A.Dot 4.0 Released: SKT's AI Evolves Into a Personal Assistant That Understands User Intent

On August 4, SK Telecom announced that it has updated its AI service A.Dot to version 4.0, incorporating the latest AI technique known as "Agentic Workflow."

The newly applied Agentic Workflow is a technique in which AI agents go beyond simply executing user requests. Instead, they set goals based on conversations with users and sequentially plan and execute the necessary tasks.

SKT explained that with this update, A.Dot can now identify the user's hidden intentions within their requests and deliver the desired personalized results.

A.Dot 4.0 autonomously performs the four core elements of Agentic Workflow: ▲planning ▲utilization of available external tools ▲multi-agent collaboration ▲result review and issue improvement.

SKT implemented an "Agent Orchestrator" that analyzes user requests, plans the appropriate tasks, and connects the most suitable sub-agent. With the Agent Orchestrator, A.Dot automatically assigns the appropriate sub-agent to handle user requests after receiving them. In version 3.0, users had to manually select the agent for the desired function and submit their requests accordingly.

The Agent Orchestrator carries out its tasks in the following order: ▲"Input Reconstruction," which reinterprets the user's request ▲"Planning," which divides the reinterpreted request into steps and selects the appropriate sub-agent for each ▲"Task Management," which calls the selected sub-agent.

In particular, during input reconstruction, the AI agent incorporates not only the most recent conversation history with the user but also information stored in memory to contextualize and clarify the meaning of the latest request. The "memory" used here is a kind of storage device that identifies, extracts, and saves information valuable to the user from conversations. Users can view or delete stored information at any time through the "Memory Management" menu.

The "Multi-Agent Collaboration" feature has also been introduced, enabling cooperation among sub-agents. In this feature, multiple sub-agents, each with their own functions, work together. Music and securities agents, which were previously offered separately, have now been incorporated as sub-agents, allowing users to access services such as music recommendations and stock information within a single chat window.

For example, if a user requests, "Recommend songs that match today's weather and play them all," A.Dot checks the weather information, recommends suitable music, and then delivers the playlist to the user.

An SKT representative stated, "We expect that as A.Dot transitions to an Agentic Workflow-based structure where various agents collaborate, its scalability will be greatly enhanced."

A.Dot's existing features have also been further enhanced. In the "Schedule" feature, users can now add, modify, or delete multiple events at once. Registered events can be directly linked to Google Calendar or Outlook.

The "Voice Mode" has been improved so that even during responses, A.Dot can immediately recognize additional user questions or utterances, ensuring uninterrupted conversations. Also, even if a user makes multiple requests in a single utterance, they can be processed simultaneously.

An "Emotional Mode" has been added, allowing users to engage in role-play style emotional conversations with the AI. The conversation modes are provided in three forms: ▲Mind Counseling ▲Advice from the Moon (dream interpretation and fortune-telling) ▲Childhood Friend.

The user interface (UI) has also been revamped to enhance usability. The left tab menu now allows users to easily check their favorite music and stocks, and the "Schedule" feature has added background images and colors for improved visual elements.

Meanwhile, SKT announced that the number of A.Dot subscribers has surpassed 10 million after 22 months since its official launch. The monthly active users (MAU) number about 8.1 million. SKT explained that A.Dot subscriptions are being made through various customer touchpoints, including the app, web, phone, Btv, and Chatting+.

Kim Yonghoon, head of SKT's A.Dot Business Division, stated, "Version 4.0 marks a significant turning point as A.Dot evolves into an agent that remembers and assists in daily life," adding, "We will continue to advance A.Dot so that it can deeply understand users' hidden needs and naturally blend into their daily lives, providing personalized experiences."
