What happens to your prompts?

Partially privatePartial review

Default retention and training treatment are not clear; stronger traceless operation requires explicit configuration.

Plan Scope: AI21 Studio and Models API; negotiated Traceless Operations has stronger handling than default access.
Prompt Retention: The model terms say the service is not intended as storage, but no default public retention maximum was verified. Traceless Operations can disable content retention when explicitly configured.
Response Retention: Same unresolved default; Traceless Operations applies only when contracted/configured.
Ordinary Logging: Usage and operational metadata may be retained; the public terms do not publish a complete default content-log TTL.
Model Training: No sufficiently clear plan-specific default training statement was found in the reviewed public model terms.
Product Improvement: The agreement permits service operation and improvement uses subject to customer terms; exact content scope remains unclear.
Human Or Operator Access: Support, security, and legal workflows may permit access; Traceless Operations is the documented stronger control.
Subprocessors And Routing: AI21 and its cloud/service subprocessors process requests.
Deletion Controls: Traceless Operations supports a retain=false mode; default account deletion does not establish immediate request-content deletion.
Caveat: Do not infer Traceless Operations for free Studio access; it is a separately described negotiated/configured mode.
