In 2019, Microsoft invested $1 billion in OpenAI due to concerns about Google’s advanced AI scaling. An internal email exchange between Microsoft CTO Kevin Scott, CEO Satya Nadella, and co-founder Bill Gates revealed Microsoft’s worries about being behind in machine learning scale compared to Google. Microsoft engineers took six months to replicate Google’s BERT language model due to infrastructure limitations. Initially dismissive of OpenAI and Google DeepMind’s AI efforts, Scott became impressed with their natural language processing models, realizing the capability gaps between Google and Microsoft. Nadella forwarded Scott’s thoughts to Microsoft CFO Amy Hood, expressing his desire to proceed with the investment. The heavily redacted email thread suggests Gates’ involvement in Microsoft’s relationship with OpenAI. Microsoft’s $13 billion investment in OpenAI has integrated its models into various products, positioning Microsoft as an AI leader. Nadella’s focus on AI and security for Microsoft in 2024 signals continued AI integration into their products.
