Large Language Models (LLM)

An LLM in production isn't an API key: it's an argued model choice, a quality architecture, inference cost control and guaranteed confidentiality. LaMeDuSe AI runs LLMs in European production.

The problem you're facing

Hacked-together LLM projects collapse in production: unreliable answers, exploding inference costs, confidentiality discovered too late, and a model provider deprecating your version without warning.

Our answer

We architect your LLM usage with production rigour: per-use-case model selection, grounding in your data (RAG), continuous evaluation on business test sets, cost optimisation and a model-version migration strategy.

What LaMeDuSe AI takes care of

  • Model selection: generalist, specialised or open source
  • RAG architecture for answers grounded in your data
  • Continuous evaluation: test sets, quality metrics
  • Inference cost optimisation (caching, routing, small models)
  • Confidentiality strategy: hosted APIs or self-hosting
  • Version management and model migrations
  • Usage monitoring and logging

Our methodology

  1. 1

    Right model for the job

    The right model for each use: generalist, specialised or self-hosted open source, arbitrated on cost and confidentiality.

  2. 2

    Quality architecture

    RAG, agents and guardrails designed to limit hallucinations and guarantee answer traceability.

  3. 3

    Continuous evaluation

    Business test sets, quality metrics and drift monitoring : AI without measurement degrades.

  4. 4

    European operations

    Models run on our European infrastructure, with monitoring and inference cost control.

Technologies

OpenAI, Anthropic, Mistral, open-source modelsLangChain, LangGraphVector databases (pgvector, Qdrant)Whisper & speech-to-textComputer vision

Security & compliance

Self-hosted model option for sensitive data, environment segmentation, managed secrets and call logging.

Hosting

Self-hosting on our European cloud (France, Germany, Switzerland) or hosted APIs with data minimisation.

Maintenance

Model watch (new versions, deprecations), quality re-evaluation, inference cost optimisation.

Why LaMeDuSe AI

We run LLMs on our European infrastructure for our own products: the trade-offs we recommend, cost, quality, confidentiality, are the ones we live daily.

Frequently asked questions

It depends on three criteria: required quality, data confidentiality and budget. A generalist model fits most uses; sensitive data points toward open-source self-hosting. We arbitrate in a POC with your real cases.

Rarely as a first resort: RAG (grounding in your documents) solves most needs at lower cost and stays easy to update. Fine-tuning is justified for very specific formats or vocabulary, once RAG has been exhausted.

Four levers: caching frequent answers, routing to smaller models for simple tasks, limiting the context sent, and cost tracking per use case. Costs are managed : not suffered.

Yes, two ways: self-hosting open-source models on our European infrastructure, or using European APIs with data minimisation. The choice depends on your confidentiality requirements and needed quality.
