+## Telemetry
+
+Directus can send AI Assistant traces to [Langfuse](https://langfuse.com) or [Braintrust](https://braintrust.dev) for observability — monitor usage, latency, token costs, and full request/response content.
+
+Set the following environment variables to enable telemetry:
+
+```ini
+AI_TELEMETRY_ENABLED=true
+AI_TELEMETRY_PROVIDER=langfuse # or braintrust
+```
+
+### Langfuse
+
+```ini
+AI_TELEMETRY_PROVIDER=langfuse
+LANGFUSE_SECRET_KEY=sk-lf-...
+LANGFUSE_PUBLIC_KEY=pk-lf-...
+LANGFUSE_BASE_URL=https://cloud.langfuse.com # optional, default shown
