Elon Musk and OpenAI posture over pizza as the AI talent war heats up

• Elon Musk and an OpenAI engineer postured about free pizza over the weekend in recruitment posts.
• Musk touted xAI's wood-fired pizza; the OpenAI engineer touted their dough and campus chef.
• The exchange comes as tech companies compete for top AI talent — and cancel other perks amid broader cost-cutting.

The rivalry between xAI and OpenAI is heating up again — this time, over wood-fired pizza.

Over the weekend, Elon Musk and an OpenAI engineer jockeyed on X about wood-fired crusts, dough fermentation, and campus chefs.

On its face, it was a lighthearted back-and-forth about free pizza for lunch. Underneath, it encapsulates a trend playing out in Silicon Valley: rival AI companies are publicly pitching culture — and perks like free lunch — in the talent war for top engineers.

The exchange began when Musk reposted a video of an xAI engineer calling his job the "opportunity of a lifetime."

"Join @xAI," Musk wrote.

The post quickly drew a response from xAI's competitor, OpenAI.

"Or join Codex," said Thibault Sottiaux, an engineering lead working on OpenAI's Codex software agent, who is also hiring. OpenAI operates "with much of the same principles," he wrote — before adding an increasingly common recruitment pitch.

"Join the bright side, we have pizza," Sottiaux wrote.

Musk fired back: "But how good is your wood oven pizza?"

The pizza posturing then shifted to ingredients — and the corporate chefs preparing them.

"But how about the dough?" he wrote back. "Can't take shortcuts, needs 24 hours at least. And our chef is ????."

"Our chef is so good that God looked down at the food from heaven and said you my most delicious creation," Musk replied.

"And after having a bite, he wasn't 100% satisfied and asked our chef to improve upon the SoTA," Sottiaux said. "Our chef delivered, and created a recipe now universally credited to accelerating the AGI timeline."

The very real fight behind the pizza posts

The tomato pie-based banter was sweet — but the subtext was spicier.

AI labs are locked in a high-stakes dash for elite engineers, with high-end compensation packages stretching into the nine-figure territory.

Companies including Amazon, Microsoft, Meta, OpenAI, and Musk's xAI are competing for a relatively small pool of researchers capable of building the next generation of models and infrastructure.

Aside from money, two key perks have emerged in the AI talent wars, according to professional AI poacher Mark Zuckerberg: access to GPUs and fewer direct reports.

"People say, 'I want the fewest number of people reporting to me and the most GPUs,'" Zuckerberg said in 2025 TITV interview.

At the same time, the broader tech industry has pulled back on many of the pre-pandemic perks amid cost-cutting. Remote work has narrowed, layoffs have gathered steam, and perks like pet care stipends and expansive wellness benefits are becoming less common for new hires.

But there's one perk that has remained: the fancy lunch spread.

Might as well throw in wood-fired pizza, too.
