​
Built-In Catalog

OpenClaw ships a static Cerebras catalog for the public OpenAI-compatible endpoint:
Model refNameNotes
cerebras/zai-glm-4.7Z.ai GLM 4.7Default model; preview reasoning model
cerebras/gpt-oss-120bGPT OSS 120BProduction reasoning model
cerebras/qwen-3-235b-a22b-instruct-2507Qwen 3 235B InstructPreview non-reasoning model
cerebras/llama3.1-8bLlama 3.1 8BProduction speed-focused model
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 models.providers.cerebras config when you want to override model metadata: 
{
  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" },
        ],
      },
    },
  },
}
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.
