Arcee AI

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.

Property	Value
Provider	`arcee`
Auth	`ARCEEAI_API_KEY` (direct) or `OPENROUTER_API_KEY` (via OpenRouter)
API	OpenAI-compatible
Base URL	`https://api.arcee.ai/api/v1` (direct) or `https://openrouter.ai/api/v1` (OpenRouter)

Install plugin

openclaw plugins install @openclaw/arcee-provider

Installation applies to a running Gateway automatically; otherwise it takes effect on the next startup. See Apply changes and inspect.

Getting started

Direct (Arcee platform)
Via OpenRouter

Get an API key

Create an API key at Arcee AI.

Run onboarding

openclaw onboard --auth-choice arceeai-api-key

Set a default model

{
  agents: {
    defaults: {
      model: { primary: "arcee/trinity-large-thinking" },
    },
  },
}

Get an API key

Create an API key at OpenRouter.

Run onboarding

openclaw onboard --auth-choice arceeai-openrouter

Set a default model

{
  agents: {
    defaults: {
      model: { primary: "arcee/trinity-large-thinking" },
    },
  },
}

The same model refs work for both direct and OpenRouter setups.

Non-interactive setup

Direct (Arcee platform)
Via OpenRouter

openclaw onboard --non-interactive --accept-risk --skip-health \
  --mode local \
  --auth-choice arceeai-api-key \
  --arceeai-api-key "$ARCEEAI_API_KEY"

openclaw onboard --non-interactive --accept-risk --skip-health \
  --mode local \
  --auth-choice arceeai-openrouter \
  --openrouter-api-key "$OPENROUTER_API_KEY"

Ordinary onboarding saves the connection without adding catalog rows to models.providers.arcee.models. Existing rows and model aliases stay in place. With models.mode: "replace", onboarding also adds the route’s catalog defaults because that mode disables automatic discovery. The public applyArceeConfig and applyArceeOpenRouterConfig helpers still add catalog defaults in every mode.

Direct Arcee catalog

Model ref	Name	Input	Context	Max output	Cost (in/out per 1M)	Tools	Notes
`arcee/trinity-large-thinking`	Trinity Large Thinking	text	256K	80K	$0.25 /$ 0.90	No	Default model; extended thinking
`arcee/trinity-large-preview`	Trinity Large Preview	text	128K	16K	$0.25 /$ 1.00	Yes	General-purpose; 400B params, 13B active
`arcee/trinity-mini`	Trinity Mini 26B	text	128K	80K	$0.045 /$ 0.15	Yes	Fast and cost-efficient; function calling

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

Feature	Supported
Streaming	Yes
Tool use / function calling	Yes (Trinity Mini, Trinity Large Preview)
Structured output (JSON mode and JSON schema)	Yes
Extended thinking	Yes (Trinity Large Thinking; tools disabled)

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.

OpenRouter routing

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.
