Illustrative flow · no real data · no speed comparison
The local setup shown here is fully local. The model, document processing, and search run inside the company network, with external AI calls disabled. Cloud fallbacks, web search, and other connected services need their own data-flow checks. The diagrams show processing locations, without specifying countries or network connection types.
What changes in practice
The same task. Different responsibilities.
The processing location changes the data path, who runs the system, and what you need to budget for.
What information is sent?
Cloud AI
The question and content the application includes, such as report text or chat history, go to the selected cloud service.
Local AI
The same information travels to your own server. In the setup shown above, processing and responses remain inside your network.
Who runs the AI?
Cloud AI
The provider operates the hosted model and infrastructure. Your company still manages its application, accounts, and data settings.
Local AI
Your company or chosen IT partner operates the server and model, including access permissions, updates, monitoring, and backups.
What are the costs?
Cloud AI
Service or usage fees, integration, and support. Available capacity and service terms depend on the provider.
Local AI
Hardware, electricity, maintenance, and support. Model size and simultaneous users determine the capacity you need.
A few useful distinctions
Understand the boundary.
Does the model name tell us where our data goes?
The hosting service determines the destination. For example, Azure OpenAI runs in Microsoft’s environment. A model that can also be installed locally still uses a cloud route when you call its hosted API. Choose the actual service and configuration before deciding where the processing happens.
Processing, storage, and model training are different uses. Policies depend on the product, contract, and settings. For example, OpenAI states that API data is not used for model training by default unless you opt in. Retention rules are a separate consideration.
Yes, when the model, document processing, search, and required data are available locally and external services are disabled. Setup and updates need a planned way to transfer files. Permissions, backups, and checks on AI answers are still part of operating the system.
Do we need a server room?
A small pilot may fit on a suitable workstation or a single server. Larger models and more simultaneous users need more memory and compute. We size the system around your workload and test it before recommending a purchase.
From idea to everyday use
A small pilot. A clear decision.
We start with one useful workflow and measure it with your team before expanding.
01
Choose one task
Agree on the users, the problem, and what a useful result looks like.
02
Connect approved data
Select current documents, define access, and choose suitable hardware.
03
Test a pilot
Measure answer quality, time saved, response speed, and permission checks.
04
Plan ongoing operation
Assign ownership for updates, monitoring, backups, support, and training.
Your first use case
Where does your team lose time?
Tell us about one recurring task and where the relevant information lives. We’ll help define a pilot with a clear scope and a realistic basis for deciding what comes next.
