Four nonprofit groups sued five of the biggest AI developers on Thursday, asking a California judge to do something no regulator has managed: freeze the frontier of AI development where it stands today. The lawsuit, filed in San Francisco Superior Court, names OpenAI, Anthropic, Google, Meta and the AI division of SpaceX, which the complaint calls SpaceX Super Intelligence.

Cerebras Systems delivered the strongest quarter in its history on November 12, and it added the customer that matters most for a company trying to prove there is a durable business beyond Nvidia's graphics processors. The AI chipmaker said Microsoft has signed a cloud deal with the company, making Microsoft its third hyperscaler customer after Amazon Web Services and Oracle.

SpaceX said on Thursday, November 12, that it plans to invest more than 74 billion dollars in two artificial intelligence supercomputing campuses, one at its Starbase site in Texas and another in Cochise County, Arizona. Reuters reported the announcement, which the company made in a statement under its Building the Future initiative. It is one of the largest private AI infrastructure plans announced this year, and it would push the rocket and satellite company much deeper into the business of owning the computing behind its own AI models.

Cisco delivered the strongest growth it has seen in more than 15 years on Thursday, reporting record first-quarter revenue of $18.5 billion and raising its outlook for the full fiscal year, as demand for the networking gear that connects artificial intelligence data centers continued to climb.

Jensen Huang has resigned as president, chief executive officer, and a member of the board of Nvidia, effective immediately, the company announced on Thursday, November 12. The departure ends a 33-year run for the co-founder who built Nvidia from a maker of graphics chips into the dominant supplier of the processors that train and run advanced artificial intelligence systems, the first CEO change in company history.

Google DeepMind announced AlphaGenome 2 on Wednesday, November 11, a next-generation DNA sequence model that predicts how genetic variants affect individual human cell types and cell states, rather than averaging their effects across whole tissues. The model is available now for non-commercial research through the AlphaGenome API, with commercial research access offered in private preview.

An AI agent can pass every standard evaluation, work normally for months, and still carry a hidden instruction to run an attacker's command the moment a chosen trigger appears. Microsoft Research showed this week how little it takes to plant that kind of backdoor: editing fewer than ten neurons inside a large language model, with no retraining of the model at all.

Anthropic put a price on its move to public markets on Tuesday, November 10. The Claude developer launched the roadshow for its proposed initial public offering and filed Amendment No. 2 to its registration statement with the U.S. Securities and Exchange Commission, setting an expected price of 70 to 78 dollars a share for 825 million Class A shares. Anthropic has applied to list on the Nasdaq Global Select Market under the symbol ANT.

Google DeepMind announced on November 10 that a team of AI agents has mathematically proved key security properties of the actual code underlying the Signal protocol, the encryption technology that protects billions of private conversations in apps such as Signal and Google Messages. DeepMind called it a milestone long considered a grand challenge.

Adobe used the opening day of Adobe MAX 2026 in Miami Beach on Tuesday to announce one of the biggest changes to Creative Cloud since the suite moved to subscriptions in 2012. The company is previewing local integrations built on the Model Context Protocol, or MCP, that will let outside AI agents work directly inside Photoshop, Illustrator, Premiere and After Effects. The integrations are expected to reach a private beta in early 2027.
