What this is, and why it matters

What it is

A short, guided advisor that takes a real client situation and shows which Mistral model, deployment and EY offering fit it. You leave with a recommendation and a talk track.

Who it’s for

EY Partners and pursuit leads in Financial Services, Energy and Government who are about to have an AI conversation with a senior executive.

Why it matters

Clients default to the biggest model for every task. Right-sizing cuts cost and latency, opens sovereign and on-premises options, and positions EY as the adviser who knows the difference.

How to use it

Five short steps. Change any answer and the advice updates.

“What’s the smartest model?”
Ask
“What’s the smallest model that reliably solves the task?”
If the workload genuinely requires frontier intelligence, the advisor will say so. Credibility with the client matters more than any single recommendation.

Sovereign posture: how far do you want to go?

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.
