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.

Key points

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. 1. Define the use case

    Separate chat, summarisation, extraction, code, vision and document processing. Set languages, context length, acceptable latency and minimum quality.

  2. 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. 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. 4. Isolate the service

    Restrict network listeners, accounts, accessible folders and extensions. Protect the interface, filter logs and control imported models and files.

  5. 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. 6. Operate over time

    Pin versions, review updates before deployment, monitor capacity and errors, test restoration and keep a rollback procedure.

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?

Interfaces, runtimes and tools for local AI

These active services cover local runtimes, interfaces and development. Verify supported platforms, licences, formats and recommendations on the official project site.

How is this selection produced?

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.

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.
