// the provider default), the model id and the model's default system
// prompt. Trusted is set only for models an operator configured in the
// admin: their calls may reach local-network endpoints (fetchguard
// TrustedMode). Every other config, such as a user's or an organisation's
// own key, runs guarded (fetchguard PublicOnlyMode). APIKey is a secret:
