Mistral · EU AI Act
Mistral has to mark the output. They have not said with what.
Mistral is on the Commission’s list with OpenAI, Google, Anthropic, Meta and Microsoft. The rule is in force. The explanation is not. If Le Chat or the API marks its output, the trail is in the words.

Choose the surface, then the tool
| Surface | Gifi action | What can be verified |
|---|---|---|
| Ordinary words | Rewrite the prose | The words changed; no private detector certificate |
| C2PA, EXIF, XMP, properties | Strip named metadata | Action list plus an independent reinspection |
| Pixels, audio, or video | Not supported | No removal claim |
A signature is not a method
Article 50 requires a machine-readable mark. The Code is one way to show it. Mistral signed. They have not named a carrier, a key or a detector. A rewrite still changes the words. That is the lever, not a certificate.
Le Chat can still leave a file behind
C2PA, EXIF or document properties we can strip. Soft binding can survive. Pixels, audio and video stay out of scope.
What this cannot promise
- A rewrite does not prove the text was never AI-assisted.
- No one outside the lab can certify their detector. The key is private.
- Pixel watermarks, audio and video are out of scope.
Questions this usually raises
- Does Mistral watermark text?
- They signed. They have not published how.
- Should I still rewrite it?
- If you need the words changed, yes. That is all an honest tool can do.
- Can you detect a Mistral mark?
- No. We cannot see their key. The paste box finds hidden characters, not a Mistral detector.

Statistical signal? Rewrite the prose.
A Mistral mark, if it is in the words, needs different words. Hidden characters and C2PA need the file cleaner.
