In Models you set two roles:
Each role can have backups. Click Add fallback; if the main choice fails, Cadence tries the next one. Reorder with Move up and Move down.
Pick a model for one bot
Open the bot’s settings, then Advanced, then Model. Space default follows the space setting. Under Thinking, choose how hard the model thinks before answering, from off up to max, when the model supports it. A routine can also use its own model.Disconnect
Disconnecting a provider removes that connection from every space you use it in.On a self-hosted server, the operator can also provide server-wide keys. See Configuration.
