Choosing a strong AI model is not enough to build a durable AI strategy. Power, chips, cloud capacity, data systems, developer tools, workflow access and distribution all affect what an organization can deploy—and at what cost and risk. Models still matter; the strategic shift is that model choice alone no longer captures where advantage or dependency lies.
In “The Model War is Over. The Infrastructure War Has Begun,” published by Built In on September 10, 2026, Liat Ben-Zur, reviewed by Seth Wilson, reframes the familiar questions—Which model leads this week? Which codes better or has the larger context window?—as a question about dependency: where does an organization need control, and which bottlenecks could shape its economics? The headline is a strategic framing, not evidence that model development or competition has ended.

Why model rankings are an incomplete AI strategy
Model capability is only one layer in a working AI system. A model must be served on available compute, connected to permitted and useful data, integrated into a process, evaluated, monitored and secured. Someone also has to make the result accessible to employees or customers. A model can perform well in isolation while the system around it is too costly, brittle, difficult to audit or poorly matched to the workflow.

That makes a leaderboard a poor substitute for an architecture decision. The relevant comparison is not just which model is strongest today, but how a particular workload performs within the organization’s full operating environment—and what happens if a provider, price, capability or policy changes.

Where the bottlenecks sit in the AI stack
The strategic stack extends both below and above the model. A useful map follows the path from physical capacity to the user:
| Layer | What it includes | Why it can matter |
|---|---|---|
| Physical capacity | Electricity, grid access, cooling, facilities, chips, memory, networking and storage | Limits on capacity or access can affect deployment timing, scale and operating economics. |
| Cloud and compute | Infrastructure used to train, host or run AI workloads | Dependence on one provider or scarce capacity can constrain choices and create concentration risk. |
| Data and retrieval | Data quality, permissions, storage, retrieval and connections to business systems | A capable model cannot compensate for inaccessible, unsuitable or improperly permissioned information. |
| Production operations | Orchestration, evaluation, observability, security and governance | These controls determine whether a system is reliable, visible when it fails and appropriate for its use. |
| Models and developer tools | Models, APIs, coding environments and agent frameworks | They shape capability and usability, but can also become dependencies if switching is difficult. |
| Workflow and distribution | Applications, business processes, customer relationships, devices and operating systems | Control of the workflow or route to users can determine whether AI reaches them and becomes useful. |
These layers interact. A system may depend on a cloud provider for compute, a data platform for retrieval and a separate framework for agent execution. The more tightly those pieces are coupled, the harder it may be to substitute one component or diagnose an outage. A dependency map should therefore record not only what is in the stack, but what relies on what.
Why energy and facilities belong in AI planning
Electricity demand is one measurable sign that AI strategy has a physical dimension. The figures below cover data centers, not just AI workloads, and describe different geographies, periods and scenarios; they should not be treated as interchangeable predictions.

| International Energy Agency (IEA), 2025 | 415 TWh in 2024; around 945 TWh by 2030 | The IEA estimated 2024 global data-center electricity use at 415 terawatt-hours, about 1.5% of global electricity consumption. Around 945 TWh is its global base-case projection for 2030, not a measured outcome. |
| IEA, 2026 | 17% increase in 2025 | The IEA reported year-over-year growth in data-center electricity demand. This is a reported change, not a forecast. |
| IEA, 2026 | More than $400 billion in 2025; a further 75% increase expected in 2026 | The IEA said capital expenditure by five large technology companies exceeded $400 billion in 2025 and reported that a further 75% increase was expected in 2026. The latter is an expectation, not a confirmed result. |
| U.S. Department of Energy (DOE), 2025 | 11.8% by 2030; sensitivity range of 9.5%–15.3% | The DOE’s reference case estimates data centers could consume 11.8% of total U.S. electricity in 2030. Its sensitivity range is also U.S.-specific; the report gives a compounded uncertainty range of 521–843 TWh. |
Forecasts depend on assumptions about adoption, efficiency and energy-system bottlenecks. The IEA’s projections are scenarios, not guarantees that every organization will face a power constraint. They do, however, make capacity, location and energy planning relevant questions when an organization expects to scale data-center-dependent workloads.
How to find the dependencies that matter to your organization
Start with real workflows rather than an abstract inventory of AI products. For each use case, document the system’s purpose, its components, the information it uses and the consequence of interruption or error. Then answer these questions:
- Where are frontier models being used, and why? Identify the capabilities a workflow actually needs, rather than assuming the newest or largest model is necessary everywhere.
- What does each workflow depend on? Trace reliance on a model, cloud provider, data platform, retrieval service or agent framework. Note shared dependencies across use cases.
- Where is the organization’s distinct advantage? Look for proprietary data, workflow knowledge, customer trust, regulatory expertise, domain logic or distribution that competitors cannot readily reproduce.
- Which components need portability, auditability or a fallback? Consider whether a substitute can be used, what would have to change, and whether the organization can inspect decisions or reconstruct what happened.
- Where could failure happen silently? Identify failures that might produce plausible but wrong outputs, lose context, use stale or unauthorized data, or pass unnoticed through a process.
Rank dependencies by the impact of failure, difficulty of switching, concentration across workflows and ability to detect problems. This is a practical prioritization exercise, not a claim that one architecture or vendor is universally best.

Ben-Zur’s principle is to buy commodity layers, configure control layers and build where workflow creates durable advantage. Applied carefully, that means avoiding custom engineering where a standard component meets the need, while retaining meaningful control over the parts that encode an organization’s knowledge or create its customer value.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minute- Buy commodity layers: Use established capabilities for broadly available infrastructure or tools when they meet requirements and do not create unacceptable dependence. Evaluate the cost and effort of changing providers, not just the initial setup.
- Configure control layers: Set up permissions, retrieval, routing, evaluation, monitoring and governance to fit the organization’s data, risk tolerance and operating procedures. Configuration can be strategically important even when the underlying software is not proprietary.
- Build where workflow creates durable advantage: Invest in internal capability when distinctive domain logic, process integration or customer experience is central to the value. The goal is not to build every layer in-house; it is to avoid surrendering the parts that make the workflow distinct.
For example, a team might rent general-purpose compute, configure retrieval around approved internal information and build the process logic that reflects its particular service workflow. That is an illustrative way to apply the principle, not a measured case study or a recommendation for a specific supplier.
Use different decision criteria in different sectors
The same stack can produce different priorities depending on the work being done. The examples below are architectural considerations, not a scored comparison or ranking of sectors.
| Sector example | Priorities to examine |
|---|---|
| Healthcare | Data control, evaluation and audit trails |
| Software firms | Developer workflows and agent reliability |
| Financial services | Compliance, explainability and routing transparency |
Across sectors, compare options using workload fit, concentration of dependencies, portability, data permissions, auditability, visibility into failures and total economics. A strong result on one dimension does not settle the decision: a system that fits the workload may still be difficult to audit or expensive to replace.
What the infrastructure framing does—and does not—show
Infrastructure can shape how quickly and economically AI systems are deployed, but the available figures do not establish that every AI project will face the same capacity limits. Energy forecasts are uncertain, and data-center totals should not be mistaken for AI-only consumption. Likewise, evidence about infrastructure needs does not prove that model quality is unimportant.
Integrated systems are one response to the interdependence of compute, networking, storage, power and facilities. NVIDIA’s March 2026 Vera Rubin release is an example of a vendor presenting an integrated AI-factory platform across those categories. It illustrates a supplier’s approach; it is not an independent performance comparison or proof that an integrated platform is right for every organization.
The practical shift is from asking only, “Which model should we use?” to also asking, “What must this workflow depend on, what should we control, and how will we respond when a dependency changes or fails?” Model selection remains part of the answer. The infrastructure and operating choices around it determine whether that answer can work in production.
