# How to use Ollama in my system?

To use Ollama on your system, follow these quick steps:

## 1. Install Ollama

Download from:

[Ollama Official Website](https://ollama.com/)

Available for:

- Windows
- macOS
- Linux

After installation, verify:

```plaintext
ollama --version
```

## 2. Pull a Model

Example:

```plaintext
ollama pull llama3
```

Other popular models:

- `mistral`
- `codellama`
- `phi`
- `gemma`

## 3. Run a Model

```plaintext
ollama run llama3
```

Now you can chat locally in terminal.

Example:

```plaintext
>>> Explain microservices
```

## 4. Use via API

Ollama automatically starts a local API server.

Default URL:

```plaintext
http://localhost:11434
```

Example API call:

```javascript
curl http://localhost:11434/api/generate -d '{
  "model": "llama3",
  "prompt": "What is ASP.NET Core?"
}'
```

## 5. Use in C#

Example with `HttpClient`:

```cs
var client = new HttpClient();

var json = """
{
  "model": "llama3",
  "prompt": "Explain SQL indexing"
}
""";

var content = new StringContent(
    json,
    Encoding.UTF8,
    "application/json");

var response = await client.PostAsync(
    "http://localhost:11434/api/generate",
    content);

var result = await response.Content.ReadAsStringAsync();

Console.WriteLine(result);
```

## 6. List Installed Models

```plaintext
ollama list
```

## 7. Remove a Model

```plaintext
ollama rm llama3
```

## Popular Usage

Developers commonly use Ollama for:

- Local AI chatbots
- Code assistants
- RAG applications
- Document summarization
- Offline AI apps

AI APIs in ASP.NET Core/Python/Node.js

## Recommended Models

| Use Case | Model |
| --- | --- |
| General Chat | llama3 |
| Coding | codellama |
| Lightweight | phi |
| Fast Responses | mistral |

## Minimum System Recommendation

| Component | Recommended |
| --- | --- |
| RAM | 16GB+ |
| GPU | Optional but helpful |
| OS | Windows/Linux/macOS |

Runs on CPU too, but GPU is much faster.
