+  - You want to use Arcee AI with OpenClaw
+  - You need the API key env var or CLI auth choice
+---
+
+[Arcee AI](https://arcee.ai) provides the Trinity family of mixture-of-experts models through an OpenAI-compatible API. All Trinity models are Apache 2.0 licensed. Arcee is an official OpenClaw plugin, not bundled with core, so it needs an install step before onboarding.
+
+Access Arcee models directly through the Arcee platform or through [OpenRouter](/providers/openrouter).

+<AccordionGroup>
+  <Accordion title="Environment note">
+    If the Gateway runs as a daemon (launchd/systemd), make sure `ARCEEAI_API_KEY`
+    (or `OPENROUTER_API_KEY`) is available to that process, for example in
+    `~/.openclaw/.env` or via `env.shellEnv`.
+  </Accordion>
+
+  <Accordion title="OpenRouter routing">
+    When using Arcee models via OpenRouter, the same `arcee/*` model refs apply.
+    OpenClaw routes transparently based on your auth choice. See the
+    [OpenRouter provider docs](/providers/openrouter) for OpenRouter-specific
+    configuration details.
