+These models are hosted on xAI. xAI operates {% data variables.copilot.copilot_grok_45 %} in {% data variables.product.prodname_copilot %} under a zero data retention API policy. This means xAI commits that user content (both inputs sent to the model and outputs generated by the model):

+Will **not** be:
+* Logged for any purpose, including human review
+* Saved to disk or retained in any form, including as metadata
+* Accessible by xAI personnel
+* Used for model training

+Will **only**:
+* Exist temporarily in RAM for the minimum time required to process and respond to each request
+* Be immediately deleted from memory once the response is delivered
