For sensitive data,
Mistral, EU-hosted, SecNumCloud certified.
Native European hosting, SecNumCloud Enterprise-Sovereign certification: the default pick when the DPO decides.
Mistral Le Chat remains the only consumer-facing tool natively hosted in the EU, with a SecNumCloud-certified Enterprise-Sovereign option announced for Q2 2026. For missions under heavy professional secrecy — health, legal, public sector — it is the only credible answer in front of regulators.
« Sovereign by design. Aggressive pricing. Minimal latency from Paris or Lyon. »
« Clear retention policy, opt-out by default on the API. Acceptable outside personal data. »
« No prompt storage in incognito mode. To use for public monitoring. »
European regulators have not settled every grey zone of the AI Act, but the doctrine is sharpening: transfers outside the EU mean a mandatory impact assessment. For a law firm, a hospital, a local authority, the legal cost of a leak through a US tool far exceeds any subscription savings. Mistral closes the question by design.
Style, nuance and calibrated refusals: three months after launch, Opus 4.7 keeps the editorial edge.
One paid subscription to start with: ChatGPT covers everything, Mistral reassures the DPO. The rest comes later.
An answer engine, not a chatbot. Sources cited by default, clean academic mode — indispensable for monitoring.
Six questions, two minutes. Personalized verdict based on your real constraints — price, GDPR, context, code.
