• Apple launched latest developer betas last week with generative AI features announced at WWDC, coming to iPhones, iPads, and Macs in months.
• On Macs, can read instructions programmed into model supporting Apple Intelligence features, shown as prompts before chatting.
• A macOS 15.1 beta subreddit member discovered files with backend prompts. Can't alter files but they hint at how it works.
• Examples include prompts for a "helpful mail assistant," Apple's "Rewrite" feature, summarizing emails, and generating a "Memories" video.
• Some prompts have specific rules like limiting answers to 50 words, not hallucinating, etc.
• Files refer to the model as "ajax" (rumored internal name last year).
• Person who found instructions also posted how to locate files within macOS Sequoia 15.1 developer beta (expand "purpose_auto" folder, etc.). Be cautious as these files contain sensitive system info.
