由于环境变量不利于配置复杂的内容，新版 FastGPT 采用了 ConfigMap 的形式挂载配置文件，你可以在 `projects/app/data/config.json` 看到默认的配置文件。可以参考 [docker-compose 快速部署](/docs/development/docker/) 来挂载配置文件。

**开发环境下**，你需要将示例配置文件 `config.json` 复制成 `config.local.json` 文件才会生效。

这个配置文件中包含了系统级参数、AI 对话的模型、function 模型等……

以下配置适用于V4.6.6-alpha版本以后

## 特殊模型

### ReRank 接入

请使用 4.6.6-alpha 以上版本，配置文件中的 `reRankModels` 为重排模型，虽然是数组，不过目前仅有第1个生效。

1. [部署 ReRank 模型](/docs/development/custom-models/reranker/)
1. 找到 FastGPT 的配置文件中的 `reRankModels`， 4.6.6 以前是 `ReRankModels`。
2. 修改对应的值：（记得去掉注释）

```json
{
    "reRankModels": [
        {
            "model": "bge-reranker-base", // 随意
            "name": "检索重排-base", // 随意
            "inputPrice": 0,
            "requestUrl": "{{host}}/api/v1/rerank",
            "requestAuth": "安全凭证，已自动补 Bearer"
        }
    ]
}
```
