Troubleshooting
I hit a limit. What now?
Free has limited messages, searches and coding sessions (Mistral pricing). Start a new chat with a short summary instead of dragging a long one.
The answer cites a page that doesn't say that.
Treat the claim as unverified. Ask: quote the exact sentence from that page that supports this, or say it isn't there. Then open the page yourself.
It forgot my earlier instructions.
Long chats push early text out of context. Put standing instructions where Mistral Le Chat (now Vibe) keeps them (Mistral's docs describe Vibe (the unified agent for productivity and coding, on web, mobile, terminal and editor), Studio (developer console and API) and Admin.) and start a fresh chat.
It agrees with everything I say.
Ask it to argue the other side and list the strongest evidence against your view, with sources.
How do I keep costs down?
Pro $14.99/mo excl. tax ($5.99 for verified students), Team $24.99 (Mistral). On the API, batch jobs are 50% off and cached input up to 90% off.
Cost control
Free has limited messages, searches and coding sessions (Mistral pricing).
- Test with the free tier on real tasks for a week first.
- Set a calendar reminder 2 days before any renewal.
- Keep one paid assistant, not three, unless each earns its place.

Privacy and safety
Turn on only the connectors a task needs and test them with a read-only request first.
- Don't paste passwords, ID numbers, card numbers or other people's private details.
- Assume the company can read and keep your chats unless its official policy says otherwise.
- For health, money or legal decisions, confirm with a professional or an official source.
Failure modes to watch
