SEATTLE (Reuters) - Microsoft ( MSFT ) talked up new tools on Tuesday aimed at encouraging programmers to build the AI-focused technology into Windows-related software as it races against Alphabet, Amazon.com and Apple to dominate the emerging technology.

At a developer conference in Seattle, Chief Executive Satya Nadella promoted new application programming interfaces, or APIs, that make it easier for developers to tap in to AI technology offered by Microsoft ( MSFT ).

The company said 1.8 million developers are now using Github Copilot, Microsoft's ( MSFT ) generative AI tool that helps computer programmers be more productive.

"What stands out to me as I look back at this past year, is how you all as developers have taken all of these capabilities and are applying them, quite frankly, to change the world around us," Nadella said during his keynote address at the Build conference.

Microsoft ( MSFT ) detailed new features for its Copilot AI software that helps business productivity applications such as email and its Teams video and text chat product. At its developer conference last week, Alphabet's Google unveiled a similar batch of AI tools to help people with office applications.

Microsoft ( MSFT ) announced details of its new developer tools last week.

Shares of Microsoft ( MSFT ) were up 1.2% at $430.67 on Tuesday afternoon after earlier hitting a record high of $432.97 earlier in the session. Microsoft's ( MSFT ) stock has now rallied 14% in 2024.

Also aimed at developers, Microsoft ( MSFT ) said last Thursday it would offer its cloud computing customers a platform of AMD AI chips that will compete with Nvidia ( NVDA ), whose graphics processing units have become the gold standard for AI computing.

The platform of AMD chips created by Microsoft ( MSFT ) uses networking technology made by Nvidia ( NVDA ) called Infiniband to string the processors together.

On Monday, Microsoft ( MSFT ) debuted a line of Copilot+ personal computers with AI features such as software that lets users search through their past actions in nearly any software. The new computers feature Arm-based processors made by Qualcomm ( QCOM ).
