With the continuous development of artificial intelligence technology，artificial intelligence large language model plays an increasingly important enabling role in terminal equipment. The terminal large language model is being gradually applied on mobile terminal devices such as mobile phones，personal computers，smart cars，and large language model all-in-one PCS，to meet the growing use needs of users in offline scenarios. The mobile phone terminal has become a “testing ground” to explore the innovation of the terminal large language model scene. The personal computer has become an important terminal for the universal benefit of large language models. Large language model all-in-one computer provides low-cost，high value-added private computing power for large language model training. The large language model of vehicle terminal has a new impact on automotive research and development and business models. At present，the terminal large language model has the advantages of low comprehensive cost，local reliability，privacy and personalization，but it also faces some challenges in computing power，storage and transmission，power consumption and maintenance. In the future，with the technological evolution of large language models and the development of large-scale applications，terminal large language models will continue to expand to more application scenarios.
