Mistral Medium
Vendor: mistral-medium-3-5, as of 29 September 2026
The middle tier from the French vendor Mistral AI, positioned between the large tier and the compact models. It fits tasks that arrive in volume but demand more care than pure extraction: summaries, correspondence drafts, preliminary checks. For professional secrets two routes carry, and on both the chain is closed: via Azure and via Google Vertex AI - on both the confidentiality undertaking under section 203 of the German Criminal Code is signed. In both cases a US group sits in the chain as the platform operator, and binding to the EU has to be enforced by organisational policy.
The confidentiality agreement under section 203 of the German Criminal Code is signed. We set the route up without storage at the provider (zero retention) once the provider has committed to it - at Microsoft through the exception from abuse monitoring, which usually takes months. Until then, storage and review by the provider are not ruled out.
What it is good for
- Balanced ratio of cost, response time and quality for tasks in volume
- Sold and operated by the platform itself - the same contractual and residency position as the other models sold by Azure
- EU processing evidenced in seven EU regions
Where it stops
- For complex analysis and subsumption the large tier or a reasoning model is the better choice
- Despite the European vendor, a US group sits in the chain on this route as the platform operator
- Abuse monitoring is active by default; switching it off depends on a vendor approval that cannot be booked directly
- The platform's global endpoint gives no residency guarantee - the same models can be called there as well. Binding to the EU is therefore a configuration requirement: the global endpoint is blocked by organisational policy, otherwise the EU commitment is a settings question rather than a property.
Status through us
The same model, procured differently, is a different legal position. The status above refers to procurement through us; processing takes place in a third country.
Which route carries it, with which instrument and under which condition, we set out in full to the firm before it commissions us - section 203(4) requires that the chain can be checked, not that it is published. The full matrix, with the sources behind every route, can be requested in the German catalogue after confirming your e-mail address, and we go through it in the conversation.
