Samsung Galaxy AI Goes Multi-Agent: Perplexity Joins Bixby and Gemini
Samsung announced a major expansion of Galaxy AI on February 23, 2026, turning upcoming Galaxy S26 devices into true multi-agent orchestrators — with Perplexity AI joining Bixby and Gemini at the system level.
Samsung Galaxy AI Goes Multi-Agent: Perplexity Joins Bixby and Gemini
On February 23, 2026, Samsung announced a significant expansion of its Galaxy AI platform. Upcoming Galaxy devices — most notably the Galaxy S26 — will ship with not one, not two, but three AI agents built into the operating system at the system level: Bixby, Gemini, and now Perplexity.
It's a quiet but important signal about where mobile AI is heading.
The "Hey Plex" Moment
The headline feature is the addition of Perplexity AI as a dedicated voice agent. Users will be able to invoke it with the wake phrase "Hey Plex" — alongside the existing "Hey Bixby" and Google Assistant/Gemini — or by pressing and holding the side button.
But the integration goes much deeper than a voice shortcut. Perplexity is embedded at the framework level across Samsung's own apps: Notes, Clock, Gallery, Reminder, and Calendar, as well as select third-party apps. This means Perplexity can participate in multi-step workflows without the user manually switching apps or repeating context.
Galaxy AI as an Orchestrator
Samsung frames Galaxy AI not as a single assistant but as an orchestration layer. The device decides context; the user chooses the agent. Won-Joon Choi, Samsung's COO for the Mobile eXperience division, put it clearly:
"Galaxy AI acts as an orchestrator, bringing together different forms of AI into a single, natural, cohesive experience."
This framing matters. It aligns exactly with what the broader AI industry has been building toward with protocols like MCP and A2A — the idea that specialized agents should be able to coexist and hand tasks between each other, rather than one monolithic assistant trying to do everything.
On a phone, that looks like: Gemini handles general knowledge and Google-ecosystem tasks, Bixby handles device controls and Samsung services, and Perplexity handles search-oriented, citation-backed queries — all without the user having to manage which agent to use manually.
The Stat That Explains Everything
Samsung cited internal research showing that nearly 8 in 10 users now rely on more than two types of AI agents in their daily routines. Whether you take that exact number at face value or not, the trend it reflects is real: people aren't loyal to a single AI. They use Claude for writing, Perplexity for research, ChatGPT for coding questions, and Gemini for Google-integrated tasks.
The phone is simply catching up to user behavior.
Why This Is More Than a Partnership Announcement
Previous Samsung AI partnerships (like the Gemini deal with Google) were about replacing Bixby as the primary assistant. This expansion takes a different approach: coexistence. Each agent occupies a defined niche, and users can set their preferred defaults.
This is a model that avoids the zero-sum fight over which AI "wins" on the device. Instead, it acknowledges that users want different agents for different jobs — and the operating system should support that rather than force a single choice.
For Perplexity specifically, this is a significant distribution play. Being baked into the side button of Galaxy devices puts it in the hands of millions of users who may never have sought it out on their own.
What to Watch
Samsung hasn't announced which specific Galaxy devices will support the multi-agent features or exactly when Perplexity's integration goes live. Additional details are expected "soon," likely tied to a Galaxy S26 Unpacked event.
The bigger question is whether other Android OEMs — and eventually Apple — will adopt a similar multi-agent OS model. If the pattern holds, the battle for the default AI assistant may give way to something more interesting: a battle for which agents earn a slot in the orchestration layer.
That's a fundamentally different kind of competition, and it's just getting started.
