The docs disagree
Training on API data
Moonshot's OpenPlatform terms say Customer Content may be used to improve the Services unless agreed otherwise in writing, and point to enterprise arrangements for training restrictions. The Kimi help center says API data is not used to train or improve Kimi models. The help page is served for the China locale and its examples use api.moonshot.cn, so it may describe the China platform.
“We may use Content to provide, maintain, develop, support, and improve the Services, comply with applicable law, enforce our terms and policies, and keep the Services safe and secure. Customer who requires restrictions on the use of Customer Content for training or improving Moonshot AI models may contact Moonshot AI to discuss available enterprise arrangements or separate written agreements. Unless otherwise expressly agreed in writing, Customer Content may be used for the foregoing purposes.”
“No. User data submitted via the API, including input content and model outputs, will not be used to train or improve Kimi models.”
How long are prompts kept by default?
- Default retention
While the account is active
No fixed duration. Input is retained while the account is active; retention can depend on settings.
“For example, account, input, and payment information are retained while your account is active. Violation-related information is retained until the violation is resolved. Also, in some cases, the length of time we retain data depends on your settings.”

Does it train on your API data?
The docs disagree
Terms: content may be used unless agreed in writing. Help center: not used for training
Contradictory. OpenPlatform Terms (Last Updated July 30th, 2026): Content may be used to improve the Services, and restricting training use needs an enterprise arrangement or written agreement. Kimi Help Center API page: API data is not used for training.
“We may use Content to provide, maintain, develop, support, and improve the Services, comply with applicable law, enforce our terms and policies, and keep the Services safe and secure. Customer who requires restrictions on the use of Customer Content for training or improving Moonshot AI models may contact Moonshot AI to discuss available enterprise arrangements or separate written agreements. Unless otherwise expressly agreed in writing, Customer Content may be used for the foregoing purposes.”
“No. User data submitted via the API, including input content and model outputs, will not be used to train or improve Kimi models.”

Research notes
- The Kimi Help Center API data page is served with language 'en-cn' and its file-deletion example uses api.moonshot.cn, so it may describe the China platform rather than the Singapore OpenPlatform. The help page says the platform 'has obtained relevant security and compliance certifications' without naming them.
