### Run a model

```
ollama run gemma4
```

### Launch integrations

```
ollama launch
```

Configure and launch external applications to use Ollama models. This provides an interactive way to set up and start integrations with supported apps.

#### Supported integrations

- **OpenCode** - Open-source coding assistant
- **Claude Code** - Anthropic's agentic coding tool
- **Codex** - OpenAI's coding assistant
- **VS Code** - Microsoft's IDE with built-in AI chat
- **Droid** - Factory's AI coding agent

#### Examples

Launch an integration interactively:

```
ollama launch
```

Launch a specific integration:

```
ollama launch claude
```

Launch with a specific model:

```
ollama launch claude --model qwen3.5
```

Configure without launching:

```
ollama launch droid --config
```

#### Multiline input

For multiline input, you can wrap text with `"""`:

```
>>> """Hello,
... world!
... """
I'm a basic program that prints the famous "Hello, world!" message to the console.
```

#### Multimodal models

```
ollama run gemma4 "What's in this image? /Users/jmorgan/Desktop/smile.png"
```

### Generate embeddings

```
ollama run embeddinggemma "Hello world"
```

Output is a JSON array:

```
echo "Hello world" | ollama run nomic-embed-text
```

### Ask a decision model

```
ollama run nimble --ask "Is a refund being requested?" < ticket.txt

ollama run nimble --ask "Which team should handle this?" \
  --choice billing="Payments and refunds" \
  --choice technical="Software problems" < ticket.txt

ollama run nimble --ask "How urgent is this?" \
  --level "Routine" \
  --level "Soon" \
  --level "Immediate" < ticket.txt
```

The state is piped in or given after the model name, as text or JSON. Each `--ask` question is answered yes or no, unless it's followed by labels to choose from (`--choice`) or levels to score it on (`--level`). See [Decision](/capabilities/decision#ask-from-the-terminal).

### Speak with a speech model

```
ollama run phonon "Hello from Ollama."

ollama run phonon --voice Zoey "Hi, this is Zoey."

ollama run phonon "Save this to a file." > speech.wav
```

The audio plays through your speakers, or is written as a WAV file when the output is redirected. Run it without text to speak each line you type. See [Speech](/capabilities/speech#speak-from-the-terminal).

### Download a model

```
ollama pull gemma4
```

### Remove a model

```
ollama rm gemma4
```

### List models

```
ollama ls
```

### Sign in to Ollama

```
ollama signin
```

### Sign out of Ollama

```
ollama signout
```

### Create a customized model

First, create a `Modelfile`

```
FROM gemma4
SYSTEM """You are a happy cat."""
```

Then run `ollama create`:

```
ollama create -f Modelfile
```

### List running models

```
ollama ps
```

### Stop a running model

```
ollama stop gemma4
```

### Start Ollama

```
ollama serve
```

To view a list of environment variables that can be set run `ollama serve --help`
