Apple has been actively working to improve its lackluster virtual assistant. While a future iOS 18 the update allows Siri to understand the contents of the screen, the service still lags behind competitors such as Gemini and ChatGPT. Fortunately, the iPhone maker was able to load Siri with more advanced large language models (LLM) through an iOS 19 update — but you’ll have to wait.

According to BloombergApple is internally developing an “LLM Siri,” which could debut for iOS 19 users around spring 2026. The company could potentially announce the project during the upcoming WWDC, likely in June 2025.

While iOS 18 is being integrated ChatGPT into the system, Siri continues to underperform when used independently. By relying on more advanced LLMs to power the assistant, Siri on iOS 19 may finally gain human conversational capabilities. The upgrade would also make Apple less dependent on third parties, such as OpenAI.

In addition to becoming more conversational, the rumored Siri will likely support iOS 18’s App Intents feature. This would enable it to perform complex tasks in first- and third-party apps using natural language. It can also be integrated into other Apple Intelligence features, such as writing tools for text generation and manipulation.

The report shows that Apple is currently testing “LLM Siri” as a dedicated app. However, when it rolls out to iOS 19 and macOS 16 users, it will likely be built into the existing Siri experience. This suggests that users will still not be able to review or interact with their query history beyond the existing methods.
