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
openclaw onboard --auth-choice cerebras-api-key
openclaw onboard --non-interactive \
--auth-choice cerebras-api-key \
--cerebras-api-key "$CEREBRAS_API_KEY"
export CEREBRAS_API_KEY=csk-...
</CodeGroup>
The list should include all four bundled models. If `CEREBRAS_API_KEY` is unresolved, `openclaw models status --json` reports the missing credential under `auth.unusableProfiles`.
Non-interactive setup
openclaw onboard --non-interactive \
--mode local \
--auth-choice cerebras-api-key \
--cerebras-api-key "$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" },
],
},
},
},
}
