# Use OpenRouter

> Why use OpenRouter? If ChatGPT is not available in your country, OpenRouter will be an option, but not only, check <https://openrouter.ai/> for more information

Open Router ([openrouter.ai](https://openrouter.ai/)) is a new service that gives you access to LLM models that you normally won’t have access to (GPT-4 32K, Google PaLM, Claude, etc.)

Here is how to use Open Router models on AIChatOne.

### 1. Create an account <a href="#id-1526c93422f9404c9273d7090cd10b18" id="id-1526c93422f9404c9273d7090cd10b18"></a>

Go to [openrouter.ai](https://openrouter.ai/) and create an account. Open Router allows you to use some model for free, or you can buy more credits to use the premium models.

### 2. Create an API key <a href="#id-3f2d1c434839491aa5db0bd5b58759f3" id="id-3f2d1c434839491aa5db0bd5b58759f3"></a>

After signing up, go to <https://openrouter.ai/keys> to create an API key.Enter “Any words” to the name field. Leave the “Credit limit” empty to set the limit to unlimited.

3\. Add Credits

Go to Account > Settings, scroll down to the credit section to Add Credits so you can use the generated API keys.

### 4. Enter your API key to AIChatOne <a href="#id-82dc07ad8292418993522f30fdcfeeae" id="id-82dc07ad8292418993522f30fdcfeeae"></a>

Open AIChatOne, input the copied API key and start your first conversation with AIChatOne!
