+# OpenWebUI
+
+OpenWebUI is exposed at `https://openwebui.noxxos.nl` and connects to the
+OpenAI-compatible llama.cpp endpoint at `http://framework-llm:8080/v1`.
+
+## Authentik
+
+Create an Authentik OAuth2/OIDC provider and application with slug
+`open-webui`.
+
+Allowed redirect URI:
+
+```text
+https://openwebui.noxxos.nl/oauth/oidc/callback
+```
+
+Create the OIDC client secret in Kubernetes before syncing the app:
+
+```bash
+kubectl create namespace open-webui
+kubectl -n open-webui create secret generic open-webui-oidc \
+  --from-literal=client-id='<authentik-client-id>' \
+  --from-literal=client-secret='<authentik-client-secret>'
