xAI appears to be preparing the launch of Grok 3.5, with a rollout anticipated later this week. Alongside the core update, voice mode is being revamped with several UI-level changes already spotted in the latest iOS build. A new settings toggle now lets users auto-launch voice mode when opening the app, hinting at deeper integration of voice-first interactions.

It also comes with an option to launch an app directly in voice mode and a new SuperGrok upsell.

The UI has shifted significantly: a redesigned toggle now sits at the top to switch between chat and voice modes, while voice-specific controls—including personality selection, speed, and voice type—have been consolidated into a bottom slider that expands with additional options. This design seems optimized for larger devices, reducing the need for hand movement across the screen.

One of the more intriguing changes affects the camera view. It now opens with a fully transparent overlay interface, giving the impression of mixed-reality capabilities. While no functionality around real-world interaction has been confirmed, this visual shift could signal xAI’s ambitions toward spatial or AR-style computing. These updates, however, remain gated behind feature flags for now.
Meanwhile, on Grok for Android, a separate update hints at personality support for voice mode as well, although the functionality has not been activated yet. This cross-platform effort suggests a unified vision for voice-driven experiences in Grok, aligning with Elon Musk’s broader ambitions for AI-first platforms. Grok 3.5 might serve as a critical step toward those goals, with this week likely revealing how far xAI is willing to go in that direction.
