Who are they for? Delphi, a startup that recently raised $16 million from funders including Anthropic and actor/director Olivia Wilde’s venture capital firm, Proximity Ventures, helps famous people create replicas that can speak with their fans in both chat and voice calls. It feels like MasterClass—the platform for instructional seminars led by celebrities—vaulted into the AI age. On its website, Delphi writes that modern leaders “possess potentially life-altering knowledge and wisdom, but their time is limited and access is constrained.”
It has a library of official clones created by famous figures that you can speak with. Arnold Schwarzenegger, for example, told me, “I’m here to cut the crap and help you get stronger and happier,” before informing me cheerily that I’ve now been signed up to receive the Arnold’s Pump Club newsletter. Even if his or other celebrities’ clones fall short of Delphi’s lofty vision of spreading “personalized wisdom at scale,” they at least seem to serve as a funnel to find fans, build mailing lists, or sell supplements.
Via a helpful chatbot interface, Tavus walked me through how to craft my clone’s personality, asking what I wanted the replica to do. It then helped me formulate instructions that became its operating manual. I uploaded three dozen of my stories that it could use to reference what I cover. It may have benefited from having more of my content—interviews, reporting notes, and the like—but I would never share that data for a host of reasons, not the least of which being that the other people who appear in it have not consented to their sides of our conversations being used to train an AI replica.
So in the realm of AI—where models learn from entire libraries of data—I didn’t give my clone all that much to learn from, but I was still hopeful it had enough to be useful.
Alas, conversationally it was a wild card. It acted overly excited about story pitches I would never pursue. It repeated itself, and it kept saying it was checking my schedule to set up a meeting with the real me, which it could not do as I never gave it access to my calendar. It spoke in loops, with no way for the person on the other end to wrap up the conversation.
These are common early quirks, Tavus’s cofounder Quinn Favret told me. The clones typically rely on Meta’s Llama model, which “often aims to be more helpful than it truly is,” Favret says, and developers building on top of Tavus’s platform are often the ones who set instructions for how the clones finish conversations or access calendars.
For my purposes, it was a bust. To be useful to me, my AI clone would need to show at least some basic instincts for understanding what I cover, and at the very least not creep out whoever’s on the other side of the conversation. My clone fell short.
Such a clone could be helpful in other jobs, though. If you’re an influencer looking for ways to engage with more fans, or a salesperson for whom work is a numbers game and a clone could give you a leg up, it might just work. You run the risk that your replica could go off the rails or embarrass the real you, but the tradeoffs might be reasonable.
Favret told me some of Tavus’s bigger customers are companies using clones for health-care intake and job interviews. Replicas are also being used in corporate role-play, for practicing sales pitches or having HR-related conversations with employees, for example.
But companies building clones are promising that they will be much more than cold-callers or telemarketing machines. Delphi says its clones will offer “meaningful, personal interactions at infinite scale,” and Tavus says its replicas have “a face, a brain, and memories” that enable “meaningful face-to-face conversations.” Favret also told me a growing number of Tavus’s customers are building clones for mentorship and even decision-making, like AI loan officers who use clones to qualify and filter applicants.
Which is sort of the crux of it. Teaching an AI clone discernment, critical thinking, and taste—never mind the quirks of a specific person—is still the stuff of science fiction. That’s all fine when the person chatting with a clone is in on the bit (most of us know that Schwarzenegger’s replica, for example, will not coach me to be a better athlete).
But as companies polish clones with “human” features and exaggerate their capabilities, I worry that people chasing efficiency will start using their replicas at best for roles that are cringeworthy, and at worst for making decisions they should never be entrusted with. In the end, these models are designed for scale, not fidelity. They can flatter us, amplify us, even sell for us—but they can’t quite become us.
