```bash} openclaw onboard --auth-choice cerebras-api-key ```

Verify models are available

```bash} openclaw models list --provider cerebras ```

Non-Interactive Setup


bash
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 for the public OpenAI-compatible endpoint:

Model ref	Name	Notes
text `cerebras/zai-glm-4.7`	Z.ai GLM 4.7	Default model; preview reasoning model
text `cerebras/gpt-oss-120b`	GPT OSS 120B	Production reasoning model
text `cerebras/qwen-3-235b-a22b-instruct-2507`	Qwen 3 235B Instruct	Preview non-reasoning model
text `cerebras/llama3.1-8b`	Llama 3.1 8B	Production speed-focused model

warning

Cerebras marks `zai-glm-4.7` and `qwen-3-235b-a22b-instruct-2507` as preview models, and `llama3.1-8b` / `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.

Manual Config

The bundled plugin usually means you only need the API key. Use explicit

text

models.providers.cerebras

config when you want to override model metadata:


json5
{
  env: { CEREBRAS_API_KEY: "sk-..." },
  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" },
        ],
      },
    },
  },
}

note

If the Gateway runs as a daemon (launchd/systemd), make sure `CEREBRAS_API_KEY` is available to that process, for example in `~/.openclaw/.env` or through `env.shellEnv`.
