What happens to your prompts?
PrivateReviewed
Cerebras states inference inputs and outputs are not retained or used for content-based training or improvement.
- Plan Scope
- Cerebras Cloud inference, training, and chatbot services under its public terms and Cloud privacy policy.
- Prompt Retention
- Cerebras states it does not retain inputs and outputs associated with inference, training, or chatbot services.
- Response Retention
- Same non-retention statement as prompts.
- Ordinary Logging
- Service logs are retained only while necessary to provide the services; account and personal data follow purpose-based retention plus legal, dispute, and enforcement exceptions.
- Model Training
- No ordinary retained inputs or outputs are available for model training, and no inference-content training right is disclosed in the reviewed documents.
- Product Improvement
- Non-content service data and user feedback may support operations and improvement; the privacy policy does not authorize using inference payloads for improvement.
- Human Or Operator Access
- The non-retention policy limits stored access, but transient processing, security operations, and legal obligations remain; no separate zero-operator-access promise is published.
- Subprocessors And Routing
- Cerebras and its service providers process data under the privacy policy; public documentation does not describe inference as a gateway to changing external model providers.
- Deletion Controls
- Inference content is not retained. Other personal data can be subject to privacy-right requests and is deleted or aggregated when no longer necessary, subject to legal exceptions.
- Caveat
- The policy gives no precise maximum for service logs and does not call the design zero operator access. Non-retention of payloads is a first-party policy statement.
