Before iOS 18 fully delivers its promised Apple Intelligence features, rumors about iOS 19 are already making waves. The upcoming update is expected to introduce LLM Siri, a smarter and more conversational version of the assistant. However, users will need to wait until spring 2026 to experience it. According to Bloomberg’s Mark Gurman, many of iOS 19’s Apple Intelligence updates have been delayed. The new Siri, along with other postponed features, is likely to debut during WWDC 2025.
LLM Siri: Smarter and More Conversational
Apple is reportedly working on an advanced Siri version named LLM Siri, designed to rival intelligent chatbots like ChatGPT. This version will leverage large language models to deliver a more natural, human-like interaction. Unlike the current Siri, which struggles with complex tasks, LLM Siri will handle advanced requests seamlessly.
The updated Siri aims to engage in continuous conversations, offering smarter and more dynamic responses. These improvements will make Siri a reliable alternative to external services like ChatGPT and Gemini, which iOS 18 integrates.
As per reports, it will be part of the iOS 19.4 update, marking a significant leap forward in Apple’s AI capabilities.
Delays in iOS 19 Features
Mark Gurman revealed that many planned features for iOS 19 have been delayed until spring 2026. Beyond Siri, details about other postponed functionalities remain unclear.
In the meantime, iOS 18.2, set to release in December, will add ChatGPT integration to Siri. A future iOS 18.4 update will further enhance Siri with on-screen awareness and per-app controls. However, it will still lack the conversational sophistication expected from LLM Siri.
Once LLM Siri arrives, iPhone users will likely depend less on third-party services for advanced AI interactions. By harnessing large language models, Apple intends to elevate Siri to a leading position among virtual assistants.
Though users must wait over a year for these changes, the anticipation surrounding iOS 19’s LLM Siri reflects Apple’s ambition to redefine the role of AI in its ecosystem.
