Via OpenRouter

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

fluffbuzz onboard --non-interactive \

  --openrouter-api-key "$OPENROUTER_API_KEY"

Built-in catalog

FluffBuzz 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.

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

OpenRouter routing

When using Arcee models via OpenRouter, the same arcee/* model refs apply. FluffBuzz 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.
