An EY–Mistral alliance initiative
Mistral Navigator Discover where Mistral fits your client’s business challenges.

Does every AI task really need a frontier model?

And is it even allowed to run where your client’s data lives?
And can it adapt and scale as the business changes?

Discover where Mistral can deliver the right level of intelligence, economics, deployment flexibility and sovereignty for your client’s AI workload.

About 3 minutes Start with the three journeys below

What is Mistral Navigator?

Mistral Navigator is an EY–Mistral guided advisor that helps you understand Mistral’s capabilities and connect them to client challenges & priorities, transformation opportunities and relevant EY propositions that you can take to market.

01 Explore the capability

Why the enterprise AI conversation has moved from capability to cost, control and adaptability; what each model in the Mistral line-up is designed for; and why the smallest model that reliably performs the task is usually the right recommendation. The Navigator is equally clear about where a frontier model is the better answer.

Why Mistral?
02 Map to client scenarios

Start with the journey that matters: Solve a business challenge, Build an AI capability, Control AI deployment, or Run intelligence at scale through a managed service. Navigate from there through relevant client scenarios, sector priorities and use cases.

Choose your journey
03 Chart your journey

Understand the EY service offerings and who to engage next to shape the detailed client proposition — from EY–Mistral alliance leaders to solution specialists. Move from the initial conversation to a qualified opportunity and an actionable pursuit.

The deployment spectrum

Where a Mistral model can actually run — and why it decides which client conversations are even possible. Most providers cover the left of this line. Open weights cover all of it.

Why Mistral?
The burning question Three of them, actually.

Can your client control where their AI actually runs?

Can one line-up cover every task across the enterprise?
And can it be tuned on their own data, inside their own perimeter?

Answer all three and Mistral belongs in the conversation. Answer none and a frontier model is the better recommendation — this page will say so.

A 3–5 minute executive read The short answer, then three sections

The short answer

Three guarantees that arrive as one line-up, not three separate procurements.

01Why this conversation, now

Three shifts that changed what clients are actually asking for — and what they are no longer impressed by.

Where Mistral sits Mistral is not a replacement for a frontier lab.

It is the right answer when the work has to run somewhere specific, when cost per task decides whether the use case is viable, or when the client needs a model they can retain, inspect and tune on their own data. Where none of that applies, a frontier model is the better recommendation — and the client journey in this Navigator will say so.

    Your AI. Your data. Your control.

    Open weights, deployable inside your perimeter, and fine-tuned on your own data on your own infrastructure — with EY to take it from a conversation to production.

    Mistral case studies

    What Mistral has publicly deployed, by sector.

    Announced deployments only, drawn from the client’s or Mistral’s own statements. Each entry carries its source, and an outcome figure appears only where one was published. Nothing here is modelled, extrapolated or estimated.

    Public references, gathered from company announcements. Confirm currency and detail with the alliance team before using any of this with a client.

    Sovereign AI
    The sovereignty question Three of them, actually.

    Where does your client’s AI actually run?

    If the vendor walked away, would it still run at all?
    And what could they prove to a regulator on Monday?

    Sovereignty is a deliberate design choice across every layer of the AI stack — not a hosting decision. Set the posture first, then see where it has to be designed in.

    A 4-minute read Posture, then the framework, then the law

    01Sovereign posture: how far do you want to go?

    Start with the decision, not the diagram. Sovereignty is a dial, not a switch — turn it to see what each posture means at the Infrastructure, Models, Data and Application layers, and how EY and Mistral help.

    Most organisations sit at different postures for different layers. That combination is the architecture conversation.

    02Five layers, five pillars

    Where the posture you just set has to be designed in. Each layer carries its own sovereignty decision, and the five pillars frame all of them.
