Arithmetic, labelled estimate: USD 5 / (USD 0.75 per 1M output) = 6.67M output tokens if the credit were spent on output alone; at a 3:1 input-to-output split, USD 5 buys about 3.8M tokens of mixed traffic. The contradiction between the FAQ and the model pages is the real finding for a future reader: a session that reads only the model page records a free tier that the FAQ denies in as many words. See also the SambaNova record in a10-repos, the same pattern of a stale sub-page describing a withdrawn free tier.","extras":{"facets":{"class":"refutation","free_tier_kind":"trial-credit","shape":{"vcpu":null,"ram_gib":null,"gpu_class":"wafer-scale WSE","gpu_count":null}}}},"claims":[{"path":"$.free_tier","kind":"has-free-tier","num":1.0,"unit":null,"per":null,"currency":null,"usd":null,"fx_date":null,"parse":"ok"},{"path":"$.free_tier.stated","kind":"free-quota","num":30.0,"unit":"requests","per":null,"currency":null,"usd":null,"fx_date":null,"parse":"ok"},{"path":"$.limits[0].value","kind":"limit:retention-clamped","num":null,"unit":null,"per":null,"currency":null,"usd":null,"fx_date":null,"parse":"unparsed"}],"unknown":[["$.egress.metered","egress-unknown"],["$.egress.terms","not-stated"],["$.per_object_cap.notes","process"],["$.per_object_cap.stated","not-applicable"],["$.reliability_note","none-observed"],["$.retention.notes","process"],["$.tooling","not-stated"]],"history":[],"drift":[]},{"rid":"inference/cerebras","card":{"rid":"inference/cerebras","eid":"cerebras","topic":"inference","slug":"cerebras","provider":"Cerebras","url":"https://inference-docs.cerebras.ai/support/rate-limits","domain":"cerebras.ai","category":"inference endpoint, keyed free trial","tier":null,"verdict":"trial-only","vorder":2,"grp":"trial","self_hosted":0,"confidence":"documented","binding":"retention-clamped","identity_kind":"card","identity_basis":"stated","needs_card":1,"needs_phone":0,"needs_id":0,"needs_institution":0,"country":null,"crypto":null,"interfaces":"rest","egress_metered":null,"per_object_bytes":null,"retention_days":30,"verified_at":"2026-10-28T09:47:54.945Z","verified_basis":"live","checked_on":"2026-10-28","stale_on":"2026-11-28","n_evidence":7,"usd_month":null,"usd_per_tb_month":null,"summary":"a Free Trial, not a free tier: USD 5 of credits granted after a verified payment method is added, expiring 30 days after they are granted.
