Transforming into an office in the car, the onboard AI becomes an office assistant that can assist in generating copy and organizing meeting minutes; I can still chat and chat with you like an old friend of the car owner; Faced with more complex urban road conditions, big models can empower autonomous driving to achieve precise driving... Under the AI big model craze, all industries are following the trend and exerting their imagination. In the automotive industry, a competition for big models to get on the car has also quietly begun. In recent months, multiple car companies such as Chery, Changan, Ideal, Lantu, and Great Wall have announced the launch of large models, including those that have independently developed large models and those that have collaborated with technology companies such as Baidu, Huawei, and iFlytek to launch large models. However, while car companies are singing loudly that big models will reshape the industry, some industry insiders also believe that there is an "overheating" situation in the current use of big models, and their commercialization prospects are currently unclear. Large models have gradually become a trend in the first half of this year. Over a hundred general and vertical large models have been released in China, presenting a trend of "Hundred Model Battle". Various industries are also actively embracing large models, and the automotive industry is currently in the wave of intelligent innovation. On August 17th, Chery's high-end brand Xingtu announced that its new series of Star Era ES will debut the Mars cognitive model of iFLYTEK - LION AI. The relevant person in charge introduced that the platform will be developed in three stages: the first stage is the application of intelligent cockpit, such as AI voice assistants that can understand user needs and provide personalized services; The second stage is product level application, achieving the integration of intelligent driving and intelligent cockpit, as well as customized services for "thousands of cars and thousands of changes"; The third stage is for enterprise applications, including upgrading marketing service scenarios and enterprise digitization. In recent months, there has been a constant stream of official announcements about the installation of large models. As the first general model released in China, Baidu's ERNIE Bot has been announced by nearly 10 auto companies, including Dongfeng Nissan, Hongqi, Great Wall and Geely; Geely, Zhiji and other car companies have also collaborated with Alibaba on the integration of the Tongyi Qianwen big model; At the beginning of this month, Huawei released the Hongmeng HarmonyOS 4 system, which is connected to the Pangu model. It will be built on the first Huawei Smart Select model, the Luxed, in collaboration with Chery... In addition to car companies and technology companies working together, there are also car companies working on self-developed vertical large models in the automotive field. Among them, Ideal Automobile announced the launch of its self-developed cognitive big model, Mind GPT, on Home Technology Day in June this year; GAC Group recently announced the launch of the latest research and development achievement of AI big model technology - GAC AI big model platform. Earlier, Chery New Energy, Great Wall, NIO, and Xiaopeng also applied for registration of GPT related trademarks, revealing their intention to enter and exit the large model. Multiple car companies are laying out grand plans for the installation of large models due to intelligent upgrades or security vulnerabilities. However, currently, reporters have noticed that the main focus of the installation of large models is mainly on the field of intelligent cabins. Wake up the car AI through voice and complete various service functions, which is the most accessible field for users to see and touch in the present. But while intelligent upgrades bring convenience, they may also come with security vulnerabilities. The intelligence of an ideal car is really convenient, but there is a bug（
