On October 24th, the 9th Lenovo Tech World 2023 opened. Lenovo Group Chairman and CEO Yang Yuanqing delivered an opening speech with the theme of "AI for All, Making Artificial Intelligence Benefit Everyone", showcasing Lenovo's first AI PC, large model compression technology, AI Twin, and a series of AI innovation technology achievements. The CEOs of top global AI technology companies such as Microsoft, NVIDIA, Intel, AMD, and Qualcomm attended the conference and delivered speeches, while also disclosing multiple strategic collaborations. AI ushers in hardware transformation. Lenovo leads the AI PC in a new era of generative AI, and the big language model brings lighthouse guidance. However, the true implementation of artificial intelligence cannot be achieved without the load of hardware and devices. The Lenovo first AI PC showcased at the conference has made the ultimate carrier of AI a reality. AI PC will bring about a revolution in productivity. As a disruptive hybrid of devices, edge computing and cloud technology, AI PC will not only have powerful computing power and advanced AI technology, but also bring innovative interaction methods and visual experience, fully meet the needs of new generative AI workloads, and provide users with customized experience. AI PC provides privacy and data protection. Yang Yuanqing emphasized that thanks to Lenovo's large model compression technology, Lenovo AI PC has the ability to run personal large models and can run locally without involving cloud operations, thus ensuring personal privacy and data security. Personal artificial intelligence twin devices have become a digital extension of users, Yang Yuanqing said. Intelligent devices are like racing cars, and they are the ultimate carrier for artificial intelligence to reach end users. The future personal computer will be an artificial intelligence computer, the future mobile phone will be an artificial intelligence phone, and the future workstation will be an artificial intelligence workstation. On these devices and edge devices that support artificial intelligence functions, a local knowledge base will be established to better understand users. The personal big model will use personal data stored on devices or home servers for inference. Unless authorized by the user, their personal data will never be shared or sent to the public cloud. It can even predict tasks based on users' thinking patterns and independently find solutions. From this, the device is like a digital extension of the user, just like the user's twin, we call it the "personal artificial intelligence twin". Lenovo is working in this direction, bringing artificial intelligence technology to everyone and making it accessible. Soon, on everyone's AI PC, users will be able to create local knowledge bases, run personal basic big models, support artificial intelligence calculations, and utilize natural interactions. Enterprise level artificial intelligence twins provide support for intelligent solutions. Yang Yuanqing stated that enterprise level artificial intelligence twins are the sum total of a series of enterprise level artificial intelligence applications. They possess deep knowledge related to the enterprise and can ensure that relevant information is private and secure. They can extract relevant information from intelligent devices, intelligent edges, and private clouds within the enterprise or organization, and summarize and integrate it into judgments and conclusions,
