According to the Financial Times, OpenAI disbanded its preparedness team at the end of last month. The job of the preparedness team was to assess if models posed serious risks and develop ways to mitigate those risks. (You know, like the possibility that it could go rogue and hack another company.) According to FT, responsibility has instead been divided up for specific areas like bio and cyber, then moved into existing teams.

Stripe has finalized a deal to acquire OpenRouter, according to a new report in Bloomberg.

To address this problem, tech companies are investigating ways to supply their own power to data centers instead of relying entirely on the grid. One option is to use on-site hydrogen fuel cells. These clean energy generators combine hydrogen and oxygen to produce electricity, using a catalyst to speed the reaction, reduce energy loss, improve overall performance, and extend the fuel cell’s operational lifespan. The problem is, existing catalysts lack the necessary activity and durability to meet data center performance targets.

Tim O’Reilly’s yardstick for measuring the worth of a company, person, or society has long been create more value than you capture. It’s no surprise that O’Reilly—publisher, internet pioneer, VC, conference organizer, and dispenser of tech wisdom—is applying that metric to the way people design and use AI. Specifically, he’s pushing for a future where open-source AI is an elixir for the masses. He worries that, like Microsoft in the 1990s, today’s hyperscalers are trying to lock users into their products. So he is promoting efforts to open-source AI technology—not only making critical technical details such as neural-net weights accessible, but unlocking the whole stack of an AI system, giving control to designers and users.

Leading US AI labs such as OpenAI and Anthropic are releasing cheaper models as they fight to retain cost-conscious customers who are switching to cut-price alternatives from Chinese rivals.
