Cerebras provides high-speed OpenAI-compatible inference on custom inference hardware. OpenClaw includes a bundled Cerebras provider plugin with a static four-model catalog.

​
Getting started

1

Get an API key

Create an API key in the Cerebras Cloud Console.
2

Run onboarding

openclaw onboard --auth-choice cerebras-api-key
3

Verify models are available

openclaw models list --provider cerebras
The list should include all four bundled models. If CEREBRAS_API_KEY is unresolved, openclaw models status --json reports the missing credential under auth.unusableProfiles.

​
Non-interactive setup

openclaw onboard --non-interactive \
  --mode local \
  --auth-choice cerebras-api-key \
  --cerebras-api-key "$CEREBRAS_API_KEY"

​
Built-in catalog

OpenClaw ships a static Cerebras catalog that mirrors the public OpenAI-compatible endpoint. All four models share a 128k context and 8,192 max-output tokens.

Cerebras marks zai-glm-4.7 and qwen-3-235b-a22b-instruct-2507 as preview models, and llama3.1-8b plus qwen-3-235b-a22b-instruct-2507 are documented for deprecation on May 27, 2026. Check Cerebras’ supported-models page before relying on them for production workloads.

Manual config

The bundled plugin usually means you only need the API key. Use explicit models.providers.cerebras config when you want to override model metadata or run in mode: "merge" against the static catalog: 
{
  env: { CEREBRAS_API_KEY: "csk-..." },
  agents: {
    defaults: {
      model: { primary: "cerebras/zai-glm-4.7" },
    },
  },
  models: {
    mode: "merge",
    providers: {
      cerebras: {
        baseUrl: "https://api.cerebras.ai/v1",
        apiKey: "${CEREBRAS_API_KEY}",
        api: "openai-completions",
        models: [
          { id: "zai-glm-4.7", name: "Z.ai GLM 4.7" },
          { id: "gpt-oss-120b", name: "GPT OSS 120B" },
        ],
      },
    },
  },
}
If the Gateway runs as a daemon (launchd, systemd, Docker), make sure CEREBRAS_API_KEY is available to that process — for example in ~/.openclaw/.env or through env.shellEnv. A key sitting only in ~/.profile will not help a managed service unless the env is imported separately.
