# 2. Language Model

The Language Model (LLM) is the foundation of the AI Builder. It is the "**brain**" that drives how the character or agent behaves and performs tasks. 

You can select any LLM of your choice from the 20+ available models.

### Available Language Models

There are two types of AI Models available in AI builder. 

1. **Skillful Models**

These models are advanced and **capable of using strategies, tools/skills, and memory** to perform complex tasks. 

Purpose: Ideal for niche tasks or multi-step problem-solving where the model must go beyond basic interactions, such as web scarping or fetching specific data from an API.

Example Use Case: A financial advisor bot connected to real-time stock market data and user financial records to provide personalized investment advice.

**Currently available Skillful Models (LLM) :** 

* GPT o3 Mini
* GPT-4
* GPT-4o
* GPT-4o Mini
* Gemini-2.0-flash-exp
* Gemini-2.0-flash
* Gemini-1.5-pro
* Gemini-1.5-pro-latest

2. **Basic Models**

These models are **limited to text-based interactions and lack the ability to use external tools or retain memory.**

Purpose: Best for simple conversational tasks like FAQs or chats.

**Currently available Basic Models (LLM):** 

* Claude 3 Opus

**How LLMs Work Within AI Builder?**

The LLM processes the character template, including:

* Who the character is: Defined in the persona, including backstory and personality.
* Context of character: Detailed in the scenario for context-specific actions.
* Example dialogues: Provide structure to ensure the character responds consistently.

*Note*: Basic AI models may evolve in the future to support additional functionalities such as ability to use skills.
