Own your AI infrastructure decisions before they own you.
Cloud inference is fine for getting started, but scaling an AI product demands a real hardware and hosting strategy. We help you weigh on-prem against cloud using your actual workloads, bring inference costs under control, and make infrastructure choices you understand and can defend.
Your AI bill is telling you something about your infrastructure
Most AI products start the sensible way: calls to a hosted model API, a small monthly bill and no hardware to think about. That is the right choice early on, because speed of learning matters far more than cost per request.
Things change as usage grows. Inference becomes one of the largest lines in the cloud bill, latency starts to matter to customers, enterprise buyers ask where their data is processed, and the team is switching models every few weeks. Choices made casually at a few requests a minute become expensive at thousands.
AI infrastructure consulting is about making those choices deliberately: which workloads stay on an API, which belong on dedicated cloud GPUs, and whether owning hardware on-premises or in a colocation facility makes financial and operational sense. The answer is often a mix, and it should shift as the product does. Products like Nodals.ai, a client building an AI advertising platform for media owners with per-publisher models and first-party data control, show how quickly infrastructure and data control become part of what customers are buying.
The inputs that decide an on-prem vs cloud AI strategy
Before recommending anything, we gather evidence on each of these. Most teams have measured about half of them.
Workload profile
Requests per day, peak-to-average ratio, prompt and response lengths, and how steady traffic is across the week.
Latency and availability needs
Which features are interactive, and which could run as overnight batches at a fraction of the cost.
Model requirements
Whether a smaller open-weight model matches quality for your task, measured on your own evaluation set rather than public benchmarks.
Data residency and compliance
Contractual and regulatory limits on where data is processed, and what enterprise customers will ask for next.
Realistic utilisation
Owned or reserved GPUs only pay off when they are busy. We estimate the utilisation you will actually achieve, not the best case.
Team capability
Who will patch, monitor and upgrade the serving stack. Hardware without an operator is a liability, not an asset.
Hosted API, cloud GPUs or on-prem hardware?
There is no universally cheapest option. The right answer depends on volume, how predictable your traffic is, data obligations and the team available to run it.
| Hosted model API | Cloud GPUs | On-prem or colocation | |
|---|---|---|---|
| Upfront cost | None | None, or reserved capacity commitments | Significant hardware purchase |
| Cost at high, steady volume | Highest per request | Lower with good utilisation | Often lowest over the hardware life |
| Data control | Provider's terms apply | Your cloud account and region | Full physical control |
| Model choice | Provider's models, often the most capable | Open-weight models you select | Open-weight models you select |
| Operational burden | Minimal | Moderate: scaling, drivers, monitoring | High: hardware, power, spares, upgrades |
| Best for | Early products, spiky or low volume | Growing, predictable workloads | Large steady workloads or strict data rules |
GPU pricing, hardware lead times and model capabilities move quickly. We model your decision with current figures rather than last year's rules of thumb.
How an AI infrastructure review runs
Most reviews fit a two to four week Advisory Sprint. Our engineers use AI tooling to work through billing exports, logs and configuration quickly, so the time goes into analysis and decisions rather than data wrangling.
Baseline
Week 1Current architecture, model usage, cost per request and per customer, and the growth you expect over the next 12 to 24 months.
Benchmark
Weeks 1 to 2Candidate models and hosting options tested against your real prompts for quality, latency and cost.
Model the options
Weeks 2 to 3Total cost of ownership for API, cloud GPU, on-prem and hybrid scenarios, including people, redundancy and hardware refresh cycles.
Decide and plan
Final weekA recommendation, the triggers that should prompt a revisit, and a staged migration plan. If you want, our engineers then help implement it.
The goal is not the cheapest GPU. It is infrastructure that fits the product you are becoming.
Two opposite mistakes are common. One team buys hardware far too early, based on a growth projection, and ends up with expensive machines idling while the product finds its market. Another stays on a premium API long after volume justified a change, quietly handing part of its margin to a model provider.
Both are avoidable with honest numbers and a willingness to keep options open. Designing your application so models and hosting can be swapped, with a thin routing layer and your own evaluation set, is often worth more than any single hardware decision.
If your main concern is one specific lever, such as cutting per-request inference cost or running models privately for data protection, we have dedicated services for those. This work sits above them and decides where each belongs.
Questions we often hear
Is it cheaper to run AI on-premises or in the cloud?
At low or unpredictable volume, cloud APIs and cloud GPUs are almost always cheaper once hardware, power and staff are counted. On-premises hardware can become cheaper for large, steady workloads where GPUs stay busy most of the time. The break-even point depends on utilisation, model size and your team, so it is worth modelling with your own numbers.
When should a company move off hosted AI model APIs?
Consider it when inference is a major and growing cost, when an open-weight model performs well enough on your task, or when data rules require processing in your own environment. Many teams move part of the workload first, such as high-volume simpler tasks, while keeping frontier APIs for the hardest requests.
What does an AI infrastructure consultant do?
An AI infrastructure consultant assesses how your AI workloads are hosted and paid for, benchmarks the alternatives, and recommends an architecture and migration path. A good one weighs operational burden and team skills alongside hardware prices, because the cheapest option on paper is often the hardest to run.
Do we need our own GPUs to build AI products?
Usually not at the start. Hosted APIs and on-demand cloud GPUs let you build and validate without capital outlay. Owning GPUs makes sense once workloads are large, predictable and well understood.
Can you help implement the infrastructure you recommend?
Yes. Our AI-native engineers can set up model serving, routing between providers, monitoring and cost reporting, with senior review of every change. We are equally happy to hand a clear plan to your own team or oversee a vendor doing the work.
