May 18, 2025 — Google has taken a quiet but notable step in its transition from Google Assistant to Gemini, as Nest Audio speakers enrolled in the Google Home Public Preview have begun displaying Gemini’s blue and purple light indicators — signaling a deeper integration of its next-generation AI model into smart home devices.

💡 Gemini Visuals Now on Nest Audio
Users who have enabled “Experimental AI features” on their Nest Audio speakers are seeing a new four-light animation in Gemini’s signature gradient when issuing voice commands or receiving responses. This aesthetic change is being rolled out to devices running Cast firmware version 3.75.468348.
These visual changes align with previous Gemini-themed updates already present in Android and Google TV ecosystems. The rollout currently appears limited to Nest Audio, with no confirmed sightings on the 2nd-gen Nest Mini, likely due to hardware constraints.
🧠 What’s Changing Behind the Scenes?
Since late 2023, Google has been gradually testing Gemini-powered upgrades to Google Assistant, aiming to bring more fluid, conversational, and AI-driven responses across its ecosystem. The latest update includes enhanced voices and smarter context handling, as part of the broader transition to Gemini AI.
Despite these enhancements, Google has not officially renamed the Assistant on smart speakers, but that may be changing soon.
🏷️ Branding in Flux: Google Assistant or Gemini?
The shift to Gemini branding raises important questions about product identity. While the Assistant label remains familiar to millions of users, especially on smart speakers and displays, Google has increasingly positioned Gemini as the unified AI brand across mobile, TV, and now, possibly, smart home products.
-
At CES 2025, Google confirmed Gemini would power Assistant on Android and Google TV.
-
This week, the company began referring to the AI experience as “Gemini on Google TV.”
Given this momentum, a full branding transition to “Gemini on Nest” devices appears imminent — a move that would help Google align its AI presence under a single, cohesive brand.
📱 What to Expect Next
With Gemini now influencing everything from phones and TVs to smart speakers, it’s clear that Google is working toward a unified AI experience across its hardware. Whether it’s renamed or not, Nest Audio’s visual update suggests that Gemini is no longer just behind the scenes — it’s front and center.
