When AI no longer requires you to reintroduce yourself in every conversation but remembers your profession and the pain points of your last project, artificial intelligence is quietly undergoing a qualitative shift from being a "tool" to a "companion." On November 6, at the 8th World Voice Expo and 2025 Iflytek Global 1024 Developer Festival, the digital human "Xiao Fei" not only engaged in natural conversations with visitors but also recommended restaurants based on historical preferences and proactively completed ticket bookings. This scene reminded many attendees of Samantha, the AI companion from the movie *Her*, who could read emotions and offer companionship. Behind this transformation lies Iflytek's newly introduced "personalized memory capability," built on the Spark X1.5 model, which constructs a personalized memory database for users, enabling comprehensive understanding of long-term profiles, recent feedback, and short-term dialogues.
As AI begins to remember user preferences and habits, our relationship with machines is being redefined. Over the past year, the competition among AI large models has shifted from "who is smarter" to "who understands you better." At the Voice Expo, Iflytek released the Spark X1.5 large model, which adopts a Mixture of Experts (MoE) architecture with 293 billion total parameters and 30 billion active parameters, doubling the inference efficiency compared to its predecessor. However, technical specifications alone are not the goal—the real breakthrough lies in how AI understands each unique individual.
Liu Qingfeng, Chairman of Iflytek, emphasized during the launch that realizing the full potential of AI requires overcoming four key challenges: independent controllability, integrated hardware and software, industry depth, and personalization. These four paths converge on a single objective—transforming AI from serving the masses to serving individuals. The personalized memory capability, developed based on Spark X1.5, addresses the critical technical challenge of transitioning AI from a functional tool to a personalized companion. This capability builds a dedicated memory database for each user, achieving a holistic understanding of long-term profiles, recent feedback, and short-term interactions.
For example, in the Spark Smart Cockpit 2.0, the system can remember user preferences for seat adjustments, air conditioning temperature, and travel habits through 54 dimensions and 2,808 memory anchors, turning the car into a "third space" that integrates life, work, and entertainment. This memory capability ensures AI is no longer a blank slate reset after each conversation but accumulates interaction experiences to form unique relational memories. This is the foundation for AI truly "understanding you" and a crucial step in its evolution from assistant to companion.
Memory alone is just data; the real measure of "understanding you better" lies in transforming this data into thoughtful services. In Iflytek's application ecosystem, personalized memory has already been implemented across multiple scenarios. In emotional companionship, Iflytek's "AI Star Friend" serves as a growth companion with a self-learning emotional model, proactively calling users when needed. It not only forms personalized memories based on conversations but also initiates contact when sensing user needs, elevating human-computer interaction from passive responses to active care.
In education, the Spark large model pioneered an error-cause system comprising three major categories, three levels, and over 4,000 tags, enabling precise analysis of students' learning gaps and achieving an "hour-level closed loop" from detailed homework corrections to targeted classroom teaching. In healthcare, the "Smart Medical Assistant" has become an invaluable aid for primary care doctors in over 800 districts and counties nationwide, providing over 1.1 billion AI-assisted diagnostic suggestions and significantly improving the standardization and accuracy of grassroots medical services.
A truly user-understanding AI cannot exist solely in the cloud. Through integrated hardware and software solutions, Iflytek is equipping "AI companions" with the ability to perceive reality. For instance, the Iflytek Smart Office X5 features an innovative eight-microphone array for superior noise resistance, achieving a 95.08% recognition accuracy in high-noise environments. These hardware devices are not just carriers of technology but bridges for AI to integrate into the real world.
From education to healthcare, from office work to emotional companionship, AI is making the leap from "helping you" to "understanding you better" across multiple dimensions. The "three-in-one" approach—emphasizing AI R&D, product application, and industrial cultivation—outlined in China's *New Generation Artificial Intelligence Development Plan* is becoming a reality. Companies like Iflytek, with their independently controllable domestic computing platforms, are offering the world a "second choice" for AI development.
Artificial intelligence is no longer just cold machines and algorithms but is gradually becoming an indispensable companion in human life. When AI can not only pass professional exams but also remember your preferences, speak to you in your favorite voice, and proactively reach out when you need it, the gap between us and the world of *Her* is no longer a technological chasm but rather the final polish of commercial implementation. Iflytek's exploration demonstrates that the ultimate goal of AI technology should not merely be efficiency enhancement but also understanding, empathy, and fostering human mental health and growth. This shift from instrumental rationality to value rationality is the core essence of "AI fulfilling humanity."
