A coalition of tech investors and AI companies is launching a US political action network called "Leading the Future" to influence AI legislation. The initiative is backed by venture capital firm Andreessen Horowitz, OpenAI president Greg Brockman and his wife Anna Brockman, as well as Perplexity and investor Ron Conway. The network plans to spend over $100 million on campaign donations and digital outreach to support candidates seen as tech-friendly and oppose those pushing for stricter AI regulations. Organizers Josh Vlasto and Zac Moffatt say the goal isn’t deregulation, but to promote "sensible guardrails." Initially, efforts will focus on four key states: New York, California, Illinois, and Ohio. Modeled after the crypto-focused Fairshake initiative, the network aims to work across party lines. Its main objective is to prevent what the industry sees as a fragmented patchwork of AI laws across the US.

Brave discovered a security flaw in Perplexity’s AI browser Comet that allows for so-called indirect prompt injection attacks. In these attacks, malicious commands are hidden in web pages or comments and are then interpreted by the AI assistant as legitimate user instructions when summarizing a page. During testing, Brave showed that Comet could be tricked into reading out sensitive user data, like email addresses and one-time passwords, and sending them to attackers. Perplexity responded by issuing updates, but according to Brave, the issue still isn’t fully resolved. Brave also offers its own AI assistant, Leo, in its browser and faces similar security challenges.

Nvidia has stopped producing H20 and 700,000 AI chips intended for China are now sitting idle.

After a temporary green light from the US government, Nvidia had promised Chinese customers about 700,000 H20 AI chips. These chips are stripped-down versions designed to meet US export rules, making them legal for the Chinese market. Now, a new directive from Beijing is forcing local companies to stop buying Nvidia chips over security concerns. As a result, thousands of finished chip dies are sitting unused at Amkor, a US-based packaging partner. The supply chain has ground to a halt, even though Washington and Nvidia had already reached a political agreement. The situation highlights how AI hardware is increasingly caught in the middle of geopolitical tensions. Earlier reports suggested the US is adding tracking chips to AI hardware bound for China.

Dynamics Lab has launched Mirage 2, the latest version of its generative game world engine. With Mirage 2, users can upload their own images - like sketches or photos - and turn them into interactive game worlds. The engine also lets players change the game in real time by typing in commands. Worlds can be saved and shared. While Mirage 2 makes clear technical gains over its predecessor, it still struggles with precise controls and visual stability. In both areas, Genie 3 from Google DeepMind is far ahead, but Genie 3 isn't available yet and likely requires much more computing power. A Mirage 2 demo is available online.
