The court documents released in the Musk vs. Altman case reveal the internal decision-making process of Microsoft's investment in OpenAI in 2017. The documents show that Microsoft CEO Satya Nadella and OpenAI CEO Sam Altman had already begun considering collaboration in the AI field. However, Microsoft executives had a complex attitude towards investing in OpenAI. On one hand, they were concerned about the large amount of money involved, and on the other hand, they worried that OpenAI might turn to Microsoft's competitor Amazon and speak negatively when leaving.

In the summer of 2017, OpenAI demonstrated its robot defeating professional players in the game Dota 2. A few days later, Altman replied to Nadella's congratulatory email, proposing a larger-scale cooperation with Microsoft to support OpenAI's next phase of research. To expand the Dota 2 project, OpenAI needed a large amount of computing power, which exceeded the Azure quota provided by Microsoft at the time. Altman pointed out that the required resources would cost approximately $300 million according to Azure's pricing. This number shocked Microsoft executives.

Jason Zander, then head of Microsoft Azure, stated in an email that if Microsoft was to invest such a large amount of money, it must be able to obtain significant incremental revenue. A few months later, Altman proposed another solution, hoping to gain funding support through a partnership with Xbox. At this point, Microsoft executives discussed whether they should provide more Azure support to OpenAI.

Kevin Scott, Microsoft's Chief Technology Officer, also participated in this discussion, expressing concern about OpenAI possibly turning to Amazon. He pointed out that not supporting OpenAI could lead to negative public relations impact, as OpenAI's influence within the AI community was rapidly growing. After a year of in-depth consideration, Microsoft finally decided to invest $1 billion in OpenAI.

Today, the close relationship between Microsoft and OpenAI has become complex. OpenAI is currently renegotiating the agreement with Microsoft, considering bringing AI models and tools to Amazon's cloud services. Recently, OpenAI even told its employees that the agreement with Microsoft limited their ability to provide services in enterprise customer environments.
