Wild-Ass Guess (Ass-Guess) incoming:

OpenAI was built to influence the eventual value chain of AI in directions that would give the funding parties more confidence that their AI bets would pay off.

This value chain basically being one revolving around AI as substituting predictions and human judgement in a business process, much like cloud can be (oversimply) modeled as moving Capex to Opex in IT procurement.

They saw that, like any primarily B2B sector, the value chain was necessarily going to be vertically stratified. The output of the AI value chain is as an input to another value chain, it's not a standalone consumer-facing proposition.

The point of OpenAI is to invest/incubate a Microsoft or Intel, not a Compaq or Sun.

They wanted to spend a comparatively small amount of money to get a feel for a likely vision of the long-term AI value chain, and weaponize selective openness to: 1) establish moats, 2) Encourage commodification of complementary layers which add value to, or create an ecosystem around, 'their' layer(s), and 3) Get insider insight into who their true substitutes are by subsidizing companies to use their APIs

As AI is a technology that largely provides benefit by modifying business processes, rather than by improving existing technology behind the scenes, your blue ocean strategy will largely involve replacing substitutes instead of displacing direct competitors, so points 2 and 3 are most important when deciding where to funnel the largest slice of the funding pie.

_Side Note: Becoming an Apple (end-to-end vertical integration) is much harder to predict ahead of time, relies on the 'taste' and curation of key individuals giving them much of the economic leverage, and is more likely to derail along the way._

They went non-profit to for-profit after they confirmed the hypothesis that they can create generalizeable base models that others can add business logic and constraints to and generate "magic" without having to share the underlying model.

In turn, a future AI SaaS provider can specialize in tuning the "base+1" model, then selling that value-add service to the companies who are actually incorporating AI into their business processes.

It turned out, a key advantage at the base layer is just brute force and money, and further outcomes have shown there doesn't seem to be an inherent ceiling to this; you can just spend more money to get a model which is unilaterally better than the last one.

There is likely so much more pricing power here than cloud.

In cloud, your substitute (for the category) is buying and managing commodity hardware. This introduces a large-ish baseline cost, but then can give you more favorable unit costs if your compute load is somewhat predictable in the long term.

More importantly, projects like OpenStack and Kubernetes have been desperately doing everything to commodotize the base layer of cloud, largely to minimize switching costs and/or move the competition over profits up to a higher layer. You also have category buyers like Facebook, BackBlaze, and Netflix investing heavily into areas aimed at minimizing the economic power of cloud as a category, so they have leverage to protect their own margins.

It's possible the key "layer battle" will be between the hardware (Nvidia/TPUs) and base model (OpenAI) layers.

It's very likely hardware will win this for as long as they're the bottleneck. If value creation is a direct function of how much hardware is being utilized for how long, and the value creation is linear-ish as the amount of total hardware scales, the hardware layer just needs to let a bidding war happen, and they'll be capturing much of the economic profit for as long as that continues to be the case.

However, the hardware appears (I'm no expert though) to be something that is easier to design and manufacture, it's mostly a capacity problem at this point, so over time this likely gets commoditized (still highly profitable, but with less pricing power) to a level where the economic leverage goes to the Base model layer, and then the base layer becomes the oligopsony buyer, and the high fixed investment the hardware layer made then becomes a problem.

The 'Base+1' layer will have a large boom of startups and incumbent entrants, and much of the attention and excitement in the press will be equal parts gushing and mining schaudenfreude about that layer, but they'll be wholly dependent on their access to base models, who will slowly (and deliberately) look more and more boring apart from the occasional handwringing over their monopoly power over our economy and society.

There will be exceptions to this who are able to leverage proprietary data and who are large enough to build their own base models in-house based on that data, and those are likely to be valuable for their internal AI services preventing an 'OpenAI' from having as much leverage over them and being much better matched to their process needs, but they will not be as generalized as the models coming from the arms race of companies who see that as their primary competitive advantage. Facebook and Twitter are two obvious ones in this category, and they will primarily consume their own models, rather than expose them as model-as-a-service directly.

The biggest question to me is whether there's a feedback loop here which leads to one clear winning base layer company (probably the world's most well-funded startup to date due to the inherent upfront costs and potential long-term income), or if multiple large, incumbent tech companies see this as an existential enough question that they more or less keep pace with each other, and we have a long-term stable oligopoly of mostly interchangeable base layers, like we do in cloud at the moment.

Things get more complex when you look to other large investment efforts such as in China, but this feels like a plausible scenario for the SV-focused upcoming AI wars.
