# Apple Seeds Fourth visionOS 27 Beta to Developers

Apple today provided developers with the fourth beta of an upcoming visionOS 27 update for testing purposes, with the beta coming two weeks after Apple released the third beta.

visionOS 27 can be installed by opening the Settings app, going to Software Updates, and opting into Beta Updates.

visionOS 27 introduces Siri AI, the smarter and more capable version of ‌Siri‌ that's similar in capability to chatbots like ChatGPT and Claude. On the Vision Pro, ‌Siri‌ can answer questions about anything the wearer is looking at, and there's a new ‌Siri‌ orb that can be placed anywhere in wearer's virtual space.

Panorama photos can be turned into spatial environments, and there's a new Icelandic Thórsmörk environment that features dramatic mountains, valleys, and glaciers, along with the northern lights. Web Environment support allows developers to create 360-degree environments in Safari for a more native Vision Pro browsing experience.

App windows are now curved to provide a more immersive workspace, and Control Center has been reorganized to make system controls easier to find. Apple added a smaller widget size, and notifications automatically expand when the wearer looks at them.
