The effect of Google’s Gemini, Microsoft Copilot, and OpenAI’s ChatGPT has been greater than that of Apple’s AI initiatives. Apple Intelligence, the company’s AI stack, hasn’t improved functionality for Mac and iPhone consumers and has even led to an internal management crisis.

User data seems to have the potential to save the sinking ship. In a Machine Learning research paper released earlier today, the business describes a novel method for training its onboard AI using information saved on your iPhone, beginning with emails. These emails will be utilized to enhance features like writing tools and email summaries.

An overview of AI training in short

Here is a quick overview of how AI technologies operate before we go into the details. Training is the first stage, which basically entails feeding a “artificial brain” a large volume of data generated by humans. Consider research papers, books, essays, and more. Its replies improve with the amount of data it receives.
This is due to the fact that chatbots, which are officially referred to as Large Language Models (LLMs), attempt to comprehend word relationships and patterns. In essence, tools like ChatGPT—which is now a part of Apple Intelligence and Siri—are word predictors.
However, the amount of data available to train an AI is limited, and the whole process is costly and time-consuming. So why not train your AI with data created by AI? According to studies, it will, in theory, “poison” the AI models. This entails more erroneous answers, babbling, and producing deceptive results.

How is Apple planning to fix its AI?

By improving and fine-tuning an AI tool, one may enhance its reactions rather than depending just on artificial data. However, providing an AI assistant with more human data is the most effective way to train it. The best place to get such information is on your phone, but a business can’t just do that.

It would be a clear invitation to litigation and a grave invasion of privacy.

Without ever copying or forwarding your emails to its servers, Apple plans to snoop around in them. To put it simply, all of your data is still stored on your phone. Furthermore, technically, Apple won’t “read” your emails. Rather, it will only contrast them with a collection of phony emails.

Finding the synthetic data that most closely resembles a human-written email is the key to this process. That would allow Apple to determine what kind of data is most representative of how people really converse. According to Bloomberg, Apple has “typically” used fake data for AI training so far.

“We can then use this synthetic data to test the quality of our models on more representative data and find areas where features like summarization need to be improved,” the business says. It could eventually result in noticeable enhancements to the replies you get from Apple Intelligence and Siri.
Apple wants to enhance its email summarizing system and a few things in the Writing Tools set based on lessons learned from real-world human data. The business guarantees that “the contents of the sampled emails never leave the device and are never shared with Apple.” Apple claims to have implemented comparable privacy-first training techniques for the Genmoji system previously.

Why is this a significant advancement?

At the moment, the summaries that Apple Intelligence provides in Mail may sometimes be very unclear and, on occasion, completely nonsensical. The current state of app notifications is no different, and after receiving criticism from the BBC for falsifying news reports, Apple was forced to temporarily halt it. In our team discussions, the summary notifications have become a joke because of how horrible things are. When attempting to describe emails or chats, Apple Intelligence often groups together arbitrary statements that either don’t make sense or present the situation completely differently. The main issue is that AI currently has trouble understanding human purpose and context. Training it on more situation-aware content with appropriate contextual knowledge is the best method to correct it. Though they haven’t exactly been a panacea, AI models that can reason have recently entered the market.
Apple’s approach seems to combine the finest features of both approaches. The business claims that by improving the language and subjects of its fictitious emails, it is able to train its models to provide better text outputs for features like email summaries while maintaining anonymity.

The good part comes after. Not every email saved on Macs and iPhones worldwide will be reviewed by Apple. Rather, it is adopting an opt-in strategy. The AI training process will only include customers who have specifically consented to provide Apple access to their Device Analytics data.

It may be enabled by doing the following steps: Settings > Security & Privacy > Analytics & Enhancements. According to reports, the business will implement the plans with the next beta versions of macOS 15.5 and iOS 18.5, as well as iPad 18.5. There is already a matching build available for developers.
