+
+LangChain.js supports the Moonshot AI family of models.
+
+https://platform.moonshot.cn/docs/intro
+
+## Setup
+
+You'll need to sign up for an Moonshot API key and set it as an environment variable named `MOONSHOT_API_KEY`
+
+https://platform.moonshot.cn/console
+
+You'll also need to install the following dependencies:
+
+import IntegrationInstallTooltip from "@mdx_components/integration_install_tooltip.mdx";
+
+<IntegrationInstallTooltip></IntegrationInstallTooltip>
+
+```bash npm2yarn
+npm install @langchain/community
+```
+
+## Usage
+
+Here's an example:
+
+import Moonshot from "@examples/models/chat/integration_moonshot.ts";
+
+<CodeBlock language="typescript">{Moonshot}</CodeBlock>
