AI Settings

AI Settings allow you to configure the default AI provider, choose the models used across your instance, and define global system instructions for your entire Mixpost instance.

Default AI Provider

Once you've integrated one or more AI services, you need to set a default provider that will be used across your instance.

1. Navigate to Admin Console -> Settings -> AI
2. Select your preferred AI Provider from the dropdown.
3. Select the Model and, optionally, the Fast model you want to use.
4. Save the changes.

The selected provider and models are used for all AI Assistant interactions across all workspaces.

Models

Each provider exposes two model tiers so you can balance quality against cost:

• Model — the default, higher-accuracy model. It powers the AI Assistant and any task that needs nuanced output.
• Fast model — a cheaper, faster model used for low-stakes, high-volume tasks.

Leaving a field on Default uses the provider's recommended model for that tier.

Custom Model ID

Both the Model and Fast model dropdowns include a Custom model ID option. Choose it to type any model identifier the selected provider supports — useful for accessing newly released models that aren't in the list yet, or provider-specific deployments.

tip

Enter the exact model identifier expected by the provider's API (for example claude-opus-4-8 or gpt-4.1-mini). An invalid identifier will cause AI requests to fail.

Engagement (Inbox) Models

The Inbox automatically classifies incoming messages — applying labels, detecting sentiment and spam, and moderating hate speech. You can choose which models power this classification independently of the AI Assistant, so the high-volume classification workload can run on cheaper models without affecting content generation.

These models are configured once, at the instance level, by an administrator. They are not exposed in the per-workspace Inbox settings.

note

The Engagement (Inbox) section appears only when the Inbox Engagement feature is enabled for your instance. If the feature is disabled, these fields are hidden.

1. Navigate to Admin Console -> Settings -> AI
2. Under Engagement (Inbox), select:
   • Engagement model — a higher-accuracy model used for labelling and hate-speech moderation.
   • Engagement fast model — a cheaper model used for sentiment and spam detection.
3. Save the changes.

Leave either field on Same as Model / Same as Fast model to reuse the general models configured above.

Global System Instructions

Global system instructions are instance-level directives that guide the AI's behavior across all workspaces and users. These instructions are applied to every AI interaction, regardless of which workspace is being used.

Use global system instructions to:

• Set content policies or restrictions at the instance level.
• Specify formatting preferences that apply universally.
• Enforce compliance or brand guidelines across all workspaces.

How to Configure

1. Navigate to Admin Console -> Settings -> AI
2. Enter your instructions in the Global System Instructions field.
3. Save the changes.

tip

Global system instructions are different from Brand Voice. Global instructions apply at the instance level, while Brand Voice is configured per workspace to maintain each brand's unique identity.
