Is Cerebras Inference free?
OpenAI-compatible inference API with a one-time free trial credit for testing supported high-speed models.
Current free offer summary
New accounts receive $5 in free Cerebras Inference credits. The offer is a one-time trial rather than a recurring daily free tier. Current request and token limits are shown for the account and may vary by plan, project, and model.
What Cerebras Inference does
Cerebras Inference provides an OpenAI-compatible API and browser playground for supported models running on Cerebras hardware. The current official offer gives new accounts $5 in free credits for testing. Cerebras documents rate limits as specific to each plan and project, so FreeAIList does not publish the older one-million-token daily claim.

FreeAIList verdict
A strong trial for developers who want to test unusually fast inference with familiar OpenAI-style tooling. The free amount is modest, but the terms are clearer than the older variable free-tier claims.
Paid plans: The self-service Developer tier uses pay-per-token pricing, accepts added funds starting at $10, and provides higher limits and processing priority than the trial.
