# AI providers

Before we get started you will need to prepare which AI provider you intend to use. You can choose a single one, or mix them up. These are the options:

{% hint style="info" %}
Most online AI models require some sort of pay-as-you go credits. Ensure your account is active and has budget.
{% endhint %}

* **OpenAI**\
  Online. Requires API key, create a key [here](https://platform.openai.com/api-keys).\
  A *Tier 2+ API account is recommended, else you will run into rate limits. Upgrade to Tier 2 by adding at least $10 to your account.*
* **Groq**\
  Online. Requires API key, create a key [here](https://console.groq.com/keys).
* **Anthropic**\
  Online. Requires API key, create a key [here](https://console.anthropic.com/settings/keys).
* **OpenRouter**\
  Online. OpenRouter support is basic. Use the OpenAI provider,  and change the base url to "<https://openrouter.ai/api>". Requires API key, create a key [here](https://openrouter.ai/settings/keys).
* **Ollama**\
  On Device. Download Ollama [here](https://ollama.com/).

For most AI providers, the only required information is entering your API key, leave the other fields blank unless you have a specific reason to. OpenAI users that are part of multiple organizations, can fill in their organization id (`org-xxx`).

For OpenAI you can also select a voice as it can be used as a Text-To-Speech engine under general settings.

Ensure you make the AI provider of your choice the default, by clicking the set default button.

{% hint style="warning" %}
Though on-device AI is possible, the models are currently behind the cloud models in power and intelligence. Working with on-device models requires more effort from you, the user, to help the AI understand your intent. For beginning users, we recommend using one of the cloud models.
