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.

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.
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 for OpenRouter-specific configuration details.
