It’s been reported that although Apple will unveil a more conversational Siri with iOS 19 at WWDC 2025, many other planned features, including this upgrade, will actually be delayed until iOS 19.4 launches in spring 2026.
Various reports indicate that Apple’s improved “LLM Siri,” designed to rival AI chatbots like ChatGPT and Gemini, aims to handle complex requests and enable natural interactions. However, despite its unveiling at WWDC 2025, it is not expected to launch publicly until iOS 19.4 in spring 2026.
In the meantime, incremental updates will enhance Siri’s capabilities. iOS 18.2, arriving in December 2024, will integrate ChatGPT into Siri for improved responses. Later updates, such as iOS 18.4, will add on-screen awareness and per-app controls, although full conversational features will not appear until the LLM Siri release in 2026.
The delays highlight Apple’s cautious approach to deploying advanced AI, ensuring thorough testing and alignment with its privacy and security standards. This measured strategy aims to deliver a refined and reliable experience to users.
For businesses, the upgraded Siri promises improved customer service, streamlined workflows, and better accessibility. However, they will need to wait until 2026 to fully utilise these advancements while leveraging interim improvements from upcoming iOS 18 updates.
While Apple’s plans for a more advanced Siri are promising, the extended timeline highlights the need for businesses to adapt gradually. Monitoring updates in iOS 18 and preparing for iOS 19.4’s features will ensure readiness to integrate the new Siri into operations effectively.
