"Hey Plex" is ready to launch on the Galaxy S26, Samsung builds a multi-AI ecosystem at the system level

JAKARTA - Samsung is accelerating its ambitions in the field of mobile artificial intelligence with a bolder approach. For the Samsung Galaxy S26 line that will soon be launched, the South Korean company announced an in-depth integration with Perplexity AI's search-based AI engine. This integration comes in the form of a new agent with a special wake phrase: "Hey Plex".

This move marks a new phase of Galaxy AI. Over the past few years, Samsung has worked closely with Google to gain early access to the Gemini model and related features. However, the company now seems to want to reduce its dependence on a single AI ecosystem. Instead of replacing Gemini or Bixby, Samsung chose a multi-agent approach.

This means that more than one AI assistant will live in one device. In addition to the latest versions of Gemini and Bixby, Perplexity now has a direct path to the operating system. According to Samsung, this strategy is not a speculative experiment. Based on the company's internal research, almost 80 percent of users currently rely on at least two different AI tools in their daily lives. One for research, another for scheduling or communication.

Instead of forcing users to "choose a camp", Samsung wants the device to determine the best agent according to the context. With integration at the framework level, the Galaxy S26, Samsung Galaxy S26+ and Samsung Galaxy S26 Ultra are able to understand cross-application contexts such as Gallery and Calendar without manual copying and pasting. In practice, this means that users can research vacation destinations, then automatically make notes, set flight reminders, and add schedules to the calendar in one seamless flow.

"Hey Plex" is not positioned as just a question-and-answer machine. Because it is embedded directly in the system, this agent is designed to handle multi-step workflows. This is important. Many previous voice assistants stopped at the level of a single command. With deeper integration, Perplexity can act as a task orchestrator, not just a question responder.

Strategically, this approach is interesting. The consumer AI industry is moving from a "one assistant for all" model to specialization. Some models excel at reasoning, others at text generation, some at ecosystem integration. Samsung seems to be reading that trend and choosing to build orchestration, not single dominance.

However, the multi-agent approach also presents technical challenges. Inter-model coordination requires precise context management, especially to maintain data consistency and user privacy. If the implementation is mature, the Galaxy S26 has the potential to be a device that is not only smart, but also adaptive to the way users work.

Samsung also signaled that Plex integration may not be exclusive for long in the flagship line. Details of other devices that will get support are said to be announced soon, opening up opportunities for owners of previous generations of Galaxy.

In the midst of increasingly dense mobile AI competition, Samsung seems to want to turn mobile phones from just an endpoint into a coordination center for digital intelligence. If Gemini is an analytical brain and Bixby is the guardian of the Samsung ecosystem, then Plex is projected as a real-time information navigator.

One device, three agents, and one user in control. In an era where attention is currency, Samsung is trying to ensure AI works behind the scenes, not vying for the stage.
