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.

Install plugin

Getting started

1

Get an API key

Create an API key at Arcee AI.
2

Run onboarding

3

Set a default model

Non-interactive setup

Direct Arcee catalog

The onboarding preset sets arcee/trinity-large-thinking as the default model.

OpenRouter catalog

OpenRouter onboarding exposes arcee/trinity-large-preview and arcee/trinity-large-thinking. OpenClaw keeps those provider-qualified model refs in config and sends OpenRouter’s canonical arcee-ai/* runtime ids. Trinity Mini is no longer served by OpenRouter; use the direct Arcee API for that model.

Supported features

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.
OpenRouter uses the same arcee/trinity-large-thinking OpenClaw model ref. OpenClaw routes it with the canonical arcee-ai/trinity-large-thinking OpenRouter runtime id. See the OpenRouter provider docs for OpenRouter-specific configuration details.

OpenRouter

Access Arcee models and many others through a single API key.
