Apple's iOS 18 AI features might work completely offline
Apple is reportedly planning to run its initial batch of iOS 18 AI features entirely on-device without cloud servers. Basic capabilities like smart text generation in Messages, Safari, and Siri will work offline to ensure privacy, while heavier tools may tap cloud partners. Apple is expected to detail the plans at WWDC on June 10.
Every tech giant is rushing to plug their AI into massive server farms, but Apple is taking a noticeably different route for its first big move.
According to Bloomberg's Mark Gurman, the initial wave of AI features coming in iOS 18 will run entirely on-device, functioning without any cloud processing or internet connection at all. AppleInsider has since confirmed the reporting with its own sources.
Offline smarts powered by Ajax
Under the hood, Apple is relying on an in-house large language model known internally as "Ajax."
While high-end tasks will eventually need a data connection, basic text analysis and offline response generation will happen locally. Apple has reportedly been testing on-device text generation for quite a while, aiming to upgrade staple apps like Messages, Safari, Spotlight Search, and Siri.
For heavy lifting, Apple reportedly held talks with Google and OpenAI to license their cloud-based models rather than deploying its own online LLM right away. Apple is set to unveil its complete AI strategy at WWDC, kicking off on June 10.
Why it matters
We think launching with on-device AI first is a classic Apple play, though partly born out of necessity.
For everyday iPhone users, local execution means blazing speed, offline reliability, and rock-solid privacy. Having your phone summarize notes or draft quick replies without shipping personal data to a remote data center is a massive trust win. The obvious tradeoff is capability: a mobile chip simply cannot match frontier cloud models, so expectations around complex reasoning need to stay grounded.
Strategically, outsourcing cloud infrastructure to Google or OpenAI shows Apple knows its limits. Instead of rushing an unpolished cloud LLM that hallucinates, Apple protects its brand while leaning on proven market leaders.
The friction will be transparency. Apple will have to draw a clear, understandable line for users between what stays private on their phone and what gets sent off to partner servers.
