## Langchain Provider Installation

> **Important**: You will need to install additional provider packages for the specific AI models you want to use. LangChain requires separate packages for each provider.

When creating a new LangChain model, LaunchDarkly uses an AI Config and the `initChatModel` provided by LangChain to create a model instance. You should install all LangChain providers for each provider you plan to use in your AI Config to ensure they can be properly instantiated.

### Installing a LangChain Provider

To use specific AI models, install the corresponding provider package:

```shell
# For OpenAI models
npm install @langchain/openai --save
# or
yarn add @langchain/openai
```

For a complete list of available providers and installation instructions, see the [LangChain JavaScript Integrations documentation](https://js.langchain.com/docs/integrations/chat/).

## Advanced Usage

For more control, you can use the LangChain provider package directly with LaunchDarkly configurations:

## Vercel AI Provider Installation

> **Important**: You will need to install additional provider packages for the specific AI models you want to use. The Vercel AI SDK requires separate packages for each provider.

When creating a new Vercel AI model, LaunchDarkly uses an AI Config and the Vercel AI SDK's provider system to create a model instance. You should install all Vercel AI provider packages for each provider you plan to use in your AI Config to ensure they can be properly instantiated.

### Installing a Vercel AI Provider

To use specific AI models, install the corresponding provider package:

```shell
# For OpenAI models
npm install @ai-sdk/openai --save
# or
yarn add @ai-sdk/openai
```

For a complete list of available providers and installation instructions, see the [Vercel AI SDK Providers documentation](https://sdk.vercel.ai/providers).
