Apple is inviting investigations into the Private Cloud Compute (PCC) system that powers more computationally intensive Apple Intelligence requests. The company is also expanding its bug bounty program to offer payouts of up to $1,000,000 for people who discover PCC vulnerabilities.
Apple Intelligence bug bounty invites researchers to test its privacy claims
Researchers can run a security analysis of Private Cloud Compute in a virtual machine and evaluate some of the system’s source code on GitHub.

The company has boasted about how many AI features (branded as Apple Intelligence) will run on-device without leaving your Mac, iPhone, or other Apple hardware. Still, for more difficult requests, it will send them to PCC servers that are built using Apple Silicon and a new operating system.
Many AI applications from other companies also rely on servers to complete more difficult requests. Still, users don’t have much line of sight into how secure those server-based operations are. Apple, of course, has made a big deal over the years about how much it cares about user privacy, so poorly designed cloud servers for AI could poke a hole in that image. To prevent that, Apple said it designed the PCC so that the company’s security and privacy guarantees are enforceable and that security researchers can independently verify those guarantees.
For researchers, Apple is offering:
- A security guide that spells out the technical details of the PCC
- A “Virtual Research Environment” that lets you do a security analysis of PCC on your Mac (though you’ll need to have a Mac with Apple Silicon and 16GB more of memory and be running the latest macOS Sequoia 15.1 Developer Preview)
- Source code on GitHub for “certain key components of PCC that help to implement its security and privacy requirements”
With the bug bounty, Apple is offering payouts from $50,000 to $1,000,000 for vulnerabilities discovered across a few different categories. Apple also will evaluate any security issue for a potential reward that “has a significant impact to PCC.”
The first Apple Intelligence features are set to launch for everyone with iOS 18.1, which is expected next week. Some of the bigger Apple Intelligence features, including Genmoji and ChatGPT integration, appeared in the first iOS 18.2 developer beta released yesterday.
