Samsung Reimagines Bixby: From Voice Assistant to “Device Agent”
Samsung is fundamentally shifting how users interact with their electronics. On March 31, 2026, the company officially launched a redesigned Bixby, evolving it from a traditional voice assistant into what Samsung calls a “device agent.” This transition marks a move away from simple command execution toward agentic AI—a system that understands intent and context to autonomously execute complex tasks on a user’s behalf.
The Shift to Agentic AI
The core of this evolution is a complete overhaul of Bixby’s architecture. According to Jisun Park, Corporate Executive Vice President and Head of Language AI at Samsung Electronics’ Mobile eXperience (MX) Business, the latest Bixby uses a Large Language Model (LLM) at its core. This allows the system to interpret a user’s intent rather than simply matching spoken words to a set of pre-defined commands.
To achieve this, Samsung rebuilt individual device functions as “callable agents.” This means the LLM can invoke specific functions on the fly based on the context of the conversation. For example, if a user tells Bixby their eyes are tired, the agent doesn’t just provide information; it can recommend and actively switch on the Eye Comfort Shield.
Key Capabilities of the New Bixby
- Contextual Awareness: Bixby now understands device status and capabilities to provide tailored solutions and more relevant responses.
- Intuitive Device Control: Users can utilize natural language to adjust settings, such as asking which settings to change to reduce eye strain.
- Cross-Device Ecosystem: Bixby acts as a single conversational layer across the Samsung lineup. Users can control a robot vacuum or turn on air conditioning from their phone while away from home.
- Integrated Intelligence: The system integrates LLM capabilities and incorporates Perplexity’s AI to provide seamless access to web-based information within a single flow.
Overcoming Language Barriers
Developing a global agent requires overcoming significant linguistic hurdles. Jisun Park noted that Korean is “structurally brutal” for language models, but Samsung’s development team managed to surpass their original Korean performance targets by a significant margin, ensuring the device agent performs reliably across different languages.
Key Takeaways: Bixby’s Evolution
| Feature | Traditional Voice Assistant | New Bixby “Device Agent” |
|---|---|---|
| Core Logic | Command matching | Intent interpretation (LLM-based) |
| Action | Waits for specific commands | Autonomously figures out how to achieve a goal |
| Scope | App-based execution | Single conversational layer across all devices |
| Control | Manual/Specific triggers | Context-aware natural language control |
The Future of the Galaxy Experience
Samsung’s long-term strategy is to position Bixby as the “brain” of the Galaxy ecosystem. By moving toward a model where the AI agent handles the heavy lifting, Samsung aims to reduce the user’s reliance on navigating through individual apps. Instead, the device agent serves as the primary starting point, turning the smartphone into a comprehensive control surface for the entire household.
