Apple has released the first public betas for iOS 27 and iPadOS 27, enabling users with compatible devices to test the latest software. To participate, users can sign up on Apple's beta website and opt-in via their device's settings.

This public beta mirrors the third developer beta and introduces Siri AI, a significantly enhanced version of Siri capable of web searches, accessing personal information, and performing actions across apps. This new Siri functions more like conversational AI models and requires devices supporting Apple Intelligence.

Key updates include refinements to the Liquid Glass design, new AI features integrated into apps like Camera (Visual Intelligence for meal nutrition and bill splitting) and Photos (AI editing tools), and Safari's automatic tab organization. Users can also create Shortcuts and Safari extensions using natural language. Performance improvements across the system are also noted, making the user experience faster on various iPhones.
