How credits work
Each reply uses credits based on the model: Canto 1, Fable 2, Oriel 4. Auto picks the lightest model that suits your message. Limits refresh on a rolling basis, so credits come back as your older messages age out of the 5-hour and weekly windows. You can see exactly where you are from the ring next to the send button.
Context window
The context window is how much of a conversation Dianoetic can consider at once. When a chat gets close to the limit, starting a new one keeps replies sharp.
Without an account
Guests get 12 credits every 5 hours and a 16K context window. Create a free account for Base limits and saved chats.
