New: Run AI anywhere your cloud runs
Learn more
AI is one of the fastest-growing line items in cloud budgets. It's also the one with the least visibility.
Ask any FinOps team for a breakdown of AI infrastructure costs by product line, and you’ll often get an answer like this:
“Around 70% accurate.”
Not because the data isn’t there, but because it’s everywhere.
GPU workloads run across multiple clouds. Each provider has its own billing logic, instance taxonomy, and cost dashboard. There’s no unified view.
So when the real question comes — what should we scale, optimize, or cut — there’s no clear answer.
About 85% of organizations misestimate AI costs by more than 10%, and nearly a quarter are off by 50% or more (Benchmarkit & Mavvrik, 2025 State of AI Cost Management). Less a budgeting failure, more a visibility problem.
Most cloud cost management solutions assume three things:
GPU workloads break all three.
1. Supply is constrained and volatile
You’re not just optimizing usage, you’re competing for availability.
Teams often take whatever GPU they can get, wherever they can get it. That kills the assumptions behind rightsizing, reservations, and one provider boundary.
2. Each provider bills differently
AWS bills GPU instances as EC2 with an instance-type prefix. Azure bills them under Virtual Machines with NC or ND series naming. GCP uses a separate Compute Engine billing line with accelerator surcharges. Nebius and AI-optimized providers have entirely different models. There is no common format.
3. Workloads are bursty and experimental
AI workloads don’t run like steady-state apps. They spike, idle, and scale unpredictably. That makes traditional forecasting and commitment strategies far less effective.
4. Utilization is invisible to cost tools
A g5.xlarge running at 8% GPU utilization costs the same as one running at 95%. Standard cost dashboards show you the spend — they don't show you whether that spend is doing anything useful. Without utilization data alongside cost data, there's no signal for rightsizing.
5. Egress costs are hidden until they arrive When AI workloads move data between clouds — training data to GPU, model artifacts to serving endpoints — egress charges accumulate in a separate billing category. Cloud data transfer fees total an estimated $70–80 billion annually across the industry. (McKinsey, Feb 2026) However, most don't see it coming.
Back to the FinOps team: That “~70% accurate” answer maps directly to the above blind spots. Most likely, GPU infrastructure gets split across providers with no centralized visibility. Cross-cloud data movement shows up as egress in a completely different billing category than the compute it supports. It's just the default state for any multi-cloud AI environment without cross-provider cost attribution built into the operating model.
GPU compute has gone from a specialist workload to the default infrastructure for any AI initiative. Most companies are provisioning GPU compute across multiple providers, because GPU availability varies by region and provider, and locking into one hyperscaler's AI services limits the available GPU pool and deepens vendor dependency that most organizations are actively trying to reduce.
The instinct to diversify providers for GPU access is commercially rational, but it compounds the cost visibility problem with every provider added.
Which product team's AI project is generating the most GPU spend? Which inference environment is running at 6% utilization and should be shut down? Which cluster should be consolidated, and which should be scaled? These are straightforward operational questions. They become impossible to answer when the data to answer them is split across three provider dashboards in three different formats.
"You can't optimize GPU costs you can't see. See GPU spend across every provider, in one view: https://www.emma.ms/ai/gpu-infrastructure-across-5-clouds
The inverse is equally true. When a high-performing AI workload shows real business impact, the case for scaling it should be demonstrable in cost terms. What's the GPU spend? What's the cost efficiency compared to a comparable workload on a different provider? Without cross-provider attribution, the CFO who wants to invest in AI can't make the investment case with precision, and the one who wants to cut AI spend can't identify where the waste actually is.
Dashboards that aggregate billing data across providers are available. However, the problem is that they normalize cost without normalizing utilization, and they don't have the attribution granularity that GPU workloads require.
What unified visibility for AI infrastructure requires is cost attribution at two levels simultaneously:
Some platforms are beginning to push toward workload-level attribution — mapping costs to workloads, teams, and business functions — but this remains an emerging capability rather than a standard.
Without connecting these layers, the data exists, but the insights don’t.
It also requires egress costs to be visible in the same view as compute costs, not in a separate billing report from a different provider. The inference endpoint running on Google Cloud Platform doesn’t look expensive in isolation — compute costs stay low. But if it’s pulling model artifacts from Microsoft Azure, the real cost shows up as cross-cloud data egress on the Azure side.
Depending on how often artifacts are fetched — at startup, during scaling events, or continuously — that cost can shift from negligible to a persistent drain.
Either way, the problem is the same: the cost is real, but it’s invisible where the workload actually runs.
Unified cost attribution is a prerequisite for GPU cost optimization, but it isn't optimization itself. Seeing that a cluster is running at low utilization doesn't automatically right-size it; that still requires engineering action. Seeing that Provider A is 20% cheaper than Provider B for the same GPU configuration also doesn't automatically migrate the workload. It requires operational capability to provision and connect workloads across providers.
The full value of GPU cost visibility is realized when it's part of an operating model that can act on what it sees, and not just report it. Visibility without the ability to move workloads, adjust configurations, and govern what gets provisioned turns data into noise. The FinOps and engineering functions have to close the loop together.
GPU compute is the fastest-growing, highest-unit-cost category in cloud budgets, and it's the one category where the standard FinOps toolchain was built for a different era. The fragmentation is structural — multiple providers, multiple billing formats, no unified attribution — and it compounds with every new AI initiative that comes online.
The CFO who can answer "which AI workloads are worth scaling and which should we cut?" with precision has a structural advantage over one who can only answer it to 70%. However, this won’t just be a FinOps tool upgrade. It'll have to be an infrastructure operating model change. And it'll be the one that makes every other AI investment decision actually answerable.
