On September 15, AITO and HarmonyOS Intelligent Mobility issued a statement on their cooperation model: in the five areas of product definition, product design, brand marketing, channel retail, and service system, AITO will be led by Seres, with Huawei Device participating as an enabler, and AITO will remain part of the HarmonyOS Intelligent Mobility system. Maextro, Stelato, Luxeed, and Shangjie will maintain Huawei's full-process leadership. The two parties said that existing rights and subsequent services for AITO users will remain unchanged, but did not disclose an implementation timetable, operational details, or capital and equity arrangements.
On September 15, AITO and HIMA successively issued statements on their cooperation model. According to the statements from both sides, AITO remains one of the core members of the HIMA family and, effective immediately, will explore a new cooperation model under the HIMA cooperation framework.

Division of Responsibilities Adjusted: Seres to Lead Five Areas
The statement specifies that after the adjustment, five areas—product definition, product design, brand marketing, channel retail, and service system—will be led by Seres, with Huawei Device participating in enabling. This wording defines the lead and participating parties for each area, while emphasizing that AITO remains within the HIMA cooperation framework.
In statements on brand origin, both sides continued their previous positioning: AITO is jointly designed and built by Huawei and Seres, bringing together the joint investment of both teams and industry chain partners, and is a representative achievement of cross-sector integration and industrial upgrading. Based on the public text, cooperation between the two sides will continue, and the AITO brand will remain exclusively dedicated and operated, continuing to focus on high-end smart electric vehicle products and the full lifecycle vehicle experience.
It should be noted that the statements did not disclose a specific implementation timetable or operating rules for the new cooperation model, nor did they mention arrangements at the capital or equity level. How the relevant division of labor will be implemented and how the areas will interface with one another currently have no further public information.
User Benefits: Existing Benefits and Follow-up Services Unchanged
In response to user concerns, both AITO and HIMA addressed the issue in their statements, emphasizing that the existing rights and interests and follow-up services of all AITO users will not be affected, and that related services for users will remain unchanged going forward. At a time when the cooperation model is being adjusted, this statement provides a clear position for the expectations of existing owners and potential consumers.
Differentiated Landscape: Only AITO Adjusts; the Other “Four Jie” Brands Keep the Original Model
The scope of this adjustment is limited to the AITO brand. HIMA stated that Maextro, Stelato, Luxeed, and Shangjie will continue to maintain the cooperation model led by Huawei across the entire process, with the original cooperation mechanism unchanged. This means that within the HIMA system, two cooperation paths now coexist: for AITO, Seres leads five areas—product definition, design, brand marketing, channel retail, and service system—with Huawei Device participating in enabling; the other four brands continue to use the Huawei-led, full-process approach.

Ecosystem Synergy and Points to Watch Going Forward
At the technology R&D level, HIMA's wording remained unchanged, saying that in the future it will continue to work deeply with its five Jie partners on automotive intelligent technology R&D and continue to create high-quality smart vehicle products for users.
From an industry perspective, these statements addressed outside attention on AITO's role in the HIMA system, the division of cooperation, and user benefits, but there is still room for observation at the implementation level. First, the phrase “explore a new cooperation model” comes with no timetable, and the pace from statement release to actual implementation remains unclear. Second, after Seres leads the five areas, how the collaboration interface with Huawei Device's enabling will be defined needs to be corroborated by subsequent information. Third, after the two cooperation paths run in parallel, how HIMA's synergy efficiency at the channel and brand levels will change also remains to be seen.

As of press time, the relevant parties have not provided further explanation regarding the implementation timetable, operational details, and capital or equity arrangements for this adjustment. For practitioners following the 鸿蒙智行 system, the actual operation of 问界's new model will be an important reference for judging the system's future collaboration approach and market layout.
