Proprietary

Proprietary cloud inference on custom wafer-scale hardware, reachable only through an API. The inference page offers managed API access with no source or weights release, and the Inference Terms and Conditions grant nothing more than a non-exclusive, limited, non-transferable and non-sublicensable right to access the hosted services.

  Cerebras Inference is a hosted cloud service (tiers: Free Trial with "Get API Key", Developer pay-per-token, Enterprise), with "OpenAI API compatibility" advertised as the integration path; a full-text read of the page finds no source repository, no downloadable weights and no self-hostable implementation - the Enterprise tier's "custom model weights" refers to customer-supplied weights served on Cerebras hardware, not a weights release.
