Google replaces Assistant with Gemini across devices

In early 2025, Google made significant advancements in its AI technology by deploying Gemini, as reported by users in the Google Home Public Preview program. This update, which impacted Nest smart speakers, featured a striking visual change where the familiar four-light animation transitioned from white to the signature blue and purple hues of Gemini. To access the new features, users must have the 'Experimental AI features' enabled and be using devices equipped with the specific Cast firmware, version 3.75.468348. Notably, the Nest Mini 2nd generation has not yet received this update, although it is included in the preview program. The company also indicated that they are in the testing phase of a Gemini-powered Google TV experience, signaling a broader rollout of the Gemini technology. Last year, Google announced its intentions to transition from the older Google Assistant to newer Gemini models, although the Assistant name was still retained for smart home products. However, during March 2025, Google confirmed its plan to entirely phase out the Assistant in favor of Gemini. This development has raised questions about the future of voice assistants in general, especially as millions of users have already adapted to the Gemini interface on their Android devices. The initiative aligns with a strategic vision where AI becomes central to Google's ecosystem, providing a unified user experience across multiple device types, including tablets, cars, headphones, smartwatches, speakers, smart displays, and TVs. As major technology companies continue to enhance their AI capabilities, the competition in the smart home sector intensifies. With Apple's revamped Siri expected later in the year and Amazon's AI-enhanced Alexa already available, consumers can anticipate a profound shift in how they interact with their smart home devices. The introduction of Gemini represents a pivotal moment for Google as the company seeks to redefine user engagement through advanced AI technologies. Given these competitive dynamics and user reactions, the tech industry is eager to observe how Google manages its transition to Gemini and what this means for the smart home landscape moving forward. The changes not only reflect advancements in AI but also showcase the potential limitations of the existing smart assistant models. As more users embrace Gemini, they may discover new functionalities that fundamentally change their relationship with technology.
