There are mornings in San Francisco when the light strikes office windows in a manner that makes everything appear sharper than it actually is. Conversations about technical updates, infrastructure, and product rollouts tend to flow swiftly within OpenAI’s headquarters, but there is a quieter layer somewhere in the middle. Not every one of them. Only a handful appear to be more important than the others.
The CFO of OpenAI, Sarah Friar, has been remarkably forthright about this. She concentrates on three key financial indicators in a field that is notorious for monitoring everything—engagement, impressions, and experimental features. It sounds easy. It most likely isn’t. Revenue is the first, but not in a vacuum. Compute capacity and annual recurring revenue, or ARR, are tightly related. It’s interesting because of that pairing.

The rate at which OpenAI’s revenue has increased feels nearly squeezed. from about $2 billion to more over $20 billion in a little period of time, coinciding with enormous increases in processing capacity. Energy usage is increasing, data centers are growing, and GPUs are stacking. It’s feasible that infrastructure, not just software, is the true foundation of the AI economy.
It seems like Friar is keeping a close eye on the relationship. Not only does revenue increase, but it also increases in proportion to the resources needed to produce it. due to the high cost of computing. Not even near.
As one moves through conversations about AI firms, one particular detail keeps coming up. Model training and operation are very expensive. It behaves differently from typical software, which can scale users at a comparatively minimal incremental cost. In this case, each extra layer—more queries, more intricate models—requires more hardware and energy. This brings us to the second metric: unit economics and margins.
It’s difficult to ignore how infrequently this is discussed in public inside the AI community. There is a lot of discussion about new models, capacities, and innovations. But less about the viability of those approaches in terms of money. Friar appears to be concentrating on that.
Although they aren’t very glamorous indicators, gross margins, cohort profitability, and cost per user all help decide whether expansion can continue without becoming unstable. Whether the current economics of AI can sustain long-term scaling at the rate businesses are seeking is still up for debate.
Investors appear to think that the need for AI will outweigh the expenses. The equation will eventually be balanced by new apps, premium pricing, and enterprise uptake. However, reality and belief don’t always coincide right away. This is where usage, the third metric, enters the picture.
active users every day. users who are active every week. Real involvement, not simply total sign-ups. usage that indicates people are incorporating these tools into their daily activities, workflows, and decision-making processes.
There’s a sense that something fundamental is changing when you see how rapidly usage has increased. AI tools are no longer sporadic experiments. They are being included into common systems, including as writing, coding, and analysis. However, utilization is insufficient on its own.
If the expense of supplying millions of users exceeds the revenue they bring in, it is feasible to have millions of users and still have financial difficulties. Friar’s emphasis on these three indicators feels linked because of this. Revenue is dependent on computation. margins associated with sustainability. Demand and usage are related.
Beneath these fundamental measures is another layer. Cost and lifetime worth of acquiring new customers. Though less obvious, they are equally significant. Particularly if OpenAI shifts more customers to its enterprise products, which have more intricate pricing structures.
It’s difficult to ignore how this strategy differs from previous stages of the tech sector. Growth used to frequently take precedence over profitability. Scale was supposed to be the answer in the end. That luxury might not be possible with AI.
Just the infrastructural requirements—data centers, energy use, hardware supply chains—introduce limitations that weren’t there previously. Scaling too quickly without considering expenses could lead to issues that are more difficult to resolve.
As this develops, it seems that Friar’s approach encompasses more than just OpenAI management. It may be an indication of how the AI industry as a whole will have to function. more realistic. more conscious of compromises.
When thinking about this change, one particular moment comes to mind. the notion of being “maniacal” about expenses, as Friar has put it. It implies a degree of discipline that seems almost inappropriate in a field that frequently relies on quick experimentation. But perhaps that’s just what’s required.
Because there is a deeper question that lies underlying the excitement surrounding AI—new models, new capabilities, and new applications.
