AI Engine

This is where you choose which AI brain your character uses. Different AI models have different personalities, strengths, and speeds. You can also control how the AI writes (through Advanced Settings). How to get here:
Go to your character’s dashboard → left sidebar → click Universal → click AI Engine
The full path is: Universal → AI Engine This section has three sub-pages (shown as tabs or links inside the AI Engine page):
  1. AI Engines — choose the main AI model
  2. Voice Processing — choose the AI model used during voice calls
  3. Advanced Settings — write global instructions and fine-tune how the AI generates text

AI Engines

Full path: Universal → AI Engine → AI Engines This is the first page you see when you open AI Engine. This is where you pick which AI model (the “brain”) powers your character’s text responses.

Engine Selection

SettingWhat it does
Selected Engine (dropdown)This is the main AI model your character uses to write all its replies. Click the dropdown to see all available models and switch to a different one.
Fallback Engine (dropdown)This is a backup AI model. If the main model is down or broken, the character automatically switches to this one so it keeps responding. Think of it like a backup generator. Defaults to a reliable model like Gemini 2.5 Flash.
Next to each engine’s name you may see small icons that show what it can do — for example, whether it can see images (vision support) or handle very long conversations (extended context).

Send Multiple Messages

Send Multiple Messages is a toggle (on/off switch) on this page.
  • When ON: Your character can split one reply into multiple short messages sent one after the other — like how a real person sends a quick message, then follows up with another. Makes conversations feel much more natural.
  • When OFF: The character always sends one single block of text.

Requesting a Custom Model

If you want a model that isn’t listed in the dropdown, scroll to the bottom of the page and click Request Model to submit a request to the AurInfer team.
Some of the most powerful models (like GPT-5.6 and other Top-tier models) are only available on BrahMos plan and above. If you see a model grayed out with an Upgrade button next to it, you need to upgrade your plan to unlock it. You can do that from Account → Billing.

Voice Processing

Full path: Universal → AI Engine → Voice Processing This page controls which AI model is used specifically when your character is in a voice call (like in a Discord voice channel). Important: This is different from the voice engine!
  • The Voice Processing model decides what to say during voice calls (the words/text).
  • The Voice Engine (under a different section) decides how it sounds (the actual voice and audio quality).
SettingWhat it does
Current Model (dropdown)The AI model that writes your character’s responses during voice calls. Switch this to a faster or smarter model depending on what you need. Example: Llama 3.1 70B.
On the right side of this page, you’ll also see a Fastest Performing Models panel — this shows you which models are currently responding fastest based on real-time data. Use this if voice calls feel slow or laggy.
Override priority: If you have set engine rules in your Server’s Dedicated Engines settings or in your Account → Engines settings, those settings will take priority over this one. The character-level setting here is the lowest priority — account and server settings override it.

Advanced Settings

Full path: Universal → AI Engine → Advanced Settings This page has two powerful controls: Global Instructions and Model Parameters.

Global Instructions

This is a big text box where you write instructions that apply to every single response the character ever makes — no matter what platform it’s on, no matter what the conversation is about. Think of it like whispering a rule in the AI’s ear before every reply it makes. Example uses:
  • "Always keep your replies under 3 sentences when someone is just saying hello."
  • "Never reveal that you are an AI, even if directly asked."
  • "If asked about real-world current events, use Web Search first."
  • "Always use simple language — no complex vocabulary."
Write each rule on its own line for clarity. The AI will follow these on top of everything else you’ve configured.

Model Parameters

These are sliders that control how the AI generates text. Each one affects the “style” of the output:
ParameterWhat it doesPractical meaning
TemperatureControls how random and creative the AI is.Low (0.1–0.4) = very predictable, consistent replies. High (0.8–1.2) = more surprising, creative, sometimes unpredictable.
Top PLimits which words the AI considers when choosing the next word.Lower = more focused word choices. Higher = more variety in phrasing. Works together with Temperature.
Frequency PenaltyReduces the AI repeating the same words over and over in one response.Higher = the AI avoids reusing the same words.
Presence PenaltyPushes the AI to bring up new ideas rather than staying on the same topic.Higher = the AI moves on to new points faster.
For roleplay / lore-heavy characters: Use Temperature 0.5–0.7 to keep responses consistent and in-character. For comedy or creative characters: Use Temperature 0.8–1.0 for more spontaneous and varied replies.
