This is Bloomberg Tech. AI leaders are calling for a slower pace at the frontier. Anthropic CEO Dario Amadeus saying over the weekend, we must slow the pace at which we improve the capabilities of AI models. His argument, safety needs time to keep up. Open AI Sam Altman and SpaceX AI Elon Musk quickly backing the idea. Anthropic is now opening its doors to independent evaluators, while Altman says Open AI will not go public this year as it prioritizes safety.

This has prompted a response from President Trump this morning, saying in a true social post his administration has, quote, stopped AI people from doing bad things, and they will continue to do so. And the debates hitting markets, NVIDIA, Micron, other AI linked stocks, all under pressure, is investors ask what a slower frontier could mean for the AI spending boom. Throughout the hour, what pacing actually means, the industry response, and what comes next. From Washington, Bloomberg's AI reporter, Rachel Metz, and tech editor in DC, Mike Sheppard, join us for the details. Rachel, let's start with the essay from the philanthropic CEO, Dario Amadei, which was published this Saturday. What do we need to know?

Rachel Metz (1:29)

I mean, he's talking a lot about some of the wonderful things that AI can lead to, but also how recent events, such as an inadvertent hack by open AI models of hugging face, are leading to this moment where he believes that some sort of pacing is necessary in order to ensure safety of AI.

Ed Ludlow (1:49)

Shepp, you were on hand all weekend on duty to basically bring together all of the responses that came in. First, it was Sam Altman, then Elon Musk, and then lots of investors and politicians weighed in too. Try and summarize it.

Mike Sheppard (2:02)

Well, you know, quickly, we saw the arch rivals of Anthropic, Sam Altman from Open AI, Elon Musk from SpaceX AI, quickly embrace and broad terms. Dario Amadeus called for a slowdown. When you get into the specifics, it's a little bit unclear how closely aligned they all are, but on the broad strokes, they back it. Investors are a little bit skeptical about how far the companies will actually go in slowing this down. And for their part, Dario Amadeus and Sam Altman are insisting that slowing the pace at the frontier does not mean stopping spending or slowing down work or growth in their businesses.

Ed Ludlow (2:42)

There is no commitment to end training runs or reduce spending. I think that's really important. Rachel, I think it's worth going back over the timeline of the last seven days. When we started this story, it was because an anthropic researcher had resigned. And we also had reporting that Sam Altman, who's the CEO of OpenAI, had already gone companywide to say, we think we should slow the pace, fill the gaps.

Rachel Metz (3:06)

Okay.

So we had this resignation. It seemed to gain ground, it gained a lot of attention, just not just within AI, but also outside of AI. And then Sam Altman, as you mentioned, our reporting indicated that he had said that the company was interested in pacing and was hoping other companies would join as well. And then since then, we're just seeing this sort of snowball effect where we're getting more and more talking toward this idea of pacing. But as you guys both mentioned, it's not clear what that would mean. And it certainly doesn't include any commitments to actually slow down innovation internally, perhaps more externally. And also, they're talking about using some outside companies as well to look over their models and that kind of thing. So a lot of unanswered questions still, I would say.

Ed Ludlow (3:58)

We've had the reaction from the president this morning over the weekend, the reaction from Congress Democratic Senator Chris Coons of Delaware speaking to Bloomberg this weekend.

Mike Sheppard (4:06)

Now that we've got agreement from Elon Musk and Sam Altman and Dario Amadei, we need agreement from Republicans and Democrats in Congress to put aside our partisan pre-election bickering and put in place some real guardrails before AI goes off the rails.

Ed Ludlow (4:24)

Sheb, what's happening on Capitol Hill right now?

Mike Sheppard (4:27)

Well, there's a lot of talk, and we heard Chris Coons really lay out his vision for trying to get both parties together quickly before the election to find some consensus on this. But in a bitterly divided House and Senate, it's hard to imagine that they would be able to agree on something that's so technically difficult to wrap their heads around. In that interview, Coons also pointed to a relative lack of tech expertise on Capitol Hill. And then meanwhile, going down Pennsylvania Avenue, inside the Trump administration, we heard the president just now in social media really going after Dario Amadei directly over this call for guardrails, insisting that he as president is the best guardrail of all. And you look at this, stepping back for a moment, AI development is central to the president's economic agenda, and it's also critical to this upcoming meeting with Chinese leader Xi Jinping. The president, Donald Trump, has put AI at the center of the economic competition with China, and he doesn't want anything holding the US back in this moment.
