The page All OpenAI terms

Added: By default, abuse monitoring logs are retained for up to 30 days. Eligible customers can use Zero Data Retention, subject to the limitations below.
Added: Prompt caching may store encrypted key/value tensors in GPU-local storage as application state. This data is stored on the local GPU machines and is not retained after the 24-hour expiration. To learn more, see the prompt caching guide .
Added: See image and file inputs for the CSAM retention exception for image inputs.
Added: The Decisions API is eligible for HIPAA use under an executed OpenAI Business Associate and Healthcare Addendum, subject to the applicable account configuration requirements.
Added: Images and files may be uploaded as inputs to /v1/responses (including when using the Computer Use tool), /v1/chat/completions , and /v1/images . Images may also be uploaded to /v1/decisions . Image and file inputs are scanned for CSAM content upon submission. If the classifier detects potential CSAM content, the image will be retained for manual review, even if Zero Data Retention, Modified Abuse Monitoring, or Private Retention with PSP is enabled.
Removed: Images and files may be uploaded as inputs to /v1/responses (including when using the Computer Use tool), /v1/chat/completions , and /v1/images . Image and file inputs are scanned for CSAM content upon submission. If the classifier detects potential CSAM content, the image will be retained for manual review, even if Zero Data Retention, Modified Abuse Monitoring, or Private Retention with PSP is enabled.
Added: Fast mode supports EU data residency for GPT-6.1 Sol, GPT-6 Sol, and GPT-6 Luna. Fast mode is not available with EU data residency for GPT-6 Astra. GPT-6.1 Sol, GPT-6 Sol, and GPT-6 Luna support EU data residency with Standard, Flex, and Batch processing. Ultrafast mode for GPT-6.1 Sol supports US and EU data residency and global processing. GPT-6 Astra Ultrafast supports US data residency and global processing only.
Removed: Fast mode is not available with EU data residency for GPT-6 Astra, GPT-6.1 Sol, GPT-6 Sol, or GPT-6 Luna. GPT-6.1 Sol, GPT-6 Sol, and GPT-6 Luna support EU data residency with Standard, Flex, and Batch processing. Ultrafast mode supports US data residency and global processing only. It does not support EU or other non-US regional processing endpoints.
Added: Fast mode supports EU data residency for GPT-6.1 Sol, GPT-6 Sol, and GPT-6 Luna. Fast mode is not available with EU data residency for GPT-6 Astra. GPT-6.1 Sol supports only US and EU data residency.
Added: Available in all supported API regions. Regional processing is supported in the United States and Europe (EEA + Switzerland). Prompt caching is subject to the retention limitations below.
Removed: Fast mode is not available with EU data residency for GPT-6 Astra, GPT-6.1 Sol, GPT-6 Sol, or GPT-6 Luna. GPT-6.1 Sol supports only US and EU data residency.
Added: The Decisions API is available in all supported API regions. Regional processing is supported in the United States and Europe (EEA + Switzerland). Availability in a region does not imply that inference is performed in that region.
