FAQ

Questions about Cerebras Chat Completion.

What does the Cerebras Chat Completion action do in Cerebras?

Runs chat completion against Cerebras's custom-hardware-served Llama models. Extreme speed (1000-2000+ tokens/sec) is the value — for multi-step agent workflows, the latency win stacks meaningfully across calls.

What inputs does Cerebras Chat Completion require?

Required: Model, User Message. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Cerebras returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Cerebras Chat Completion support batch operations?

Yes. Run Cerebras Chat Completion inside a Loop node to process arrays. Tiny Command handles Cerebras's rate limits automatically so you don't have to throttle manually.
