0. Overview

The LLM API Connector is a framework that enables unified access to various AI models (Claude, GPT, Gemini) within a Unity environment. This framework provides a consistent interface for utilizing APIs from different AI providers, offering features such as message exchange, streaming, and tool calling capabilities.

1. Basic Setup

1) Adding the Component to a GameObject

To use AIClient in a Unity scene, you need to add it as a component to a GameObject:

  1. Create an empty GameObject

  2. Click Add Component in the Inspector and search for "AIClient"

2) Setting API Keys

You must set API keys for each AI provider:

  1. You can set this directly in the Inspector: Add model category and API key pairs in the Model Category Key Pairs section

  2. You can also set model category and API key pairs in code

    // Get a reference to AIClient in your script
AIClient aiClient = FindFirstObjectByType<AIClient>();

// Set API keys
aiClient.AddModelSetting(AIModelCategory.Anthropic, "your_claude_api_key");
aiClient.AddModelSetting(AIModelCategory.OpenAI, "your_openai_api_key");
aiClient.AddModelSetting(AIModelCategory.Gemini, "your_gemini_api_key");
