(Preview) Microsoft’s Plan for Platform Survival, Meta and the Market’s Permission, A Lack of Situational Awareness

Andrew SharpBen Thompson

Podcast
TL;DR
  • Microsoft gained 15% and $450 billion in one day as the market rewarded a strategy built around serving, rather than leading the creation of, frontier models. Ben Thompson’s framing: Microsoft keeps OpenAI’s inference business while training capacity moves elsewhere, then positions itself as the trusted enterprise layer between customers and OpenAI or Anthropic.
  • The hyperscaler risk gradient runs from Amazon’s physical infrastructure to Microsoft’s exposed software franchise: “The more physical you are, the safer you are. The more digital you are, the more threatened you are.” Google combines frontier ambitions with threatened search; Meta lacks a cloud business but faces a less acute threat from AI consuming users’ time.
  • Microsoft’s model is IBM in the 1990s: accept that monopoly-era scale weakened product excellence, then turn breadth, consulting and incumbent relationships into the advantage. As Lou Gerstner’s logic is paraphrased, “What we’re good at is being big” — a playbook that gave IBM another 20 to 25 years.
  • Microsoft wants to reduce frontier models to processors: stateless components beneath a Microsoft-provided or customer-built orchestration layer, analogous to Intel or AMD chips beneath Windows. The pitch is defensive but coherent — keep proprietary workflows and metadata away from model companies that otherwise learn “how people actually do work” and may eventually replace the software above them.
  • The strategic risk is timing: early technologies reward integration because they are “not good enough,” while modular suppliers tend to win later. Enterprises going directly to OpenAI or Anthropic might accept lock-in yet move so much faster that Microsoft’s multi-model harness becomes a lowest-common-denominator constraint.
  • Ben’s own experience sharpened that risk: scaffolding that helped model 5.5 on extra high became counterproductive with 5.6 because the newer model had internalized more planning and review. Meanwhile, the industry’s open letter signals fear, not strength: “You don’t sign open letters because you’re winning,” and NVIDIA could face margin compression if OpenAI and Anthropic become the only meaningful chip buyers.
Digest · the substance, structured for research

1. Microsoft’s rally masks the AI threat to its software franchise

  • Andrew Sharp opens with the market verdict: Microsoft rose 15% in one day, adding $450 billion — Bloomberg’s reported biggest single-day value increase in market history — despite having stepped away from the frontier-model race.

  • Ben maps the hyperscalers by cloud position, frontier ambition and AI exposure. Amazon sits at the safer extreme because “AI is not delivering my packages”; its e-commerce core is arguably better than ever, its cloud business is doing well, and its comfort with tighter margins may help if compute margins compress. Google has cloud and frontier models but threatened search; Meta lacks cloud, pursues the frontier and is less directly exposed than Microsoft.

  • The durable rule is physical versus digital exposure: “The more physical you are, the safer you are. The more digital you are, the more threatened you are.” Microsoft has Azure, but its productivity software can increasingly be recreated; Ben and Andrew’s team already replaced a narrow Teams-based podcast workflow with software they made themselves.

2. Microsoft is replaying IBM’s survival strategy

  • Ben’s analogy reaches back to IBM in the 1990s, when investors wanted the conglomerate broken apart. Lou Gerstner’s contrarian answer was that the pieces would struggle independently: “We’re not actually good at anything.… What we’re good at is being big.”

  • IBM converted breadth into 20 to 25 extra years by becoming the company enterprises trusted to navigate the internet, building consulting capacity and middleware for websites and e-commerce. Microsoft can similarly combine its sales force, forward-deployed engineering and decades-long customer relationships.

  • The uncomfortable premise is that a former monopoly may have “lost the ability to be great” after becoming “fat and flabby.” Microsoft therefore wins less through singular product leadership than by being acceptable across everything — precisely why Nadella’s earlier shift from Windows toward cloud and services mattered.

  • Nadella’s unusually personal control of the Build keynote suggested urgency to Ben: “We’re actually in bigger trouble than people realize.” Technology threats take years to reach reported results — as Intel’s problems took roughly a decade to manifest — but by the time the damage appears in the results, “it’s way too late.”

3. The real battle is ownership of enterprise workflow data

  • Ben remains skeptical that models truly generalize: “I don’t see evidence of generalization yet.” But that question might be moot because enough task data, feedback and verifiable outcomes can teach systems to perform increasingly broad categories of work.

  • Using Claude Code, Cowork, Codex or another model-company harness exposes more than prompts. Even if training data is excluded, the provider sees which tools workers use, what succeeds and what fails — “the crown jewels of your company,” because that metadata describes how the business actually operates.

  • Microsoft’s counterproposal is to make models resemble Intel or AMD processors beneath Windows: send each model only the context required for one computation, receive the result, and keep orchestration in a Microsoft-provided or customer-built harness. Microsoft wants stateless models; OpenAI and Anthropic are “trying to be everything.”

4. Integration could beat Microsoft before modularity arrives

  • Ben calls Microsoft’s strategy logical, especially for enterprises that want model choice and do not want to surrender proprietary context. But Clayton Christensen’s framework cuts against it initially: when technology is still inadequate, integrated solutions win because controlling more layers improves performance.

  • Microsoft benefits from the argument that models are very expensive and workloads require routing among cheap and costly options. Ben says that narrative felt “a little astroturfed,” because model capability can be more of a ceiling than a floor: a highly capable model can still answer an easy question quickly.

  • Andrew notes that enterprises may ultimately choose between paying Microsoft and paying OpenAI or Anthropic as a platform. Ben’s counter-scenario: a company going all-in with a frontier provider could accept lock-in yet accelerate so much faster that a cautious rival’s products simply “suck compared to yours.”

  • The unresolved issue is whether the harness itself matters. Microsoft benefits if models absorb most intelligence and orchestration becomes interchangeable; it loses if its controls withhold useful context, over-engineer the workflow and leave customers “not even coming close” to the models’ capabilities.

5. Model progress is erasing scaffolding while incumbents signal fear

  • Ben’s concrete example began with 5.5 on extra high, supplemented by a “Superpowers” skill package enforcing planning and review. With 5.6, which already overdid those behaviors, the same scaffolding became “out of control”: the improved model had internalized work previously performed by the harness.

  • A harness called Pie offered the corresponding design principle: do the minimum and add only necessary tools. Otherwise, work built around today’s limitations becomes harmful three months later because “your harness is competing with your model.”

  • The industry’s open letter reads to Ben as evidence of alarm over OpenAI and Anthropic’s uptake. Even OpenAI signed — especially revealing because it does not want open-model competitors — but the broader signal is categorical: “You don’t sign open letters because you’re winning.… You sign open letters ’cause you’re freaking terrified.”

  • NVIDIA’s participation reveals the economic stakes. If only two companies — OpenAI and Anthropic — meaningfully buy chips, NVIDIA becomes the supplier being ordered around, hyperscalers become financing vehicles, and margins compress; if successful startups can be replaced within a year or two, Ben asks whether a durable startup ecosystem remains at all.

Andrew Sharp

Hello, and welcome to a free preview of Sharp Tech. Hello, and welcome back to

Ben Thompson

We are in person. This is Sharp Tech.

Andrew Sharp

Welcome back to Sharp Tech.

Ben Thompson

And when I get the-

Andrew Sharp

Here we are

Ben Thompson

... when I get the Zoom open or Riverside open, cracks me up every time. How are you Anthony?

Andrew Sharp

Live and in person. I'm good. It's great to be in Madison. It's balmy outside relative to what it was in January, and we're here for some company meetings. There's an AI show-and-tell that we have planned that I'm already pretty stressed out about.

Ben Thompson

Because you have no AI in your life. Are you going to demonstrate looking up NBA stats?

Andrew Sharp

Yeah, demonstrate copy editing, Sharp text posts, and whatnot. You guys are on a whole other level. We're also going to a Brewers game later today, which I'm very excited about. It will be my first baseball game in probably 5 or 6 years. So here we are.

Ben Thompson

Well, you just asked me, "Are we going to tailgate?" and I was just flabbergasted.

Andrew Sharp

A total noob East Coast elite question. Of course we'll be tailgating.

Ben Thompson

It's funny, we were just talking about tailgating on Dithering, and I was expressing how East Coasters say they tailgate, and I find it very underwhelming. In D.C., they don't even bother, so it's good to know.

Andrew Sharp

Don't even bother; just show up at game time. Absolutely. Well, for now, before the tailgate, we're going to review big tech earnings, which came down last week, and we're going to start with 2 companies that are encountering very different reactions from the market.

First up is Microsoft. The market is very happy with Microsoft. The company was up 15% and added $450 billion in value in a single day last week—the biggest single-day jump in market history, according to Bloomberg. Microsoft is not pushing toward the frontier whatsoever at this point. They haven't been since 2024. What do you think of what they're doing instead?

Ben Thompson

If you zoom out, I knew earnings were going to be last week. I would come back, have all these things to digest, and I think all 3 updates this week were actually interconnected.

Andrew Sharp

Mm-hmm.

Ben Thompson

I argue we should have done 1 big post trying to tie them all together.

Andrew Sharp

An omnibus. Okay, yeah.

Ben Thompson

Yeah. I was trying to look at how every different hyperscaler is slightly different in where they are. Do they have a cloud business? Where are they relative to the frontier? What's their focus there, and what is their overall threat from AI?

So the 1 I didn't get into as much as I wanted to was Amazon. We're going to get to them in a little bit, but Amazon's on 1 extreme. They have a total cloud business, and I think their core business is not very threatened by AI.

Andrew Sharp

Yeah.

Ben Thompson

AI is not delivering my packages.

Andrew Sharp

Durable physical infrastructure for Amazon.

Ben Thompson

It's a good place to be. Yes.

Andrew Sharp

Yeah.

Ben Thompson

I think Amazon's core business, their e-commerce business, is fine—arguably better than ever. Their cloud business is obviously doing very well. Amazon is also a company that is more accustomed to, and okay with, tighter margins, which I think is 1 of the concerns about hyperscalers in the long run. Once compute is finally everywhere, who's going to have the best margins? Are margins going to compress? They've always thought about having lower-cost structures.

Andrew Sharp

They live in that world.

Ben Thompson

Right. We talked about that last episode. So Amazon is 1 extreme. Then you have Microsoft.

Andrew Sharp

Mm-hmm.

Ben Thompson

Microsoft is taking a strategy that's similar to Amazon in some respects, particularly in the fact that they're not on the frontier. They're building their own models, but they're not building models that are going to be as good as the models from OpenAI—

Andrew Sharp

Right.

Ben Thompson

—or from Anthropic. But they're serving those models.

Andrew Sharp

And they got off that train a couple of years ago with OpenAI.

Ben Thompson

They weren't really on that train. They were on that train to the extent that they were supporting OpenAI.

Andrew Sharp

Yeah.

Ben Thompson

But what happened—the way to think about what happened to Microsoft and OpenAI is, Microsoft said to OpenAI, "We'll keep your inference business."

Andrew Sharp

Mm-hmm.

Ben Thompson

"So the business where it's actually customers using your models—your training business—you've got to go find someone else."

Andrew Sharp

Yeah.

Ben Thompson

And so that was the whole shift to talking to Oracle, talking to SoftBank, and building these mega data centers. That's the train that they got off of.

Their software business is, I think, very threatened by AI.

Andrew Sharp

Mm-hmm.

Ben Thompson

We're going to talk about vibe coding a little bit. This will be part of the AI show-and-tell, but we are not representative of a large enterprise, to say the least. There's an aspect of us experimenting with AI Astrotechery that's important just to understand the product.

Andrew Sharp

Yeah.

Ben Thompson

But in a very tangible example, we were mostly still using Teams for 1 specific use case, which was podcast workflows. We're totally off it.

Andrew Sharp

Mm-hmm.

Ben Thompson

We made our own software, right? Now, again, that's a very small example, but you could imagine that writ large—

Andrew Sharp

Sure.

Ben Thompson

—at least in the fullness of time. So they have a cloud business that in some respects is similar to Amazon, but they have a core business that is very much threatened.

Andrew Sharp

Mm-hmm.

Ben Thompson

You move over, and now we're at Google. Google obviously has a big cloud business. I'm sure we're going to talk about that in a little bit. They are also seeking to be on the frontier, and they do have a business that's threatened by AI, which is search generally. We've spent a lot of time talking about that.

I think there's more to say about it than I wrote about this week in that regard, or than I mentioned in passing. So we'll talk about Google in a little bit, but they're kind of in the middle.

Then you get to Meta. Meta is maybe between Amazon and Google in that they're seeking to be on the frontier. They don't have a cloud business; that's the difference. They are threatened by AI, but I think less acutely—

Andrew Sharp

Than Microsoft.

Ben Thompson

—than Microsoft or even than Google.

Andrew Sharp

Yeah.

Ben Thompson

Right? You can see very clearly how AI is a threat to search.

Andrew Sharp

Mm-hmm.

Ben Thompson

It's harder to see how AI is a threat to social networking—

Andrew Sharp

Social networks, yeah.

Ben Thompson

—or entertainment, or whatever it is. But my thesis is, number 1, it takes up a lot of time—

Andrew Sharp

Mm-hmm.

Ben Thompson

—which is a detraction. So anything that takes up time is a detraction from Meta in the long run.

My overall thesis is that anything digital is fundamentally threatened by AI.

Andrew Sharp

Yeah.

Ben Thompson

The opposite of the Amazon thing: The more physical you are, the safer you are.

Andrew Sharp

Mm-hmm.

Ben Thompson

The more digital you are, the more threatened you are. That's the gradient of these entities.

I thought it was interesting to talk about all 4 of them this week, considering those aspects, even if I wasn't super explicit about it, and what the differences are between them, how the market has responded to them, and all these bits and pieces. So that's the overall context of Microsoft—

Andrew Sharp

Where we're at, yeah.

Ben Thompson

Yeah, and Microsoft in this case.

Andrew Sharp

With Microsoft specifically, they want to be middleware. Is that right? And to what extent is that a function of necessity, because that's the only option that makes sense for them at this point?

Ben Thompson

Yeah. The way to think about Microsoft is exactly that. It's funny because I wrote an article a few years ago comparing Microsoft to IBM.

Andrew Sharp

Mm-hmm.

Ben Thompson

It's actually 1 of my favorite articles. Some articles stand out because they were so painful to write. I remember I wrote this 1 at an Airbnb in Madison before we had a place here. It took me hours to get it out, and I posted it at about 3:00 in the afternoon instead of 6:00 in the morning, when I wanted to.

Andrew Sharp

Oh, boy.

Ben Thompson

I went through Lou Gerstner, who says "elephants can't jump," or something like that. It was his autobiography. I was talking about the issue IBM faced in the '90s, where they're this behemoth that seems way behind the times. Investors are demanding they break up.

He went the opposite direction. He's like, "We should not break up. You don't understand. We're not actually good at anything. So all these pieces you want independent are not going to do well in the market."

Andrew Sharp

They'll all fail independently. Sure.

Ben Thompson

"What we're good at is being big."

Andrew Sharp

Mm-hmm.

Ben Thompson

Actually, being big is useful because you're kind of good at everything, but you're not really great at anything.

Andrew Sharp

Okay.

Ben Thompson

Or you're acceptable at many things.

Andrew Sharp

Yeah. That certainly describes my Microsoft experience over the last 20 years.

Ben Thompson

This was IBM in the '90s. The internet's coming along. You have all these big companies that are like, “How do we handle—what do we do with the internet?” And IBM was like, “We'll take care of it.”

What IBM did was build up a huge consulting arm, which, by the way, Microsoft talked a lot about building up. They actually had a name for it. They've always had a big sales force, but the whole forward-deployed engineer thing. I should look up what the name was. It came up on the earnings call.

Andrew Sharp

That does make a lot of sense for the next 10 or 15 years here.

Ben Thompson

Well, everyone's doing it for good reason, right? Palantir really has led the way here. And then they also built a bunch of middleware.

Andrew Sharp

Mm-hmm.

Ben Thompson

Basically, they built all these layers for companies to have websites and e-commerce and all these bits and pieces that we talked a bit about last week. There are still companies that are on IBM because they've been on there since the '60s. There are a lot of companies that have been with IBM since the '90s because they just built in all these layers to get you online, to get you all the things that you needed to do that, and it was a very smart strategy that basically gave IBM an extra 20 or 25 years of life.

Andrew Sharp

Yep.

Ben Thompson

And the framing of that article was: once you've been a monopoly, you've kind of lost the ability to be great.

Andrew Sharp

Okay.

Ben Thompson

Because you get fat and flabby, and life's too easy. And what Lou Gerstner did was realize, “Look, we don't have the chops to succeed by being the best at any individual thing. What we're good at is doing everything because that's what we've been doing for a long time.” The analogy there was: look, this is the Microsoft path. You're not going to succeed by being the best at stuff.

Andrew Sharp

The leader in any area.

Ben Thompson

You can do everything, and it's good—actually, being big is your biggest asset.

Andrew Sharp

Yeah.

Ben Thompson

And I put that in the context of having been, at that point, a strong endorser of Satya Nadella's approach to deprioritizing Windows and turning it into a services layer. Yes, they were late relative to Amazon, late to the cloud, but most everyone else was late to the cloud. So they and all their customers were coming to the cloud together.

I wrote that in the context of a keynote where he spent a long time talking about pen or whatever, their digital ink, their ability. I was like, “What are you talking about?” You are not going to win on product differentiation. You're going to win by being good at everything, and I think Microsoft has continued down that path by and large. You fast-forward to AI, and now that comparison, I think, is becoming very, very tangible.

Andrew Sharp

Okay.

Ben Thompson

So Satya Nadella's been posting on Twitter all these articles. It's like he's coming for my job these days.

Andrew Sharp

I know. You said a couple of weeks ago he's coming for your job. He really is. He's very, very active on Twitter with these essays that he's putting out, and they're always these long tweets, and I wish he would put them on a website somewhere because I just can't read that much on Twitter. But he's clearly spooked by the moment and trying to counter the Anthropic messaging.

Ben Thompson

Yeah. I get the sense that spooked happened maybe a year or so ago. One thing that was interesting: I was at the Build keynote in June. Usually, at a Microsoft keynote, Satya Nadella would do the first 10 or 15 minutes, frame what's going on, and then hand it off to a parade of executives who would do the rest of the keynote. This keynote was all Satya Nadella.

Maybe I over-indexed, but part of my take this week is that I'm right to index on the meta of these things: what executives say actually matters.

Andrew Sharp

Mm-hmm.

Ben Thompson

What I took away from that keynote is that he felt the need to say, “I need to take a much firmer hand and much more control of this company, because we're actually in bigger trouble than people realize.”

Andrew Sharp

Yeah.

Ben Thompson

And I suspect a lot of it was that they have this whole software business, right? You can make the software that Microsoft does.

Andrew Sharp

Mm-hmm.

Ben Thompson

Now, are you going to make it—

Andrew Sharp

We just did.

Ben Thompson

Are you, are you going to make it actually useful and dependable, and are companies going to want to waste time maintaining it, et cetera, et cetera? All these are open questions, and we've litigated that, and we'll continue to litigate it probably for years to come. But Anthropic and OpenAI are coming for Microsoft's business.

Andrew Sharp

Mm-hmm.

Ben Thompson

Day-to-day productivity: they want your agent to do all that. They want your agent to do your email, your agent to do your documents. Why do we have documents? Why can't we just ask the AI what it is, right?

Andrew Sharp

Yeah. They're both very, very expensive for enterprises as well. And as those costs continue to rise, you could envision a future where enterprises are choosing between spending on Microsoft or spending on OpenAI as a platform or Anthropic as a platform.

Ben Thompson

Right. This is the thing about tech in general. Even right now, when stuff seems to be moving so quickly, one of the fun things about analyzing tech is how many decisions actually take years to play out. We've talked about this in the context of chips, right? Intel was doomed. I wrote in 2013, “Intel's in big trouble.”

Andrew Sharp

Took a solid 10 years.

Ben Thompson

Yeah. It took 10 years for that to actually manifest, but it was totally right. Intel actually needed to make changes. I thought I was too late in 2013, and I was, I think, too late. But it would've been better to make changes in 2013 than to wait until 2021 or whatever.

Andrew Sharp

Yeah.

Ben Thompson

Pat Gelsinger ripped the Band-Aid off. Again, there are pluses and minuses to his tenure, but he certainly ripped the Band-Aid off and said, “We have to shift our model over time.” But this applies to software too. By the time your business is threatened—or it shows up in the results—it's way too late.

Andrew Sharp

Mm-hmm.

Ben Thompson

And so I got that sense from Nadella. What he's been talking about in his blog posts is a bit of both: an articulation of the threat to Microsoft and trying to convince everyone else, “This is a threat to you as well.”

Andrew Sharp

Totally.

Ben Thompson

These companies are trying to understand your business. They're trying to figure out what you actually do with your computer.

Andrew Sharp

And they will replace you.

Ben Thompson

So they can replace you.

Andrew Sharp

Yeah.

Ben Thompson

This gets to the question of—

Andrew Sharp

It's explicit counter-messaging relative to—

Ben Thompson

Oh, for sure.

Andrew Sharp

Anthropic. Yeah.

Ben Thompson

But one of the big things with the AI models, and the question that remains open in my mind, is: will these models generalize? Can you learn one thing and then know how to do other things? I'm on the “I don't see evidence of generalization yet” side.

Andrew Sharp

Mm-hmm.

Ben Thompson

There's all this amazement about these math discoveries, right? Math is like coding. It's a knowable thing. You're discovering things that exist, but it's a bounded space to an extent, in a way that maybe some other things aren't. What you need to do is get data, see what works, and verify whether it worked or did not work. So at the end of the day, it might be a moot question.

Andrew Sharp

Mm-hmm.

Ben Thompson

Maybe you don't generalize; you just gather data on everything in the world, right? We'll get neural links in everyone's head and gather the thought processes, and then we'll actually be able to do everything. But this is the threat: we know for sure that if you can get enough data and verify, then you can do it.

Andrew Sharp

Mm-hmm.

Ben Thompson

And that's the threat he's putting his finger on. The more you use OpenAI or Anthropic and use their harness—you use Claude Code, you use Cowork, you use Codex—the more they're gathering everything. And even if they're saying, “Oh, we're not using your data to train the model,” that's actually not the important part. The important part is all the metadata around it. What tools are you using? What things worked? What things didn't?

Andrew Sharp

Mm.

Ben Thompson

And if you're using their user-facing software, you're giving away the crown jewels of your company, which are how people actually do work, what works, what doesn't, all the metadata around—

Andrew Sharp

You're training the disruption threat that—

Ben Thompson

That's right.

Andrew Sharp

Yeah.

Ben Thompson

That's right. And so what Microsoft is proposing to do is reduce models to being processors.

Andrew Sharp

Mm-hmm.

Ben Thompson

They want to recreate the world where Microsoft Windows is the layer everyone uses, and underneath that is an Intel chip, an AMD chip, or whatever it might be. What does that chip do? It gets sent stuff by the operating system, does some processing, and sends something back. It's the operating system that's the orchestrator, figuring everything out and passing things to developers on top of that.

Microsoft is saying, “Don't use their harnesses. We're going to build a harness, or we're going to give you the tools to build your own harness, such that these models are basically stateless.”

Andrew Sharp

Mm-hmm.

Ben Thompson

They're just things you send something to and get something back from, and they have no other context. All they get sent is exactly what they need to know to do a computation, and then it comes back. They're very explicit about it. That's what they're seeking: to reduce the model companies to being processors.

The model companies are trying to be—

Andrew Sharp

Everything.

Ben Thompson

—everything.

Andrew Sharp

Right.

Ben Thompson

And so that's the direct confrontation that's going on.

Andrew Sharp

Yes. When you look ahead, is this the right strategy for Microsoft? It may not work.

Ben Thompson

Well, this is where it's interesting to put Microsoft in contrast to Meta.

Andrew Sharp

Okay.

Ben Thompson

How do you survive in a world where you're not on the frontier?

Andrew Sharp

Mm-hmm.

Ben Thompson

What they're saying is, “We will be the layer between the frontier, where you can choose—”

Andrew Sharp

You don't have to worry about the models. It's going to be model-agnostic. You have your own harnesses with us, and you don't have to fork over proprietary data that puts your business at risk.

Ben Thompson

That's right.

Andrew Sharp

It makes sense.

Ben Thompson

I think it makes sense. It's a very reasonable strategy. The question, and I think the challenge for Microsoft, is most fraught right now because in any new technology, it doesn't work well enough, right? The AI still isn't good enough for a lot of these workflows.

The more you integrate and the more you do all the pieces around it, the better the stuff works. This is classic Clayton Christensen theory about integration versus modularization. The idea is that early on in a technology's life cycle, it's not good enough, so the more you do, the better. The integrated solution wins at the beginning.

In the long run, modularization takes over, where you want different suppliers and you care about competing on parts.

Andrew Sharp

You care about cost, yeah.

Ben Thompson

There was a huge wave of, “Oh, these models are so expensive.” That felt a little astroturfed over the last few months, to be totally honest.

Andrew Sharp

Hmm.

Ben Thompson

That is a narrative that Microsoft absolutely wants to feed, because they want you thinking, “We can't double down.”

Andrew Sharp

“We can't burn through the budget in 2 months on these models.”

Ben Thompson

That's right.

Ben Thompson

And so you think about it: “A harness is good because we can use different models. You can do sort of an X, Y, Z.” It's kind of funny because I'm not sure how much I buy the multimodel idea. If you ask a really smart model a very easy question, it's going to give you a very quick and fast answer, right?

Andrew Sharp

Mm-hmm.

Ben Thompson

A lot of the model capability is more of a ceiling than it is a floor.

Andrew Sharp

Good point, yeah.

Ben Thompson

There's an aspect here where it feels like Microsoft loves the “expense, use lots of models, expensive models, cheap models” narrative, because that fuels the question, “How do I do that?” Well, you need a harness, right? You need a harness that has a router that chooses the right model for the job.

Andrew Sharp

And they're the harness company at this point.

Ben Thompson

There are cost differences, to be clear. I'm not trying to overstate or underplay that. But it also is a narrative that feeds what Microsoft wants people to think.

Andrew Sharp

Mm-hmm.

Ben Thompson

You can't build directly on these. On the flip side, a lot of companies are going to find this appealing. They don't want to try to figure all this out. It's like the cloud: Microsoft's their good friend. What's going on here?

Andrew Sharp

Exactly.

Ben Thompson

Figure it out.

Andrew Sharp

They've been working with Microsoft for 35 years at this point.

Ben Thompson

Right. There's also a question, though: How much better is it actually if you're working directly with the frontier model companies?

Andrew Sharp

Right.

Ben Thompson

Can you actually build stuff that you can't build otherwise? Can that stuff actually accelerate your business such that your competitor is so worried about having multiple suppliers and not getting locked into the model companies that their products suck—

Andrew Sharp

Mm-hmm.

Ben Thompson

—compared to yours because you gave in? You're like, “That's right, I'm all in on OpenAI, or I'm all in on Anthropic, and I'm so much faster and accelerating so much more quickly.” And, oh, by the way, they have this feedback loop that's actually extending their lead.

The idea is that Microsoft is going to be making a harness that is lowest-common-denominator functionality—

Andrew Sharp

And is comparable to what Anthropic and OpenAI are offering.

Ben Thompson

That's right.

Andrew Sharp

Yeah.

Ben Thompson

Now, we'll see. I don't know, right? At the end of the day, does the harness actually matter that much?

Andrew Sharp

Yeah.

Ben Thompson

There's a thing where you can feel this with the models. When I started doing the vibe-coding stuff, it was with 5.5 on extra high.

Andrew Sharp

Mm-hmm.

Extra high? Okay.

Ben Thompson

No, for 5.5, not 5.6.

Andrew Sharp

Oh, okay, okay.

Ben Thompson

For 5.5, there was this Superpowers skill package someone put together that forced it to do this planning and this review, and someone recommended it to me. I was already doing planning and reviewing, but I still thought it was kind of useful.

You get to 5.6, which overdoes this stuff on its own.

Andrew Sharp

Mm-hmm.

Ben Thompson

You layer on this stuff, and it was out of control. Part of the reason it was out of control was that it was doing all this crazy stuff. Basically, the point is that as the models got better, they internalized more and more of the functionality that came from the harness.

Andrew Sharp

Right.

Ben Thompson

There's a harness called Pie. They had a really interesting blog post this week talking about their whole approach: to do the minimum amount necessary in the harness, and make it possible for you to add on the specific tools that you need.

Everyone's overengineering this such that 3 months down the road, a new model comes out and you're actually making the whole situation worse because your harness is competing with your model.

Andrew Sharp

Mm-hmm.

Ben Thompson

You did all this work upfront to overcome the model's limitations, but then the model got better. Why? It's all wasted effort, right?

Andrew Sharp

Right.

Ben Thompson

You should just let the model do everything.

It's funny, because that's a world that's actually—possibly—good for Microsoft.

Andrew Sharp

Mm-hmm.

Ben Thompson

If it's all about the model and it doesn't matter what harness you use, then, yeah, use Microsoft's harness. Use your harness.

There's also a world where Microsoft's harness is so overengineered and so careful to try to do things and not let the models get the data they need that they're not even coming close to tapping into what the models can do.

Andrew Sharp

Right.

Ben Thompson

The models would be better if you gave them way more stuff, right?

Andrew Sharp

You're gating the performance.

Ben Thompson

Yeah.

Andrew Sharp

Yeah.

Ben Thompson

All this stuff is kind of unknown. This was so interesting. I think what they're doing is logical. There are a lot of benefits that come from being the incumbent.

Andrew Sharp

Mm-hmm.

Ben Thompson

There's a reason why, as a technologist, you could ask, “Why would any company use IBM's solution to build a webpage in the 1990s?” And yet it worked phenomenally well.

Andrew Sharp

Lots of companies did.

Ben Thompson

Right?

Andrew Sharp

Yeah.

Ben Thompson

And so—

Andrew Sharp

Well, it will be interesting. Obviously, it's all sort of TBD, but you look at the number of companies that signed the open letter, for instance. You look at the weekly HFC series—

Ben Thompson

Oh, I didn't get a chance to write about the open letter on Stratechery.

Andrew Sharp

—from Satya.

Ben Thompson

Hilarious. That thing cracked me up.

Andrew Sharp

Well, it's clearly a reaction to massive uptake for Anthropic and OpenAI, and the concern that that inspires everywhere else to go down that—

Ben Thompson

Oh, and the funniest thing is OpenAI signing the letter.

Andrew Sharp

Oh, I didn't see that OpenAI signed it.

Ben Thompson

Oh, they did.

Andrew Sharp

That's wonderful.

Ben Thompson

The most two online company in history.

Andrew Sharp

Don’t worry, guys. We’re with you.

Ben Thompson

Yeah, we got it. My finger’s up in the wind. I guess we better sign the letter. Of course, they don’t want these open-model competitors.

Andrew Sharp

That’s fantastic.

Ben Thompson

But do you know what I mean?

Andrew Sharp

Like, that’s sort of an indication of the real concern.

Ben Thompson

For sure.

Andrew Sharp

Yeah.

Ben Thompson

The fact that the whole industry is lining up to sign this letter is not an indicator of strength for the companies signing the letter. You don’t sign open letters because you’re winning. You sign open letters because you’re freaking terrified.

Because you see these entities swallowing everything. They can do stuff you never expected, right? You see, you talk about Apple and Apple not seeing the memory crunch coming, as we’ve talked about. Or you see even this response. Has Tim Cook vibe-coded an app? I’m guessing probably not.

And I’m not saying you have to vibe-code an app to understand AI, but there is an extent to which what these models can do is so far beyond what I think most people—

Andrew Sharp

Can appreciate.

Ben Thompson

—really understand.

Andrew Sharp

Yeah. Sure.

Ben Thompson

But someone like Satya Nadella gets it, right? And when you see this with NVIDIA, too—Jensen Huang, the sort of guy pushing this letter, is important enough for him to get on Twitter, right?

Andrew Sharp

Exactly.

Ben Thompson

One of the worst decisions a human can make.

Andrew Sharp

Well, to the extent that we lack perfect visibility into how enterprises are using these tools today, I think the reaction from the incumbents across tech—the non-Anthropic and OpenAI incumbents—says a lot about what companies are using these things for.

Ben Thompson

Right. So NVIDIA feels like they’re in the catbird seat, right? Everyone uses NVIDIA chips. Why are they writing an open letter? Because in a world where there are only 2 companies that buy chips—

Andrew Sharp

Yeah.

Ben Thompson

—NVIDIA’s the one that gets ordered around.

Andrew Sharp

Margins get compressed.

Ben Thompson

Yes.

Andrew Sharp

Right.

Ben Thompson

They will have the scale, the capability, and the cash flow to make their own chips. And it’s the same thing for all the hyperscalers.

Andrew Sharp

Yeah.

Ben Thompson

In a world where there are only 2, and all you’re doing is competing to serve OpenAI and serve Anthropic, those margins are going to get compressed a lot.

Andrew Sharp

Mm-hmm.

Ben Thompson

You’re just going to be a financing vehicle to help them build these sorts of things out. And so the whole question is, why are VCs in on this thing? Is there even a startup ecosystem if you just use the models to do everything?

Andrew Sharp

Every startup gets replaced within a year or 2 if it succeeds.

Ben Thompson

That’s right.

Andrew Sharp

Well, shifting gears, you wrote on Monday with respect to Meta that you came away from the Meta call a bit alarmed. So, on a scale of 1 to 10, how alarmed are you by the enterprise pitch from Meta? Or is annoyance a better way to put it with Meta?

Ben Thompson

So the Meta and Microsoft comparison, I think, is super interesting.
