+LangChain supports chat models hosted by [Deep Infra](https://deepinfra.com/) through the `ChatDeepInfra` wrapper.
+First, you'll need to install the `@langchain/community` package:
+
+import IntegrationInstallTooltip from "@mdx_components/integration_install_tooltip.mdx";
+
+<IntegrationInstallTooltip></IntegrationInstallTooltip>
+
+```bash npm2yarn
+npm install @langchain/community
+```
+
+You'll need to obtain an API key and set it as an environment variable named `DEEPINFRA_API_TOKEN`
+(or pass it into the constructor), then call the model as shown below:
+
+import Example from "@examples/models/chat/integration_deepinfra.ts";
