# Cerebras LLM

> Use Cerebras-hosted gpt-oss-120b as the LLM for an Edesy voice agent on the default runtime. Set it through the API or ask us to switch it.

Cerebras hosts open models on its own inference hardware. The default Edesy runtime supports it with `gpt-oss-120b` as the default model. Cerebras is not yet in the dashboard model picker, so set it on an agent through the API or ask support to switch the agent for you.

## At a glance

| Item | Value |
|------|-------|
| Provider ID | `cerebras` |
| Runtime | Default runtime |
| Default model | `gpt-oss-120b` |
| Dashboard picker | Not listed yet. Set it through the API or ask support |
| Your own key (BYOK) | Supported |

Note: the model ID differs from Groq's for the same model. Cerebras uses `gpt-oss-120b`; Groq uses `openai/gpt-oss-120b`.

## Set it up through the API

```bash
curl -X PATCH https://voice-agent.edesy.in/api/v1/agents/AGENT_ID \
  -H "Authorization: Bearer $EDESY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "llmProvider": "cerebras", "llmModel": "gpt-oss-120b" }'
```

Your API key needs the `agents:write` scope. See [authentication and scopes](https://edesy.in/docs/voice-agent/api/authentication).

## FAQs

**Why is Cerebras not in the dashboard?**
The runtime supports it, but the model picker does not list it yet. Agents set to Cerebras through the API run normally.

**Will editing the agent in the dashboard reset the model?**
Check the model field after saving in the dashboard. If it changed, set it again through the API or ask support.

**Does Cerebras support function calling?**
Yes, through the OpenAI-compatible API. Test your tools before going live.
