# Higress Auto Router

Configure automatic model routing using the get-ai-gateway.sh CLI tool for intelligent model selection based on message content triggers.

## Prerequisites

- Higress AI Gateway running (container name: `higress-ai-gateway`)
- get-ai-gateway.sh script downloaded

## CLI Commands

### Add a Routing Rule

```bash
./get-ai-gateway.sh route add --model <model-name> --trigger "<trigger-phrases>"
```

**Options:**
- `--model MODEL` (required): Target model to route to
- `--trigger PHRASE`: Trigger phrase(s), separated by `|` (e.g., `"深入思考|deep thinking"`)
- `--pattern REGEX`: Custom regex pattern (alternative to `--trigger`)

**Examples:**

```bash
# Route complex reasoning to Claude
./get-ai-gateway.sh route add \
  --model claude-opus-4.5 \
  --trigger "深入思考|deep thinking"

# Route coding tasks to Qwen Coder
./get-ai-gateway.sh route add \
  --model qwen-coder \
  --trigger "写代码|code:|coding:"

# Route creative writing
./get-ai-gateway.sh route add \
  --model gpt-4o \
  --trigger "创意写作|creative:"

# Use custom regex pattern
./get-ai-gateway.sh route add \
  --model deepseek-chat \
  --pattern "(?i)^(数学题|math:)"
```

### List Routing Rules

```bash
./get-ai-gateway.sh route list
```

Output:
```
Default model: qwen-turbo

ID   Pattern                                  Model               
----------------------------------------------------------------------
0    (?i)^(深入思考|deep thinking)             claude-opus-4.5     
1    (?i)^(写代码|code:|coding:)               qwen-coder          
```

### Remove a Routing Rule

```bash
./get-ai-gateway.sh route remove --rule-id <id>
```

**Example:**
```bash
# Remove rule with ID 0
./get-ai-gateway.sh route remove --rule-id 0
```

## Common Trigger Mappings

| Scenario | Suggested Triggers | Recommended Model |
|----------|-------------------|-------------------|
| Complex reasoning | `深入思考\|deep thinking` | claude-opus-4.5, o1 |
| Coding tasks | `写代码\|code:\|coding:` | qwen-coder, deepseek-coder |
| Creative writing | `创意写作\|creative:` | gpt-4o, claude-sonnet |
| Translation | `翻译:\|translate:` | gpt-4o, qwen-max |
| Math problems | `数学题\|math:` | deepseek-r1, o1-mini |
| Quick answers | `快速回答\|quick:` | qwen-turbo, gpt-4o-mini |

## Usage Flow

1. **User Request:** "我希望在解决困难问题时路由到claude-opus-4.5"

2. **Execute CLI:**
   ```bash
   ./get-ai-gateway.sh route add \
     --model claude-opus-4.5 \
     --trigger "深入思考|deep thinking"
   ```

3. **Response to User:**
   ```
   ✅ 自动路由配置完成！
   
   触发方式：以 "深入思考" 或 "deep thinking" 开头
   目标模型：claude-opus-4.5
   
   使用示例：
   - 深入思考 这道算法题应该怎么解？
   - deep thinking What's the best architecture?
   
   提示：确保请求中 model 参数为 'higress/auto'
   ```

## How Auto-Routing Works

1. User sends request with `model: "higress/auto"`
2. Higress checks message content against routing rules
3. If a trigger pattern matches, routes to the specified model
4. If no match, uses the default model (e.g., `qwen-turbo`)

## Configuration File

Rules are stored in the container at:
```
/data/wasmplugins/model-router.internal.yaml
```

The CLI tool automatically:
- Edits the configuration file
- Triggers hot-reload (no container restart needed)
- Validates YAML syntax

## Error Handling

- **Container not running:** Start with `./get-ai-gateway.sh start`
- **Rule ID not found:** Use `route list` to see valid IDs
- **Invalid model:** Check configured providers in Higress Console
