Switch the active provider and model

Activate a provider through model sync

• Open Settings → AI Providers and select a configured provider
• Choose Sync now
• On success, Kition enables that provider and makes it active
• If the previous selected model is missing, Kition selects the first returned model
• Review that automatic choice in the Agent model picker before starting work

Switch from the Agent

The Agent model picker lists discovered models from enabled providers. Selecting an entry saves both its provider and model, so the next Agent request and other AI surfaces that use the desktop model settings can follow the new active selection.

Changing the selection does not cancel or rewrite a request that is already running. Wait for the current turn to finish or stop it before relying on the new model.

What switching does not do

• It does not delete credentials for the previous provider
• It does not move provider billing to Kition Cloud or between external providers
• It does not guarantee that every returned model supports Agent tools, images, reasoning controls, or hosted web search
• It does not create a workspace-specific override

If a model is missing or unusable

• Run Sync now again after the provider grants model access
• Confirm the provider remains enabled and its credential has not expired
• Choose a text-generation model rather than an embedding, image, audio, or moderation model
• Check that the model supports the configured responses or anthropic_messages wire
• Disconnect and reconnect only after preserving any provider-side information you need for diagnosis
