Hello and welcome to 2-Minute Tech Briefing from Computerworld. I'm your host Arnold Davick, reporting from the floor of the New York Stock Exchange. Here are the top IT news stories you need to know for Tuesday, December 2nd. Let's dive in! First up from NetworkWorld. Microsoft is facing new pressure in its AI infrastructure push. This comes after losing two senior leaders responsible for data center and energy strategy, Nidhi Chappelle, head of AI infrastructure, and Sean James, Senior Director of Energy and data center research, both announced their departures, while Chappelle has not announced her next move. James is heading to Nvidia, intensifying competitive heat in the GPU arms race. Their exits come as Microsoft grapples with power constraints grid interconnection delays and the challenge of sourcing enough accelerators to meet skyrocketing demand. And from InfoWorld, Google has rolled out major updates to its Gemini API. The changes are designed to support the newly released Gemini 3 model. The improvements include simpler controls for managing the model's thinking. A new parameter called thinking level lets developers choose how deeply Gemini reasons before responding. It can be set to high for complex analysis or low for faster, lower cost tasks. The updates aim to strengthen Gemini 3's reasoning, autonomous coding and agentic intelligence capabilities.

The Microsoft AI research division unintentionally published 38TB of critical information while posting a container of open-source training data on GitHub, according to cybersecurity company Wiz. Secrets, private keys, passwords, and more than 30,000 internal Microsoft Teams communications were discovered in a disk backup of the workstations of two workers that was made public by the disclosed data. Wiz emphasized that because Microsoft does not offer a centralized method to manage SAS tokens within the Azure interface, it is difficult to track them. Microsoft claimed that the data lead did not reveal customer data, that no customer data was leaked, and that this vulnerability did not put any internal services at risk.
