   Cerebras Inference is a pure REST API with official Python/Node SDKs, OpenAI-compatible endpoints, and a Batch API for asynchronous request processing—all of which are inherently headless and scriptable for CI/automation pipelines (cerebras-docs-1, cerebras-docs-3, cerebras-docs-8, cerebras-docs-17, cerebras-gh-2).

   Cerebras Inference~partialcommunity4/10

   Cerebras publishes a public pricing page with self-serve signup, free credits, and tiered self-serve pricing ($10 minimum, 10x rate limits), showing pricing information is not gated behind a sales call for the basic tier (cerebras-docs-13,14,20,25,26). However, none of the evidence shows an actual published per-token $/M-token rate for each hosted model, and one pricing-related doc references access via 'partner APIs' plus a community comment explicitly wonders whether trying the cloud is possible without contacting sales, suggesting the full price list isn't clearly self-evident. Missing for 10: an explicit per-model per-token price table, confirmation that all hosted models (not just self-serve tiers) have listed rates, and independent corroboration that no sales contact is needed to see model-level pricing.
