Apple is working on an all-new “LLM Siri” architecture for its digital assistant that could launch as soon as spring 2026 in a future iOS 19 update, reports Bloomberg‘s Mark Gurman in a new report.
The new Siri will be powered by Apple’s advanced Large Language Models (LLM), which will make the digital assistant more conversational and ChatGPT-like. The project is referred to within Apple as “LLM Siri,” and will allow the assistant to tackle more complex questions quicker than possible today. LLM Siri will make the digital assistant sound more natural and human-like, rivaling similar chatbot rivals today.
The report adds that LLM Siri should integrate better with other Apple Intelligence features, something that’s not possible today. For example, users will be able to ask Siri to use Writing Tools to summarize pieces of text on the screen or rewrite text to change its tone.

The new Siri prototype is currently being tested as a separate app on iPhone, iPad, and Mac devices by Apple engineers. However, the company plans to integrate the new infrastructure backend into the usual Siri interface when it launches. Currently, internal plans call for the LLM Siri to be announced next year, likely as part of WWDC 2025 and iOS 19. However, it won’t actually launch to consumers until 2026 as a future iOS 19 update.
LLM Siri’s rollout should be similar to that of Apple Intelligence, where the company previewed many features in WWDC 2024 in June that won’t launch until December and into 2025. Apple previewed a new Siri experience with precise in-app controls and onscreen awareness. However, it won’t be ready until iOS 18.4 next spring.
