Getting started
Get an API key
Create an API key in the Cerebras Cloud Console.
Run onboarding
openclaw onboard --auth-choice cerebras-api-keyopenclaw onboard --non-interactive \--auth-choice cerebras-api-key \--cerebras-api-key "$CEREBRAS_API_KEY"export CEREBRAS_API_KEY=csk-...Verify models are available
openclaw models list --provider cerebrasThe list should include all four bundled models. If CEREBRAS_API_KEY is unresolved, openclaw models status --json reports the missing credential under auth.unusableProfiles.
Non-interactive setup
openclaw onboard --non-interactive \ --mode local \ --auth-choice cerebras-api-key \ --cerebras-api-key "$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.

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