# Function Description
|
|
The `model-mapper` plugin implements model parameter mapping functionality based on the LLM protocol.
|
|
|
|
# Configuration Fields
|
|
|
|
| Name | Type | Requirement | Default Value | Description |
|
|
| --- | --- | --- | --- | --- |
|
|
| `modelKey` | string | Optional | model | The position of the model parameter in the request body. |
|
|
| `modelMapping` | map of string | Optional | - | AI model mapping table, used to map the model name in the request to the model name supported by the service provider.<br/>1. Supports prefix matching. For example, use "gpt-3-*" to match all names starting with "gpt-3-";<br/>2. Supports using "*" as a key to configure a generic fallback mapping;<br/>3. If the target mapping name is an empty string "", it indicates keeping the original model name. |
|
|
| `enableOnPathSuffix` | array of string | Optional | ["/completions","/embeddings","/images/generations","/audio/speech","/fine_tuning/jobs","/moderations","/image-synthesis","/video-synthesis","/rerank","/messages"] | Only effective for requests with these specific path suffixes. |
|

|
## Effect Description
|
|
|
|
Configuration example:
|
|
|
|
```yaml
|
|
modelMapping:
|
|
'gpt-4-*': "qwen-max"
|
|
'gpt-4o': "qwen-vl-plus"
|
|
'*': "qwen-turbo"
|
|
```
|
|
|
|
After enabling, model parameters starting with `gpt-4-` will be replaced with `qwen-max`, `gpt-4o` will be replaced with `qwen-vl-plus`, and all other models will be replaced with `qwen-turbo`.
|
|
|
|
For example, the original request is:
|
|
|
|
```json
|
|
{
|
|
"model": "gpt-4o",
|
|
"frequency_penalty": 0,
|
|
"max_tokens": 800,
|
|
"stream": false,
|
|
"messages": [{
|
|
"role": "user",
|
|
"content": "What is the github address of the main repository of the higress project"
|
|
}],
|
|
"presence_penalty": 0,
|
|
"temperature": 0.7,
|
|
"top_p": 0.95
|
|
}
|
|
```
|
|
|
|
|
|
After processing by this plugin, the original LLM request body will be modified to:
|
|
|
|
```json
|
|
{
|
|
"model": "qwen-vl-plus",
|
|
"frequency_penalty": 0,
|
|
"max_tokens": 800,
|
|
"stream": false,
|
|
"messages": [{
|
|
"role": "user",
|
|
"content": "What is the github address of the main repository of the higress project"
|
|
}],
|
|
"presence_penalty": 0,
|
|
"temperature": 0.7,
|
|
"top_p": 0.95
|
|
}
|
|
```
