Arcee AI

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.

Property	Value
Provider	`arcee`
Auth	`ARCEEAI_API_KEY` (direct) or `OPENROUTER_API_KEY` (via OpenRouter)
API	OpenAI-compatible

Getting started

Direct (Arcee platform)
Via OpenRouter

Get an API key

Create an API key at Arcee AI.

Run onboarding

velaclaw 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

velaclaw 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 (for example arcee/trinity-large-thinking).

Non-interactive setup

Direct (Arcee platform)
Via OpenRouter

velaclaw onboard --non-interactive \
  --mode local \
  --auth-choice arceeai-api-key \
  --arceeai-api-key "$ARCEEAI_API_KEY"

velaclaw onboard --non-interactive \
  --mode local \
  --auth-choice arceeai-openrouter \
  --openrouter-api-key "$OPENROUTER_API_KEY"

Built-in catalog

Velaclaw currently ships this bundled Arcee catalog:

Model ref	Name	Input	Context	Cost (in/out per 1M)	Notes
`arcee/trinity-large-thinking`	Trinity Large Thinking	text	256K	$0.25 /$ 0.90	Default model; reasoning enabled
`arcee/trinity-large-preview`	Trinity Large Preview	text	128K	$0.25 /$ 1.00	General-purpose; 400B params, 13B active
`arcee/trinity-mini`	Trinity Mini 26B	text	128K	$0.045 /$ 0.15	Fast and cost-efficient; function calling

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

Supported features

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 ~/.velaclaw/.env or via env.shellEnv).

OpenRouter routing

When using Arcee models via OpenRouter, the same arcee/* model refs apply. Velaclaw handles routing transparently based on your auth choice. See the OpenRouter provider docs for OpenRouter-specific configuration details.

OpenRouter

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