Local and On-Premise AI
Deploy artificial intelligence on your own infrastructure: confidentiality, data control and independence from external services.
When data cannot go to the cloud
Some organisations cannot — or do not want to — entrust their data to an external AI service:
- confidentiality: medical, legal, strategic data;
- data control: knowing exactly where it is processed and stored;
- sovereignty: independence from foreign actors;
- infrastructure control: internal security or continuity requirements;
- specific environments: isolated sites, limited connections.
For these companies, the question is not "AI or no AI", but "how to benefit from AI without giving up data control".
What is local AI, simply
Local AI runs on the client's infrastructure — company servers or a chosen datacentre — rather than fully depending on an external AI service.
Concretely:
- a local LLM is a language model running on your machines;
- documents stay with you: they are never sent to a third party;
- local RAG allows this AI to answer from your internal documents, without data leaving;
- the GPU infrastructure is sized to run these models with acceptable performance.
The choice between local AI and cloud AI is not ideological: it is a question of balance between confidentiality, cost and need (see our article *Local AI vs Cloud AI: How to Choose?*).
AI deployments on your infrastructure
Technea studies and sets up:
- local LLMs: model choice, installation, configuration;
- self-hosting: AI hosted on your servers, under your control;
- local RAG: the document assistant that answers without sending your documents elsewhere;
- infrastructure sizing: which compute needs, which machines.
The Lab's work on local AI and self-hosting directly feeds these choices: which models, which performance, which limits.
Concrete examples
- Law firm or legal department: analysis of sensitive documents without data leaving.
- Industry: assistance to teams on a site with limited connections.
- Public organisation: data sovereignty requirements.
- Cautious company: starting with local AI before evaluating external services.
How local AI is decided and set up
1. Need analysis: which use cases, which data, which constraints. 2. Feasibility study: which models can answer, on which infrastructure. 3. Sizing: compute, memory and storage needs. 4. Deployment: installation and configuration on your infrastructure. 5. Evaluation: answer quality, performance, operating costs.
What it changes
- data stays with you: no departure to a third party;
- complete control: models, versions, updates, access;
- independence: no dependency on an AI service provider;
- controlled costs: no per-usage billing;
- continuity: AI works even without an external connection.
