Deploy a local AI model: requirements, hardware and controls
Running a model on your own hardware can reduce some transfers and increase control. It also shifts responsibility to the endpoint, server, logs, licences, backups and maintenance.
The short answer
Start with a precise use case and a small test set. Choose the smallest model that reaches the required quality, measure memory, speed and power on real hardware, check the licence, isolate the service and document updates, backups and shutdown.
- Size for the requirement
- Secure the full environment
- Measure before deployment
Build a controlled local deployment
1. Define the use case
Separate chat, summarisation, extraction, code, vision and document processing. Set languages, context length, acceptable latency and minimum quality.
2. Check the model
Review provenance, code and weight licences, prohibited uses, documentation and supported formats. A downloadable model is not automatically licensed for every project.
3. Size the hardware
Test system memory, graphics memory, storage, throughput and concurrency on the target machine. Quantisation reduces requirements but can change quality and speed.
4. Isolate the service
Restrict network listeners, accounts, accessible folders and extensions. Protect the interface, filter logs and control imported models and files.
5. Evaluate results
Use production-like cases and measure accuracy, latency, stability, power and correction effort. Include long data, hostile inputs and no-answer conditions.
6. Operate over time
Pin versions, review updates before deployment, monitor capacity and errors, test restoration and keep a rollback procedure.
Put the method to work
Practical case
Run two models on the same computer with ten representative questions, including one about a document you cannot upload online.
Evidence to keep
Record memory, latency, quality, resource use and outbound connections from the interface.
Make the decision
Keep the setup only if the control gained justifies maintenance and quality is sufficient for the task.
Four budgets to plan
Quality
Does the model reach the threshold for your languages and documents?
Capacity
Are memory, speed and concurrency acceptable?
Operations
Who updates, monitors, backs up and responds to failures?
Compliance
Do licences, data, access and logs meet the applicable framework?

Active services are distributed across guide-related categories, then ordered by editorial highlighting and internal score. This does not assess security, compliance or performance on your use case. Methodology.
Explore tools for this task
- Cursor — Work in an existing project on a bounded task: explain a function, fix a reproducible behaviour or prepare a reviewable change.
- Ollama — Test a model on your computer or provide a backend for a local application. Check hardware compatibility and model licensing first.
- GitHub Copilot — Explain code, prepare a bounded change or complete a useful test. Supply the expected behavior and a reproducible example before requesting a fix.
- Aider — Change a bounded function in an existing project. Identify relevant files and expected outcomes rather than sending the entire repository by default.
- LM Studio — Test a local model using authorized text and assess its quality on your hardware. Separate response speed, memory consumption and correctness.
- Open WebUI — Provide a common interface for authorized models. Define users, available connections and documents each group may access.

Frequently asked questions
Is a graphics card mandatory?
Not for every model or task, but compatible graphics hardware can greatly improve speed. Test the actual machine with the intended size and quantisation.
Does local AI guarantee confidentiality?
Only when the flow is genuinely local and the endpoint, network, logs, backups and access are controlled. Extensions and downloads can reintroduce transfers.
How should model size be selected?
Start with the smallest model that meets the quality threshold. Compare sizes on the same test set and include hardware and human costs.
