Mistral may use your Vibe conversations and uploads for AI training unless you opt out

What happened

Mistral AI's help center states that input and output data in its products — conversations, uploaded documents, and other user-provided content — "may be included in Mistral's model training programs." For the consumer Vibe app (formerly Le Chat), users are not opted out by default: training continues until the user disables the toggle labeled "Allow your interactions to be used to train our models" (Admin panel → Manage → Vibe → Privacy), or, on mobile, deselects "Enable data sharing" under Settings → Data & Account Controls. Documents attached or uploaded within Vibe count as input data. Vibe Enterprise customers are opted out of training by default, and the Vibe and Studio/API toggles are separate — each must be configured on its own. Feedback (thumbs up/down and accompanying comments) may be used for training regardless of the other settings.

Why this matters for creators

Anything pasted or uploaded into a consumer Vibe session — drafts, scripts, lyrics, manuscripts, client files — can become model-training data unless the toggle is off. Mistral's documentation notes that the opt-out applies only going forward; it does not remove data already used.

How to opt out

• Web/desktop: Admin panel → Manage → Vibe → Privacy → disable "Allow your interactions to be used to train our models".
• iOS/Android: Settings → Data & Account Controls → deselect "Enable data sharing".
• Studio/API: separate toggle in the Admin panel under Privacy ("Anonymous improvement data").

Evidence note

The help article carries no visible publication date. Its current opt-out wording was publicly documented in early September 2026 (a 2026-09-03 research digest noted the help-center update) and re-verified against the live page on 2026-09-28.
