-# Higress Helm Chart
-
-Installs the cloud-native gateway [Higress](http://higress.io/)
-
-## Get Repo Info
-
-```console
-helm repo add higress.io https://higress.io/helm-charts
-helm repo update
-```
-
-_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._
-
-## Installing the Chart
-
-To install the chart with the release name `higress`:
-
-```console
-helm install higress -n higress-system higress.io/higress --create-namespace --render-subchart-notes
-```
-
-## Uninstalling the Chart
-
-To uninstall/delete the higress deployment:
-
-```console
-helm delete higress -n higress-system
-```
-
-The command removes all the Kubernetes components associated with the chart and deletes the release.
-
-## Configuration
-
-| **Parameter** | **Description** | **Default** |
-|---|---|---|
-| **Global Parameters** |  |  |
-| global.local | Set to `true` if installing to a local K8s cluster (e.g.: Kind, Rancher Desktop, etc.) | false |
-| global.ingressClass | [IngressClass](https://kubernetes.io/zh-cn/docs/concepts/services-networking/ingress/#ingress-class) which is used to filter Ingress resources Higress Controller watches.<br />If there are multiple gateway instances deployed in the cluster, this parameter can be used to distinguish the scope of each gateway instance.<br />There are some special cases for special IngressClass values:<br />1. If set to "nginx", Higress Controller will watch Ingress resources with the `nginx` IngressClass or without any Ingress class.<br />2. If set to empty, Higress Controller will watch all Ingress resources in the K8s cluster. | higress |
-| global.watchNamespace | If not empty, Higress Controller will only watch resources in the specified namespace. When isolating different business systems using K8s namespace, if each namespace requires a standalone gateway instance, this parameter can be used to confine the Ingress watching of Higress within the given namespace. | "" |
-| global.disableAlpnH2 | Whether to disable HTTP/2 in ALPN | true |
-| global.enableStatus | If `true`, Higress Controller will update the `status` field of Ingress resources.<br />When migrating from Nginx Ingress, in order to avoid `status` field of Ingress objects being overwritten, this parameter needs to be set to false, so Higress won't write the entry IP to the `status` field of the corresponding Ingress object. | true |
-| global.enableIstioAPI | If `true`, Higress Controller will monitor istio resources as well | false |
-| global.enableGatewayAPI | If `true`, Higress Controller will monitor Gateway API resources as well | false |
-| global.istioNamespace | The namespace istio is installed to | istio-system |
-| **Core Paramters** |  |  |
-| higress-core.gateway.replicas | Number of Higress Gateway pods | 2 |
-| higress-core.controller.replicas | Number of Higress Controller pods | 1 |
-| **Console Paramters** |  |  |
-| higress-console.replicaCount | Number of Higress Console pods | 1 |
-| higress-console.service.type | K8s service type used by Higress Console | ClusterIP |
-| higress-console.domain | Domain used to access Higress Console | console.higress.io |
-| higress-console.tlsSecretName | Name of Secret resource used by TLS connections. | "" |
-| higress-console.web.login.prompt | Prompt message to be displayed on the login page | "" |
-| higress-console.admin.password.value | If not empty, the admin password will be configured to the specified value. | "" |
-| higress-console.admin.password.length | The length of random admin password generated during installation. Only works when `higress-console.admin.password.value` is not set. | 8 |
-| higress-console.o11y.enabled | If `true`, o11y suite (Grafana + Promethues) will be installed. | false |
-| higress-console.pvc.rwxSupported | Set to `false` when installing to a standard K8s cluster and the target cluster doesn't support the ReadWriteMany access mode of PersistentVolumeClaim. | true |
+## Higress for Kubernetes
+
+Higress is a cloud-native api gateway based on Alibaba's internal gateway practices.
+
+Powered by Istio and Envoy, Higress realizes the integration of the triple gateway architecture of traffic gateway, microservice gateway and security gateway, thereby greatly reducing the costs of deployment, operation and maintenance.
+
+## Setup Repo Info

+## Higress for Kubernetes
+
+Higress is a cloud-native api gateway based on Alibaba's internal gateway practices.
+
+Powered by Istio and Envoy, Higress realizes the integration of the triple gateway architecture of traffic gateway, microservice gateway and security gateway, thereby greatly reducing the costs of deployment, operation and maintenance.
+
+## Setup Repo Info
+
+```console
+helm repo add higress.io https://higress.io/helm-charts
+helm repo update
+```
+
+## Install
+
+To install the chart with the release name `higress`:
+
+```console
+helm install higress -n higress-system higress.io/higress --create-namespace --render-subchart-notes
+```
+
+## Uninstall
+
+To uninstall/delete the higress deployment:
+
+```console
+helm delete higress -n higress-system
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Parameters
+
+{{ template "chart.valuesSection" . }}

+## 效果说明

+如下配置
+
+```yaml
+modelMapping:
+  'gpt-4-*': "qwen-max"
+  'gpt-4o': "qwen-vl-plus"
+  '*': "qwen-turbo"
+```
+
+开启后，`gpt-4-` 开头的模型参数会被改写为 `qwen-max`, `gpt-4o` 会被改写为 `qwen-vl-plus`，其他所有模型会被改写为 `qwen-turbo`
+
+例如原本的请求是：
+
+```json
+{
+    "model": "gpt-4o",
+    "frequency_penalty": 0,
+    "max_tokens": 800,
+    "stream": false,
+    "messages": [{
+        "role": "user",
+        "content": "higress项目主仓库的github地址是什么"
+    }],
+    "presence_penalty": 0,
+    "temperature": 0.7,
+    "top_p": 0.95
+}
+```
+
+
+经过这个插件后，原始的 LLM 请求体将被改成：
+
+```json
+{
+    "model": "qwen-vl-plus",
+    "frequency_penalty": 0,
+    "max_tokens": 800,
+    "stream": false,
+    "messages": [{
+        "role": "user",
+        "content": "higress项目主仓库的github地址是什么"
+    }],
+    "presence_penalty": 0,
+    "temperature": 0.7,
+    "top_p": 0.95
+}
+```

+## Function Description
+The `model-mapper` plugin implements the functionality of routing based on the model parameter in the LLM protocol.

+
+## Runtime Properties
+
+Plugin execution phase: Authentication phase
+Plugin execution priority: 800
+
+## Effect Description
+
+With the following configuration:
+
+```yaml
+modelMapping:
+  'gpt-4-*': "qwen-max"
+  'gpt-4o': "qwen-vl-plus"
+  '*': "qwen-turbo"
+```
+
+After enabling, model parameters starting with `gpt-4-` will be rewritten to `qwen-max`, `gpt-4o` will be rewritten to `qwen-vl-plus`, and all other models will be rewritten to `qwen-turbo`.
+
+For example, if the original request was:
+
+```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 for 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 for the higress project?"
+    }],
+    "presence_penalty": 0,
+    "temperature": 0.7,
+    "top_p": 0.95
+}
+```

+**Configuration Information**
+Add custom json schema configuration
+```yaml
+jsonResp:
+  enable: true
+  jsonSchema:
+    title: WeatherSchema
+    type: object
+    properties:
+      location:
+        type: string
+        description: city name.
+      weather:
+        type: string
+        description: weather conditions.
+      temperature:
+        type: string
+        description: temperature.
+      update_time:
+        type: string
+        description: the update time of data.
+    required:
+      - location
+      - weather
+      - temperature
+    additionalProperties: false
+```
+
+**Request Example**
+
+```shell
+curl 'http://<replace with gateway public IP>/api/openai/v1/chat/completions' \
+-H 'Accept: application/json, text/event-stream' \
+-H 'Content-Type: application/json' \
