This week in global AI was dominated by a leadership change at Nvidia, a major model launch from Google and Anthropic's march toward an IPO. This Global AI Roundup for Nov. 14, 2026, covers the most important developments from Nov. 12 to 13.
Beyond those three stories, competition in data center chips heated up again with AMD's Instinct MI400 series. On the legal front, U.S. courts are getting tougher on the misuse of AI in litigation. Some items below are still media reports, and we flag their status in each section.
Quick answer: The biggest AI stories this week were Jensen Huang's resignation from Nvidia, Google's broad release of Gemini 4 Hydrogen and Anthropic's IPO price range of $70 to $78 per share. AMD also launched its Instinct MI400 chips, while Notion handled a data exposure tied to a third-party AI provider.Nvidia Changes Leadership, Kress Named Interim CEO
Nvidia's board announced on Thursday, Nov. 12, 2026, that Jensen Huang had resigned as president, CEO and board member, effective immediately. Huang led the company he co-founded for 33 years.
CFO Colette Kress was named interim CEO and will keep her CFO role. The board also appointed Harvey C. Jones as chair, a position Nvidia has never had before. The search for a permanent CEO will consider internal and external candidates.
Nvidia gave no reason for the resignation in its press release. The company said its results for the third quarter of fiscal 2027 will still be released on Nov. 17, 2026. That report will be the first test of investor confidence under the new leadership.
Gemini 4 Hydrogen Rolls Out Broadly
Google DeepMind released Gemini 4 Hydrogen across Google AI Studio, the Gemini API, Gemini for business, the Gemini app and Google Search. The model has a 1 million-token context window.
API pricing is set at $1.50 per million input tokens and $7.50 per million output tokens. In the Antigravity platform, an orchestrator can switch between Gemini 4 Carbon and Hydrogen within a single session. Hydrogen access in Antigravity requires a paid Google AI Pro or Ultra subscription.
According to Google's internal testing on Terminal-Bench 4.0, Hydrogen's success rate is close to Carbon's while using 24% less quota and finishing tasks 19% faster. These figures come from Google and have not been independently verified.
Anthropic's IPO Draws Closer
In an amended prospectus filed with the SEC on Nov. 10, Anthropic said it plans to offer 825 million shares at $70 to $78 each. TechCrunch calculated the implied valuation at about $1.4 trillion.
The filing also lists roughly $900.9 billion in spending commitments, with about $70.7 billion due within the next 12 months. An entity controlled by the founders will retain 50.1% of general voting power.
Bloomberg reported that the IPO will be priced on Wednesday, Nov. 18, with trading set to begin the next day under the ticker ANT. The company has not officially confirmed that timeline, and the offering has not been completed.
AMD Launches Instinct MI400
AMD introduced its Instinct MI400 accelerator series, made up of the MI430X, MI450X and MI455X. The MI430X carries 432 GB of HBM4 memory and up to 288 teraflops of FP64 performance, targeting both scientific computing and AI.
AMD says the MI430X's memory capacity is 50% larger than Nvidia's Vera Rubin platform. That comparison is AMD's own. On the same day, Dell launched PowerEdge R9825 and R9815 servers built on sixth-generation EPYC processors.
Notion Responds to Insights Data Exposure
Notion disabled its Insights feature and disconnected AI inference provider Fireworks following a security incident on the Fireworks side. Notion said fewer than 1% of workspaces were affected.
On Nov. 13, Notion said exposed third-party API keys had been reported to their issuers the day before. Fireworks said its default zero-data-retention services were not affected. The investigation is ongoing.
U.S. Court Sanctions Lawyers Over AI Citations
U.S. District Judge Sharion Aycock of the Northern District of Mississippi sanctioned four attorneys in a contract dispute. They had filed documents containing fake case citations generated by AI.
Two out-of-state attorneys were barred from practicing in the district for two years, and two others were disqualified from the case. One attorney was fined $2,500. The sanctions will also be forwarded to bar authorities in Mississippi, Louisiana and Texas.
The case adds to a growing list of penalties for lawyers who fail to check AI-generated work, and it is a reminder for the legal profession everywhere.
