Chai Integration

Chai is a platform for building and interacting with AI chatbots. It provides tools for developers to create engaging conversational characters and deploy them to a large user base, with support for custom model backends.

Chai's developer platform supports custom API endpoints, allowing you to connect LLM API as the model backend for your chatbots.

Prerequisites

An LLM API account with an API key
Chai installed or accessible

Setup

Get Your LLM API Key

Log in to your LLM API dashboard
Click Create Key to Start
Copy your new API key immediately — it will only be shown once
Store the key securely (e.g., in a password manager or .env file)

LLM API is an OpenAI-compatible gateway that gives you access to dozens of AI models through a single API key and endpoint.

Configure LLM API in Chai

Sign up for a Chai developer account at chai-research.com.
Navigate to your bot's Model Configuration settings.
Select "Custom" or "OpenAI Compatible" as the model backend.
Enter the following details:
- API Key: paste the key you copied from app.llmapi.ai/api-keys
- Base URL: https://api.llmapi.ai/v1
- Model: the model ID you wish to use
Click "Save" to apply.
Test your bot --- responses will now be generated via LLM API.

Test the Integration

Verify that Chai can successfully communicate with LLM API by sending a test request. All requests will now be routed through LLM API.

Using LLM API gives you access to a wide range of models to find the best fit for your chatbot's personality and use case.

Benefits of Using LLM API with Chai

Multi-Provider Access: Use models from OpenAI, Anthropic, Google, and more through a single API
Cost Control: Track and limit your AI spending with detailed usage analytics
Unified Billing: One account for all providers instead of managing multiple API keys
Caching: Reduce costs with response caching for repeated requests
