# Model Providers

When deploying LobeChat, a rich set of environment variables related to model service providers is provided, allowing you to easily define the model service providers to be enabled in LobeChat.

## OpenAI

### `ENABLED_OPENAI`

- Type：Optional
- Description：Enables OpenAI as a model provider by default, turns off the OpenAI service when set to `0`
- Default：`1`
- Example：`0`

### `OPENAI_API_KEY`

- Type: Required
- Description: This is the API key you applied for on the OpenAI account page, you can check it out [here](https://platform.openai.com/api-keys)
- Default: -
- Example: `sk-xxxxxx...xxxxxx`

### `OPENAI_PROXY_URL`

- Type: Optional
- Description: If you manually configure the OpenAI interface proxy, you can use this configuration item to override the default OpenAI API request base URL
- Default: `https://api.openai.com/v1`
- Example: `https://api.chatanywhere.cn` or `https://aihubmix.com/v1`

<Callout type={'warning'}>
  Please check the request suffix of your proxy service provider. Some proxy service providers may
  add `/v1` to the request suffix, while others may not. If you find that the AI returns an empty
  message during testing, try adding the `/v1` suffix and retry.
</Callout>

<Callout type={'info'}>
  Whether to fill in `/v1` is closely related to the model service provider. For example, the
  default address of openai is `api.openai.com/v1`. If your proxy forwards the `/v1` interface, you
  can simply fill in `proxy.com`. However, if the model service provider directly forwards the
  `api.openai.com` domain, then you need to add `/v1` to the URL yourself.
</Callout>

### `OPENAI_MODEL_LIST`

- Type: Optional
- Description: Used to control the model list, use `+` to add a model, use `-` to hide a model, use `model_name=display_name` to customize the display name of a model, separated by commas. Definition syntax rules see [model-list][model-list]
- Default: `-`
- Example: `+qwen-7b-chat,+glm-6b,-gpt-3.5-turbo,gpt-4-0125-preview=gpt-4-turbo`

The above example adds `qwen-7b-chat` and `glm-6b` to the model list, removes `gpt-3.5-turbo` from the list, and displays the name of `gpt-4-0125-preview` as `gpt-4-turbo`. If you want to disable all models first and then enable specific models, you can use `-all,+gpt-3.5-turbo`, which means only `gpt-3.5-turbo` will be enabled.

You can find all current model names in [modelProviders](https://github.com/lobehub/lobe-chat/tree/main/src/config/modelProviders).
