOWS developer.” “Of course you are a big PC gamer still,” Nadella continued. He further invited Musk to walk through the memory lanes of his Microsoft days.

Musk quipped,

"Ah, yeah… I actually started before WINDOWS with DOS. I have worked on the earliest IBM PCs with MS-DOS. And it had, like, 128k in the beginning, which doubled to 256k, which is, like, a lot.”

He added,

"So I programmed video games in DOS. Then later in WINDOWS. Run WINDOWS 3.1.”

Nadella interrupted,

"Last time I chatted with you, you were talking about the intricacies of ACTIVE DIRECTORIES and it's fantastic to have you at our developer conference. Obviously the exciting thing for us is to launch GROK on AZURE."

He continued,

"I know you have deep vision for what AI needs to be and that’s what got you get this built. It’s a family of models that are both responsive and reasoning models. And you have a very exciting roadmap."

Nadella asked Musk,

"Tell us a bit about your vision as you are pushing on both capabilities and efficiencies."

The billionaire responded,

"GROK 3.5 is trying to reason from first principles. If you're tryna get to fundamental truths, then it boils down to axiomatic elements that are most likely to be correct, and reason out from there."

Musk continued,

"Focus of GROK 3.5 is fundamental physics and applying physics tools across all lines of reasoning and to aspire to truth with minimal error.”
