Full Interview

Host: Hello Sam, great to see you. I witnessed everything in Abilene—awesome, right? Let’s go back before the “Stargate” project. What made you realize we needed more compute, more capability, broader connectivity, and that we’d hit a limit requiring expansion?

Sam Altman: Initially we focused on the compute needed to train models, paying less attention to how users would actually use them. After GPT‑4 and ChatGPT launched, user demand far exceeded our expectations, highlighting the problem.

That demand has turned into what is now the largest‑scale infrastructure project in history. We began exploring how to achieve it and where the supply‑chain bottlenecks lie. “Stargate” emerged from that evolution, building on earlier smaller collaborations with partners like Microsoft.

Host: You’ve traveled the world meeting partners. How did you meet Masayoshi Son and Larry Ellison and secure cooperation?

Sam Altman: I’ve known Masayoshi Son for a long time. In 2023 I made two extended trips around the globe, often to understand the supply chain firsthand. During one trip I met Son, who has long thought about chip manufacturing and the broader industry layout. We discussed what massive compute would require, realizing it needed a complex supply chain, many partners, and huge capital.

Host: SoftBank is clearly a financial partner and Oracle a technical partner. Why can’t Microsoft meet all your needs?

Sam Altman: Microsoft provides massive support, but the scale of this project exceeds what any single company can handle. Microsoft will continue to supply huge compute capacity, which we appreciate.

Host: Why call it “Stargate”?

Sam Altman: It started as an internal code name that stuck.

Host: Does it have a special meaning?

Sam Altman: Early data‑center layout diagrams looked a bit like the sci‑fi series “Stargate”.

Host: You announced this at the White House. How was it presented to the President?

Sam Altman: The President is very interested in infrastructure and sees energy production and data‑center approvals as a priority. That’s how the conversation began.

Host: How will this affect future data‑center design?

Sam Altman: There’s still much to learn from chip to architecture, but the explosive growth in inference demand is the biggest focus. Our resources are stretched, even with a massive compute cluster.

Our products and services are always in excess demand. Beyond technical experience and future blueprints, the core issue is we simply need more compute.

Host: Explain the $500 billion figure. What does it cover?

Sam Altman: It reflects the compute capacity we’ll need based on growth forecasts for the coming years. If we could raise a trillion dollars now, we’re not sure we could deploy it profitably, but we believe the $500 billion investment will create value and eventually be recouped.

Host: You’ve recently raised more capital. How confident are you that OpenAI can become financially sustainable and profitable?

Sam Altman: Progress is strong; we’re doing unprecedented things. I’m confident in the investment, though it’s not a guarantee.

Host: You joked about GPUs “melting”. What’s the reality?

Sam Altman: It was a metaphor. GPUs run hot, but the metal parts don’t actually melt.

Host: When a product launch creates such a surge, what’s happening internally? How will “Stargate” alleviate this?

Sam Altman: The scale of growth is extraordinary—unprecedented in tech history. We’ve seen massive user spikes that no company has ever faced.

Host: You’ve added millions of users in an hour. Is that true?

Sam Altman: At certain times, yes. The growth is insane, especially for image generation, which is compute‑intensive. We’ve had to reallocate compute from research, delay some feature iterations, and limit usage because we don’t have idle GPUs.

Improving efficiency helps, but ultimately more compute means stronger AI for users to generate images, write code, etc.

Host: Elon Musk’s xAI claims Grok is the smartest AI. Your thoughts?

Sam Altman: I don’t use it much, but many good models will become widespread.

Host: What is OpenAI’s advantage?

Sam Altman: Our advantage lies in infrastructure and top‑tier application experience. ChatGPT’s user base far exceeds any other AI service, and we’ll continue to strengthen that lead.

Host: Once the infrastructure is built, what is your grand vision?

Sam Altman: To empower people with powerful tools that improve work and creativity. AI is a new tool that will unlock creativity and drive scientific breakthroughs.

Personally, I’m most excited about AI’s role in accelerating scientific discovery.

Host: Will you deploy “Stargate” data centers on every continent?

Sam Altman: You’ll see them on other continents, though not everywhere, and I don’t know the exact locations.

Host: How do you view the influence of chip makers like NVIDIA?

Sam Altman: NVIDIA makes incredible products; market demand follows excellence, giving them huge influence.

Host: AI will reshape employment—some jobs will disappear, new ones will appear. What do you say to those anxious about this?

Sam Altman: Technological change always alters job structures. Some roles vanish, many new ones emerge. The pace may outstrip society’s ability to adapt, but this is a normal historical pattern.

The speed of change is unprecedented, and the world isn’t fully prepared for the impact of humanoid robots and AI on daily life.

We continue to communicate our expectations honestly, while recognizing we may make mistakes.

Host: When humanoid robots become common, what will the world look like?

Sam Altman: You’ll see dozens of robots bustling around, performing various tasks—a truly sci‑fi scene.

Host: Does DeepSeek’s more efficient AI method make you rethink your approach?

Sam Altman: DeepSeek is talented and has great results, but I don’t think they’ve found a more efficient path than ours.

Host: Why keep building such massive infrastructure if efficiency keeps improving?

Sam Altman: Even if AI costs drop to a tenth, usage could increase twenty‑fold, still requiring double the current compute capacity.

Host: How does the Jevons paradox apply here?

Sam Altman: It’s not really a paradox; increased consumption is just how technology works.

Host: Will AI accelerate scientific discovery?

Sam Altman: Absolutely—AI will dramatically speed up scientific exploration and expand the boundaries of what’s possible.

Host: Is the future bright and happy?

Sam Altman: There will be ups and downs, not perfect, but the overall trend is positive.
