Chatbot

Use this component to integrate an AI-powered chatbot into your scene using the OpenAI Chat Completion API.

What it does

This component enables:

• Text input & response using LLM

• Voice input using Speech-to-Text

• Voice output using Text-to-Speech

• Image generation if the user requests it

• Tool/function calling if AI requests an action

---

1. Setting up the Chatbot

Step 1: Add the Chatbot component to any GameObject.

Step 2: Choose or create a Chat Session:

• Stores the message history and config

• Set it using Selected Session

Step 3: Select a model:

• OpenAI GPT-4o is default

• Optional: choose a separate model for summarization

2. Optional Features (Modules)

You can plug in optional features to extend the chatbot:

Feature	Component	What it does
Voice input	SpeechToText	User can speak instead of typing
Voice output	TextToSpeech	AI responses are played as audio
Image responses	ImageGenerator	User prompts like “draw a cat” return images
Tool execution	FunctionManager	AI can trigger Unity methods

If you leave these blank, the chatbot still works with text input/output only.

5. Advanced Options (Optional)

You can manually override things like temperature, max tokens, top-p, etc. These are useful if you want finer control over the LLM behavior.
