The Windows software maker’s chief technology officer, Kevin Scott, was “very, very worried” when he looked at the AI model-training capability gap between Alphabet Inc.’s efforts and Microsoft’s, he wrote in a 2019 message to Chief Executive Officer Satya Nadella and co-founder Bill Gates. The exchange shows how the company’s top executives privately acknowledged they lacked the infrastructure and development speed to catch up to the likes of OpenAI and Google’s DeepMind.

The email was released late Tuesday after media organizations including the New York Times and Bloomberg intervened in the landmark antitrust suit to push for greater public access. The US Justice Department has argued that OpenAI’s ChatGPT and other innovations may have been released years ago if Google hadn’t monopolised the search market.

Scott, who also serves as executive vice president of artificial intelligence at Microsoft, observed that Google’s search product had improved on competitive metrics because of the Alphabet company’s advancements in AI. The Microsoft executive wrote that he made a mistake by dismissing some of the earlier AI efforts of its competitors.

“We are multiple years behind the competition in terms of machine learning scale,” Scott said in the email. Significant portions of the message, titled ‘Thoughts on OpenAI,’ remain redacted. Nadella endorsed Scott’s email, forwarding it to Chief Financial Officer Amy Hood and saying it explains “why I want us to do this.”

Microsoft has poured more than $13 billion into its partnership and backing of OpenAI, tapping the startup’s generative-AI technology to enhance its Bing search service, Edge internet browser and, most notably, integrate an AI Copilot service into Windows. Nadella has elevated the AI race to a priority at the company, also recruiting DeepMind co-founder Mustafa Suleyman to run its consumer AI business.

Nadella answered questions about the email when he testified at the trial last fall.

“As it relates to search, we wanted to sort of ensure that we could think about innovation in the search category with” large language models like those developed by OpenAI, Nadella said. But he later added that the “investment was not made with the narrow focus on just search.”

Microsoft and Google declined to make the email available when requested by reporters last year on the grounds that it would reveal sensitive business information. Media outlets pushed for its release, and Judge Amit Mehta last week ordered the companies to provide a redacted version, as the contents “shed light on Google’s defense concerning relative investments by Google and Microsoft in search.”

Google and the Justice Department will make closing arguments in the case on Thursday and Friday. Judge Mehta is expected to issue his decision later this year.

The case is US v. Google, 20-cv-3010, US District Court, District of Columbia.
