This memorandum analyzes and stress-tests arguments in favor and against the inclusion of internal deployment within the scope of the European Union Artificial Intelligence Act (EU AI Act). In doing so, it aims to offer several possible interpretative pathways to the European Commission, AI providers and deployers, and the legal and policy community at large based on Articles 2(1), 2(6), 2(8) of the EU AI Act. Specifically, this memorandum first analyzes four interpretative pathways based on Article 2(1)(a)-(c) supporting the application of the EU AI Act to internally deployed AI models and systems. Then, it examines possible objections and exceptions based on Articles 2(1)(a), 2(6), and 2(8), with particular attention to the complexity of the scientific R&D exception under Article 2(6). Finally, it illustrates how Articles 2(1), 2(6), and 2(8) can be viewed as complementary to each other, once broken down to their most plausible meaning and interpreted in conjunction with Articles 3(1), 3(3), 3(4), 3(9), 3(10), 3(11), 3(12), 3(63), and Recitals 12, 13, 21, 25, 97, and 109.

翻译：本备忘录分析并压力测试了支持与反对将内部部署纳入《欧盟人工智能法案》（EU AI Act）适用范围的论点。基于该法案第2(1)条、第2(6)条及第2(8)条，本文旨在为欧盟委员会、人工智能提供者与部署者以及更广泛的法律与政策界提供若干可能的解释路径。具体而言，本备忘录首先基于第2(1)(a)-(c)条分析了四种支持将《欧盟人工智能法案》适用于内部部署人工智能模型与系统的解释路径。随后，本文检视了基于第2(1)(a)条、第2(6)条和第2(8)条可能存在的反对意见与例外情形，特别关注第2(6)条下科研研发例外的复杂性。最后，通过结合第3(1)、3(3)、3(4)、3(9)、3(10)、3(11)、3(12)、3(63)条及序言第12、13、21、25、97、109段进行解释，本文阐明当第2(1)条、第2(6)条与第2(8)条被分解至最合理含义时，三者如何形成互补关系。
