Providers

Cerebras

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

Property Value
Provider id cerebras
Plugin bundled, enabledByDefault: true
Auth env var CEREBRAS_API_KEY
Onboarding flag --auth-choice cerebras-api-key
Direct CLI flag --cerebras-api-key <key>
API OpenAI-compatible (openai-completions)
Base URL https://api.cerebras.ai/v1
Default model cerebras/zai-glm-4.7

Getting started

  • Get an API key

    Create an API key in the Cerebras Cloud Console.

  • Run onboarding

    openclaw onboard --auth-choice cerebras-api-key
    
    openclaw onboard --non-interactive \
    --auth-choice cerebras-api-key \
    --cerebras-api-key "$CEREBRAS_API_KEY"
    
    export CEREBRAS_API_KEY=csk-...
    
  • 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.

    Model ref Name Reasoning Notes
    cerebras/zai-glm-4.7 Z.ai GLM 4.7 yes Default model; preview reasoning model
    cerebras/gpt-oss-120b GPT OSS 120B yes Production reasoning model
    cerebras/qwen-3-235b-a22b-instruct-2507 Qwen 3 235B Instruct no Preview non-reasoning model
    cerebras/llama3.1-8b Llama 3.1 8B no Production speed-focused model

    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" },
            ],
          },
        },
      },
    }
