# Configure LLM Providers and API Keys in Aether

> Add your OpenAI, Anthropic, Google, DeepSeek, Groq, Mistral, or Cloudflare API keys to Aether and start using any supported LLM model.

Aether uses your own API keys to call LLM providers directly from your device. There is no proxying, no Aether account, and no subscription — you bring your keys, and Aether connects straight to the provider's API on your behalf.

## Editing or Removing a Provider

## Switching the Active Model

After you add a provider, tap the **model selector** in the chat composer (the pill-shaped button showing the current model name) to open a full list of models available across all your configured providers. Tap any model to switch to it for the current session or set it as your global default in Settings → Model.

<Note>
  API keys are stored in Aether's private app storage on your device. They are transmitted only to the respective provider's API endpoint — never to any Aether-operated server.
</Note>

<Warning>
  If you uninstall Aether, your stored API keys will be permanently deleted along with all other app data. Back up your keys in a password manager or secure location before uninstalling.
