## Overview

Continue is an open-source AI coding assistant that works as an extension for VS Code and JetBrains IDEs. It provides chat, autocomplete, and code editing powered by LLMs. Connect it to ModelStack to access multiple model providers through one interface.

## Prerequisites

- VS Code or JetBrains IDE installed
- ModelStack API key from your [dashboard](https://modelstack.cc/dashboard/api-keys)

## Installation

### VS Code

1. Open VS Code
2. Go to Extensions (`Cmd+Shift+X` or `Ctrl+Shift+X`)
3. Search for "Continue"
4. Click **Install**

### JetBrains

1. Open your JetBrains IDE (IntelliJ, PyCharm, etc.)
2. Go to **Settings** → **Plugins**
3. Search for "Continue"
4. Click **Install** and restart

## Configuration

### Step 1: Open Continue Config

1. Click the Continue icon in your sidebar
2. Click the gear icon (⚙️) to open settings
3. Select **Edit config.json**

### Step 2: Add ModelStack Provider

Add this configuration to your `config.json`:

```json
{
  "models": [
    {
      "title": "Claude Sonnet 4.6",
      "provider": "openai",
      "model": "claude-sonnet-4-6",
      "apiKey": "your_modelstack_api_key",
      "apiBase": "https://api.modelstack.cc/v1"
    },
    {
      "title": "GPT-4o",
      "provider": "openai",
      "model": "gpt-4o",
      "apiKey": "your_modelstack_api_key",
      "apiBase": "https://api.modelstack.cc/v1"
    }
  ]
}
```

Replace `your_modelstack_api_key` with your actual API key.

### Step 3: Select Model

In the Continue chat interface, use the model dropdown to switch between configured models.

## Usage Examples

**Chat**: Ask questions about your codebase

```
@codebase How does authentication work?
```

**Edit**: Select code and ask Continue to modify it

```
/edit Add error handling to this function
```

**Autocomplete**: Continue provides inline suggestions as you type (if enabled in settings)

## Troubleshooting

**Issue**: "Failed to connect to API"

**Solution**: Verify the `apiBase` is exactly `https://api.modelstack.cc/v1` (no trailing slash) and your API key is valid.

**Issue**: Autocomplete not working

**Solution**: Check that autocomplete is enabled in Continue settings and you have sufficient credits in your [ModelStack account](https://modelstack.cc/dashboard/billing).

## Advanced Configuration

### Multiple Models

You can configure multiple models for different use cases:

```json
{
  "models": [
    {
      "title": "Fast (Haiku)",
      "provider": "openai",
      "model": "claude-haiku-4-5",
      "apiKey": "your_key",
      "apiBase": "https://api.modelstack.cc/v1"
    },
    {
      "title": "Powerful (Opus)",
      "provider": "openai",
      "model": "claude-opus-4-6",
      "apiKey": "your_key",
      "apiBase": "https://api.modelstack.cc/v1"
    }
  ]
}
```
