With the assistant you never pick an AI model, only a mode: Lite, Standard, or Premium. The mode determines quality and price, REOS AI takes care of the rest. Billing is fair, per message, based on actual cost, with bundling for small amounts.
The three modes
Switching mode in the middle of a chat
The mode sits at the top right next to the chat title and can be changed at any time, including mid-conversation. The change applies from the next answer onwards; answers already written stay as they are and are not recalculated. So you can run a piece of research in Standard and switch to Premium only for the wording that matters.
If the chat is already long, a note in the picker points out that the assistant will read the entire history again after the switch. The next answer therefore costs more once, after which it is back to the normal price of the mode. In short chats this is negligible, so the note does not appear there.
In a chat that someone shared with you, the mode is display only. Changing it is up to whoever owns the chat, because that is where the credits are charged.
Model selection
REOS AI picks the concrete AI model automatically, matching the complexity of your request. You never have to deal with model names.
Owners and admins can still steer this: under Settings > Assistant > AI models (Einstellungen > Assistent > KI-Modelle) a fixed model can be pinned per mode, separately for text and image. Bringing your own provider keys (BYOK) is already listed there but still locked in the current version ("Bald verfügbar", coming soon).
Per-message billing
Every message is billed based on the cost it actually incurred, multiplied by the mode factor (0.15x, 1x, or 3.5x). There is no flat price per message: a short question costs less than a long research task with many tool calls.
To keep your credit history readable, small amounts are collected: only once they add up to 5 credits is a single entry booked, visible as KI-Assistent · gebündelte Nutzung (N Nachrichten) (AI assistant, bundled usage, N messages). Each person only pays for their own usage, never for someone else's bundle.
Cost displays
Empty balance
When your credit balance is used up, the assistant does not start a new answer and reports: Dein Credit-Guthaben ist aufgebraucht. Bitte lade Credits nach. (your credit balance is used up, please top up credits). If your workspace uses extended usage with a budget, the message reads accordingly: Dein Credit-Guthaben und dein Budget für zusätzliche Nutzung sind aufgebraucht. Bitte lade Credits nach oder erhöhe dein Budget. How to top up is covered in the top-up guide.
Cancellation and rate limit
- Cancellation: If you stop a running answer, the part already written stays, and only the cost incurred up to that point is charged.
- Rate limit: Each person can start up to 20 chats per minute. Nobody reaches that in normal work; if you do, wait a moment and try again.
