Developers on the App Store Small Business Program* can now get access to a server-based Large Language Model (LLM) via Private Cloud Compute (PCC) at Apple with no cloud API cost (subject to usage limits).
Based on the capabilities required for their specific use cases, developers on Apple platforms can choose whether to use Apple’s local (on-device) model, or Apple’s server model (via PCC).
Apple highlight that PCC: i) does not store data, ii) only uses data to process requests, iii) has been independently verified by researchers.
Both the local (on-device) model and the server model (via PCC) provide developers with some assurance over the flows of (potentially personal) data that arise from interaction with an LLM.
Worth noting that data flows arising from interaction with an LLM (eg. prompts and responses) are likely to represent only a subset of the flows into, and out of an application.
Developers need to understand how these data flows integrate with other flows in an application to ensure that personal data is processed in line with expectations.
*Additionally, app must have less than 2 million total first-time app store downloads
