Ahead of Wednesday Samsung Unpacked event in San Francisco (we’ll be there!), Samsung signaled a strategic shift that more important than any single model benchmark: Galaxy AI is evolving into a multi-agent layer where users can choose between integrated assistants or specialists, starting with Perplexity on upcoming flagship Galaxy phones.
On paper, the announcement is about “more choice and flexibility.” In practice, Samsung is positioning itself to own the interface layer that sits above the LLMs. Galaxy AI is positioned as the orchestrator that can hand off tasks across agents and apps, without forcing users to manually jump between separate AI experiences.
Samsung says Perplexity will be callable via a dedicated wake phrase (“Hey Plex”) or quick-access controls like press-and-hold on the side button, and it will be embedded across Samsung Notes, Clock, Gallery, Reminder, and Calendar (plus “select third-party apps”).
This matches what we’ observed in the broader market: AI is going agentic, fast. The differentiator is no longer “who has the best model this quarter,” because leadership keeps leapfrogging.
The durable advantage shifts to whoever owns the control plane: permissions, context routing, cross-app actions, and the default UI users touch all day. Samsung has distribution, default placement, and deep OS hooks. That is a very different moat than trying to build a frontier model.
If Samsung can hide the complexity behind intent routing and consistent UX, then multiple agents becomes a backend detail. That said, Samsung is adding one visible layer of complexity: another wake phrase and another branded assistant users must learn (“Hey Plex”).
The prominence of “Hey Plex” and the depth of app integration seems more than a casual plug-in. There has been prior reporting that Samsung was exploring a broader Perplexity relationship, potentially including investment and deeper product placement. Nothing in Samsung’s announcement confirms commercial terms, but the incentives are there.
If Samsung executes, it does not need to pick the ultimate LLM winner. It just needs Galaxy AI to become the default way Galaxy users get things done.
