Cerebras: data residency & retention
Headquarters
🇺🇸 United States (US)
Where inference runs
US
Cerebras discloses US inference datacenters (Santa Clara, Stockton, Dallas, Minneapolis, Oklahoma City) and markets inference as running entirely on US-based infrastructure; first European capacity is promised by end of 2026, not live today.
Region pinning
Enterprise plans only
The self-serve API has a single endpoint with no region selection; in-region residency claims apply to enterprise dedicated and on-prem deployments only.
Prompt retention
Not retained
Privacy policy states inputs and outputs for inference services are not retained ('never stored, logged, or reused'); no abuse-log carve-out or retention window is disclosed.
Trains on API data
No
Terms state the content license does not grant Cerebras the right to use service content for training or fine-tuning models.
Zero data retention
Available
Zero data retention is the stated platform default, not a separate toggle or paid tier.
