Arcee AI provides access to the Trinity family of mixture-of-experts models through an OpenAI-compatible API. All Trinity models are Apache 2.0 licensed.
Arcee AI models can be accessed directly via the Arcee platform or through OpenRouter.

Getting started
Create an API key at [Arcee AI](https://chat.arcee.ai/).
```bash
openclaw onboard --auth-choice arceeai-api-key
```
```json5
{
agents: {
defaults: {
model: { primary: "arcee/trinity-large-thinking" },
},
},
}
```
Create an API key at [OpenRouter](https://openrouter.ai/keys).
```bash
openclaw onboard --auth-choice arceeai-openrouter
```
```json5
{
agents: {
defaults: {
model: { primary: "arcee/trinity-large-thinking" },
},
},
}
```
The same model refs work for both direct and OpenRouter setups (for example `arcee/trinity-large-thinking`).

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 handles routing transparently based on your auth choice. See the
[OpenRouter provider docs](/providers/openrouter) for OpenRouter-specific
configuration details.
