SAN FRANCISCO, June 2 (Reuters) - Microsoft ( MSFT ) on

Tuesday kicked off its annual Build developer conference in San

Francisco, showcasing a new computer called the Surface RTX

Spark Dev Box loaded with an Nvidia ( NVDA ) chip.

In an onstage keynote, Satya Nadella, Microsoft's ( MSFT ) CEO, said

the forthcoming computer was a "dream machine." There is a wait

list to buy the computer and Nadella said he is on it, too.

Microsoft ( MSFT ) executives are expected to outline how the

technology company plans to compete in the cloud, where it is

both an investor and a rival to firms such as OpenAI, and

increasingly on PCs.

Those laptop and desktop computers are becoming home to

tools such as OpenClaw, a piece of open-source software that can

direct groups of AI bots called agents to carry out everyday

tasks for users.

But OpenClaw, which has gained popularity in China and helped

rival Apple ( AAPL ) sell Mac computers, and other such tools

are also risky for most businesses to use.

Analysts expect Microsoft ( MSFT ) to work on making such agentic AI

tools safer for businesses and the world's 1 billion users of

its Windows operating system to use regularly.

They also expect more details on how Microsoft ( MSFT ) will let

developers tap a new Nvidia ( NVDA ) chip, unveiled on Monday, to help

bring AI directly to PCs. The Surface RTX Spark Dev Box follows

a laptop that Microsoft ( MSFT ) introduced with Nvidia ( NVDA ) this week, and

Microsoft ( MSFT ) executives showed it running an AI model with 120

billion parameters - a rough measure of a model's complexity -

that most PCs would not be able to load.

The chip will go into laptops priced to compete with Apple's ( AAPL )

premium offerings, and its release helped boost shares of both

Microsoft ( MSFT ) and major PC makers such as Dell Technologies ( DELL )

, though analysts said it may take time for businesses

to adopt the new machines.

Analysts also expect Microsoft ( MSFT ) to provide updates on its own

AI models, using which it aims to compete in fields such as code

completion with OpenAI's Codex and Anthropic's Claude Code.
