# Cloud

Run models in Ollama's cloud from your apps or terminal. No model or app download required.

## API Key

Create an [API key](https://ollama.com/settings/keys), then set it in Bash or Zsh:

```shell theme={"system"}
export OLLAMA_API_KEY="your_api_key"
```

Send a request from the same terminal:

```shell theme={"system"}
curl https://ollama.com/api/chat \
  -H "Authorization: Bearer $OLLAMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gemma4:31b",
    "messages": [
      {
        "role": "user",
        "content": "Say hello in one sentence."
      }
    ],
    "stream": false
  }'
```

Read the answer from `message.content`. Keep your API key out of browser code and source control.

You can also use [OpenAI](/api/openai-compatibility) or [Anthropic](/api/anthropic-compatibility) clients. Each supports a subset of the original API. No Ollama installation is required.

## Ollama App or CLI

[Download Ollama](https://ollama.com/download). Open the app, or run:

```shell theme={"system"}
ollama
```

Follow the setup prompts and sign in to use cloud models.

On macOS, open **Apps** and connect Claude or ChatGPT. For coding agents, run a launch command:

<CodeGroup>
  ```shell Claude Code theme={"system"}
  ollama launch claude
  ```

  ```shell Codex CLI theme={"system"}
  ollama launch codex
  ```

  ```shell OpenCode theme={"system"}
  ollama launch opencode
  ```
</CodeGroup>

For more integrations, open the Ollama app or run `ollama` in your terminal.

Ollama handles sign-in for connected apps. See the [quickstart](/quickstart) for setup.

## Models

Browse [cloud models](https://ollama.com/search?c=cloud), or list them with the API:

```shell theme={"system"}
curl https://ollama.com/api/tags
```

For API requests to ollama.com, use the name returned by this list, such as `gemma4:31b`. In the Ollama app or CLI, use `gemma4:cloud`. Cloud models do not need to be downloaded.

## Usage

Check your [usage](https://ollama.com/settings/usage) or compare [plans](https://ollama.com/pricing).

## Retirements

[Usage settings](https://ollama.com/settings) show upcoming retirements for models you've recently used. Switch models before the retirement date. Downloaded local models are not affected.

## Data handling

Ollama processes cloud prompts and responses to answer your requests. We do not use them to train models. Read the [Privacy Policy](https://ollama.com/privacy) for details.

To use only local models, [disable cloud features](/faq#how-do-i-disable-ollama-cloud-features).
