Welcome to Tech Beat. Here are the stories shaping the conversation today.

Researchers at Tsinghua University have published what's being called a landmark paper on a technique they call Cache-to-Cache, or C-two-C. Rather than having AI models communicate through generated text, they exchange internal data directly, cutting humans out of the loop entirely and delivering a one-hundred-fifty percent boost in inference speed. The implications for how AI systems collaborate could be significant.

On a related note, the Electronic Frontier Foundation is raising alarms about DraftKings, accusing the sports betting giant of using artificial intelligence to sharpen the edge of behavioral advertising. The concern isn't just that the ads are targeted — it's that AI makes that targeting more precise, more persistent, and potentially more harmful to vulnerable users.

And in a story that will resonate with anyone who's spent years building a film community online, Letterboxd — the beloved movie diary platform — may be on the verge of an acquisition. A-twenty-four, Sony, and the New York Times are reportedly circling the company. The question, as always with these deals, is whether the thing that made it special survives the purchase.
